Hecarim Build Guide by Riealone

Hello everyone!
My name is Aleksei, Im 23 years old. Peak elo - 570lp EUW. Discord Riealone#0070. I live in Saint Petersburg, Russia. Playing League since season 5 and main Hecarim from the same time. Feel free to add me in Discord and ask about anything - will gladly help you

I make educational Hecarim streams with full commentary about what I do and why (with saved Vods, so you can just watch and learn any time if you miss live). Want to teach as many people as I can to play my favorite champion. You can find it here:
https://www.twitch.tv/riealone

Ok, lets start now!

Pros:
1. Hecarim is easy to learn, doesn't have skillshots and has simple mechanics
2. Champion is strong in current meta and overall, especially in elo below D2. If you learn how to play him, some macro and game knowledge - it is for sure a really good way to climb
3. Fun to play
4. Good ganks and teamfights
5. Can snowball hard snowball in early and midgame
6. Engager / Initiator gameplay - you take the game in your hands by making a good call, pick and initiation. Which requires good macro and game knowledge, yes

Cons:
1. Vulnerable to pre-6 invades
2. Kind of falls off in the late game
3. Struggles vs current meta-junglers. You can see it in my mathups section - favorable ones mostly are out of meta

Conqueror + Ravenous Hunter in my opinion is the only way to play Hecarim right now. Phase Rush and Predator are just straight up worse because of Nimbus Cloak and Warpath nerfs. You still can play it, but personally I don't see in what situation it can be more useful

I was testing different builds a lot, and this one is my main and favorite - high damage and sustain bruiser. The key is Conqueror with Ravenous Hunter. The heals that rune provides are just insane. And then we stack it with Spirit Visage healing increase, Triumph, Elixir of Wrath and Death's Dance heals, MS and extra tankiness. Now we can just duel anyone, win any skirmishes and live in teamfight really long while providing insane amount of damage. You can decide what to do in game. Peel your teammates, deal with enemy bruisers and assassins, dive and destroy backline, reduce enemy healings, splitpush - this build is the most flexible as it possible can be and allows you to successfully do actually everything

Conditioning or even Aftershock is never an option if you want to be healthier. If you want more tank - you just play Zac, Nunu & Willump, Sejuani or Rammus, because Hecarim is not a tank for sure

Hecarim is an AD melee caster with bruiser-initiator gameplay. So, in general, we need to engage, deal damage, survive the burst and sustain after that to keep living and being useful. Based on this best stats for us are: AD, HP, Armor and MR, Ability Haste, Sustain. MS is also good, but we simply get more than enough of it from Ghost, so it's not really worth to take items with that stat on purpose (especially after Warpath nerf)

Right now I can't be sure about what is 100% correct items build. Lets consider it with (in my opinion) best mythic item for Hecarim Divine Sunderer (read more about mythics in "Possible questions" section, (1.)):

My own build and recommendation - Death's Dance + Spirit Visage > Sterak's Gage (with adding early anti-heal somewhere here when you need it). You can also buy Sterak's Gage as first legendary (also it's fine to build it as second legendary item when there is a good opportunity for that) item against well mixed AD and AP damage. When, for example, enemy team has Elise jungle and 2-3 AD laners - Sterak's Gage suits well here when you need to protect yourself from both AD and AP damage. Another way to do that (doesn't matter what legendary item you buy first) - buying resist components Cloth Armor and Null-Magic Mantle. They provide you some cheap resists which stack pretty well with 400 HP from Divine Sunderer. I prefer doing this instead of buying Sterak's Gage as my first legendary item because I really need extra Ability Haste early. And I'm not a fan of Ionian Boots of Lucidity (described down below in "Possible questions" section, (3.))

These 3 items ( Death's Dance, Spirit Visage and Sterak's Gage) have insane synergy - damage, HP, resists, MS, shield, sustain, Ability Haste - all you need. And I also like to build Death's Dance as first legandary item for its insanely valuable passives for Hecarim and build path - Armor, AD and Ability Haste. Suits so good in midgame since you have 400 HP from Divine Sunderer which is really a lot. That affords you to play more aggro. And then you close it out with Spirit Visage and Sterak's Gage when you need to be more tanky in the end of midgame. Thats how I see it. With Trinity Force it's way harder to do because it gives only 200 HP

IMPORTANT!
You should not build Death's Dance/ Spirit Visage into literally pure full AP/AD enemy team comps, even though these items is your core build. Stack Armor or MR with Sterak's Gage when these comps happen and just get your free win. Builds for example:
* Full AD - Divine Sunderer > Plated Steelcaps > Bramble Vest (sometimes it's worth to complete Thornmail instantly) + Sterak's Gage + Death's Dance > other items with Armor / HP / Damage
* Full AP - Divine Sunderer > Mercury's Treads > Sterak's Gage + Spirit Visage > other items with MR / HP / Damage

When to build situational items:
* Black Cleaver - into tanks, when enemies build some Armor or as more aggro replacement of Sterak's Gage (sacrifice shield for Ability Haste and extra damage)

* Ravenous Hydra - in theory fun item to buy when you are ahead or when enemy team doesn't build anti-heal. But it makes you really squishy. With this item you need to deal damage to survive and pray that enemy team won't build anti-heal. For example when you buy Sterak's Gage - you just become straight up more tanky by default. I'm still not sure about this item. Let it be here for now

* Chempunk Chainsword - the question here is about completing this item or sit with Executioner's Calling in games when you need anti-heal. I think just look at you current game, Chempunk Chainsword provides useful stats for Hecarim. It's worth to complete this item if you have some free gold or don't have better things to build at this moment

When to build highly specialized items:
* Serpent's Fang - mostly into double support botlane who just have limitless shields ( Lux, Seraphine, Sona, Lulu, Janna). Or when enemy has Ivern jungle and shielding support, why not

* Silvermere Dawn - into HEAVY CC and against Mordekaiser or Malzahar

* Maw of Malmortius - into full AP comps when you already have some HP and need more damage

* Serylda's Grudge - the ideal scenario for this item is mobile enemy comp with Armor. Lets just compare it with Black Cleaver - AOE slow vs health and armor reduction for your team. I think this item is just a second option for Hecarim to deal with armor and it can shine in some situations

All these items have sweet and useful stats for you, so now it's way easier and more rewarding to build them than before (yes, old Mercurial Scimitar, I'm looking at you)

You can copy my items set which I use and paste it in League client "Items" section. It's just an ascetic and comfortable for me to use version of items from this guide:

1. Lets talk about mythic items:

Divine Sunderer - in my opinion, suits you the best. 400 HP, 20 Ability Haste, 40 AD, Spellblade, %-health damage, heal, penetration

Trinity Force got mini-reworked. Lets analyze:
* -10 AD (350 gold) against +10 Ability Haste (266 gold) which is a nerf in terms of gold efficiency
* The more Ability Haste you have the less valuable it becomes with further buys. In my core build ( Death's Dance + Spirit Visage) we already have enough Ability Haste, so I would prefer AD more
That means it is a straight up nerf

Stridebreaker - I am the Spellblade slave and I can't play without Sheen. You can try it, but I don't see how its active AOE slow (which is really nice on ganks) + mythic MS passive can be better than Spellblade from Trinity Force or Divine Sunderer. Because most of the time you will have Mythic + Boots + 2 Legendaries for the whole midgame and then you start building third one when it's getting closer to late game. Mythic passives are just too small to make your choice around them: 6-9% MS or 20-30% AS or 10-15% Penetration

Stridebreaker active can be used as a gap closer (like Nidalee Pounce, Kindred Dance of Arrows or Graves Quickdraw - keep in might that active's CD might be quite short since it can be reduced by Ability Haste) and an AOE slow to keep enemies within your autos + Rampage DPS range and deal free damage. It's the same what Darius does - he slows you with Crippling Strike or Apprehend and then lands empowered Decimate on you for free. Or when Kha'Zix slowes you with evolved Void Spike to just keep you close and kill. Another example is Mordekaiser Realm of Death to just make sure you cant run from him (of course his ultimate can be used for other purposes, disable a jungler with Smite or peel carries from an assassin for example). All of these strategies have the same idea with Stridebraker's active

Stridebreaker is also worse than Sheen in DPS-oriented fights, mostly 1v1 and 2v2. When enemy do not try to run from you and you just both stay and try to outdamage each other because you can't tell who will win this skirmish. Clearly Sheen will do way more here than 1 active proc from Stridebreaker when you don't need that AOE slow

All 3 mythics are fine, they don't affect your rest build - for all of them you buy same legendary items. Lets make a conclusion:
* Divine Sunderer - ultimate choice which you can take every game, especially good into tank setups. I play only with this mythic
* Trinity Force - into squishy teams, you can try it and play if you like
* Stridebreaker - into mobile and kite comps or jungle matchups, you can try it and play if you like

2. Legend: Tenacity is always good. Legend: Alacrity is for really no CC games or for people who need some extra DPS and can dodge most of CC. It just makes you more vulnerable to mistakes. I go Alacrity when enemy team doesn't have a lot of CC. For beginners I would recommend to go Tenacity and then try Alacrity when you are more confident with Hecarim

3. Hecarim has 2 best boots options - Plated Steelcaps and Mercury's Treads. Choice here is always in defensive stats which he needs really hard - never buy Mercury's Treads for only extra tenacity since you can just take it with Legend: Tenacity

There is a pattern about boots and tenacity:
Look at enemy team and decide which type of damage will be dominant - physical or magical

*If enemy has mostly physical damage and none/a bit cc - go Plated Steelcaps + Legend: Alacrity
*If enemy has mostly physical damage and medium/huge amount of cc - go Plated Steelcaps + Legend: Tenacity
For example Morgana support doesn't count as huge amount of magical damage

*If enemy has mostly magical damage and none/a bit cc - go Legend: Alacrity + Mercury's Treads
*If enemy has mostly magical damage and medium/huge amount of cc - go Legend: Tenacity + Mercury's Treads. This is the only situation when you can take both tenacities

As you can see, boots in ALL your games should be use ONLY for resists. CC problem is for Legend: Tenacity rune. You might ask what to do if enemy team is mostly AD and has a lot of CC (only 30% from Legend: Tenacity rune will not be enough) - NEVER go Mercury's Treads in this situation only for extra tenacity (you get 51% with both rune + boots - not 60% as you could think, it doesn't stack well). You will just suffer. Only way here is learning and practicing how to dodge enemy CC spells

Few words about Tenacity and Slow Resistance:
*Slow resist decreases slow effectiveness
*Tenacity decreases slow duration
*For example you are slowed by 50% for 10 seconds
*30% tenacity gives 50% slow for 7 seconds
*30% slow resist gives 35% slow for 10 seconds

So this is why you shouldn't buy Boots of Swiftness as slows counter with 25% Slow Resist - Mercury's Treads with 30% Tenacity give you the same effect but in a different way. And 25 MR + 5% more Tenacity is obviously better for Hecarim than extra 15 MS and 200g cheaper. Even vs Zilean going Mercs is more worth - he can easily stun you with Time Bomb, and Swifties would be useless here. But I think (in theory) these boots can be viable sometimes into heavy slows or when you have exact money for that buy or some good early combo (for example when you have 1300g and Boots you can go for early game ganking combo of Boots of Swiftness + Sheen, something like this). Although I wouldn't do it - my way is just to follow towards core build

Ionian Boots of Lucidity is another questionable option. They give you 20 Ability Haste which is huge, but we already have enough with just core build - Death's Dance + Spirit Visage. I guess (in theory) it can be a viable option when you take Sterak's Gage as your first legendary item if you can afford yourself to sacrifice defensive stats for early Ability Haste aggression since mythic alone doesn't provide enough of it. Is it worth to do that or no - that's another good question. Not for me at least

4. I prefer Coup de Grace because I don't feel Last Stand synergizing good with our sustain build. In my games it will always deal less damage because of my playstyle. But I still would recommend you to test both and check in match history which one dealt more damage overall, because this may vary from player to player

5. Triumph is the only option. Presence of Mind is just worse since we got buffed mana per level and mana restoration in jungle/river. Triumph just makes you live longer and provides insane outplay potential. That rune won so many skirmishes and whole games for me

6. Eyeball Collection is a bit better than Sudden Impact in my opinion and for my own gameplay. Eyeball gives you permanent power for clearing camps and fights, when Sudden Impact is better only in early game. I've tested Sudden Impact a lot and it just feels weaker overall for me. I sacrifice some power that Sudden Impact provides you in early game for extra 18 AD. For me and my playstyle it's better. I don't recommend you to take Zombie Ward for extra vision because you need to farm mostly and not play around river like other ganking junglers ( Elise and Kindred for example). I believe Eyeball Collection is the most consistent and reliable option for Hecarim

But a lot of people is going Sudden Impact for extra power since the game beginning, so I believe it's a personal preference. Play with both and decide for yourself what do you prefer more - early or mid/late power

7. What to take? Ghost vs Ignite and Red vs Blue smite?

At first, please go Ghost by default, it has received 2 big buffs. Like literally in 100% of your games (since we don't buy Dead Man's Plate in this build as core item) and you can buy Executioner's Calling right after completing Divine Sunderer

Blue and Red smite are both viable and good in specific matchups. You should buy Red smite vs hard dueling, healing and invading enemy junglers to just match them. If you want to catch Kindred you go Blue smite (and if enemy team has a lot of ranged champions), for dueling Xin Zhao you go Red smite. Red smite is also good into champs like Irelia, Yasuo, Jax and other melee bruiser. Also it helps with assassins by lowering their damage - Kha'Zix, Talon, Zed etc. Think about what will be better into current enemy setup

Ignite + Conqueror WAS a possible option if you need more power in early / early midgame (when we had Nimbus Cloak before nerfs), but later on it falls off really hard in compare to Ghost. Right now Ignite is just dead for Conqueror Hecarim because you will never go Nimbus Cloak in its current state
Ignite also could help you really much in hard early game matchups (especially against healing champions like Xin Zhao, Rengar, Olaf and Trundle)
And one more thing - Flash is never an option

8. Elixir of Wrath I believe is the best option for Hecarim. Extra AD and healing is so good for you to get in the late game. Elixir of Iron is a good alternative when you need some extra HP

9. In small runes you go AS, AD and Armor (last small rune can be changed with scaling health or MR into AP-heavy enemy setups). +10% AS is more gold efficient and a bit stronger in early game (better clear and stronger skirmishes), and +6 AD makes Rampage to deal +4 more damage and it's really good since we spam Q so hard. I believe AS is better. Especially when we go Divine Sunderer

10. Executioner's Calling vs Bramble Vest. The 35 armor stats that Bramble Vest provides are straight up better than 15 AD from Executioner's Calling. But it is also hard to use against non-adc champions - for example Fiddlesticks or Vladimir just will not autoattack you. Bramble Vest is good when you need to lower enemy autoattackers healing and into AD heavy enemy setups. And again - enemy marksmans can just focus your teammates instead of you, the 150 armor 3000 HP bruiser. Executioner's Calling provides you with way easier and ultimate Grievous Wounds application - you decide who will not heal. Also sometimes you don't want to get your armor overstacked - most likely you will already have 40 armor from Death's Dance, but it is setup and game scenario situationals about how much armor do you need. And of course you need to upgrade these items into Chempunk Chainsword or Thornmail to get mythic passive

The main rule - ALWAYS look where enemy jungler starts, track him over all game and give that info to your team. Doesn't matter if it's an easy or hard matchup - doing that is your key to victory

You can start both Blue or Red Buffs. The choice here depends on game setups - you want to gank specific lane, countergank, avoid enemy jungler, loop your camps for further pathings etc. Clear speed is the same, so you just choose where to start every game and where you want to be after clear. From my experience starting Blue Buff is a safer option, because enemy do lvl 1 cheese mostly on your Red Buff, and then enemy junglers more often invade you lvl 3 at your Blue Buff - in both cases when you start from Red Buff

You need to think in every game which pathing will be better in current situation. For example, you take 3 camps - Red Buff > Krugs > Raptors , then meet enemy Kindred on your Blue Buff. This should NEVER happen, because you completely lose your early game here. You can't fight a strong early game jungler with 2 Buffs when you have only 1 Buff

You should determine your route by keeping in mind lot of things - who you want to gank, jungle and lane matchups, prios, your game plan etc. Now I want to share with you some my analytics and thoughts about smart moving in jungle in different scenarios:

Fullclear in easy matchups
Krugs clear - used to be the best option, now it is even with Blue Buff clear. Best time to do this route is when you are against farming or tank junglers. Red Buff > Krugs > Raptors > Greater Murk Wolf > Blue Buff + Gromp > gank / countergank / duel enemy jungler / Rift Scuttler > back. The best option is fullclear 6 camps before Rift Scuttler spawns at 3.15 with leveling Q again at level 3 (starting E lvl 3 is a safer option against strong early game junglers, but it takes a bit longer to clear). But be careful of enemy jungler invade and keep in mind the matchups. Then you should be on Krugs around 4.00 after base. Farm them, then gank somewhere or do the same clear again to get lvl 6. This path works with Blue Buff start too

3 and 4 camps clears in hard matchups
If you play vs lvl 3 invading junglers ( Elise, Lee Sin, Olaf, Trundle, Rek'Sai, Kindred, Rengar, Graves etc) and/or when enemy laners have massive prio ( Talon vs Kassadin, Teemo vs Nasus) you should be really careful!!! In this situation you can't just do regular Krugs clear (and especially you can't take Q again at lvl 3). You should do this:

You clear 2 Buffs and 1-2 camps to get lvl 3 and then play situationally (another camp, gank, countergank, invade or something else). This option is the safest one. Normally you start Buff > Greater Murk Wolf + Raptors > Buff (sometimes vs aggro lvl 2 junglers like Lee Sin you can do Buff > 1st small camp > Buff > 2nd small camp or even Buff > Buff > 1 big / 2 small camps, depends on where you want to be and meet/not meet enemy jungler). Keep in mind that Gromp is the hardest camp for you. And now you can fight enemy jungler, take your other camps or counterjungle enemy (for example Raptors against Warwick), gank, countergank or something else situationally. Doesn't matter which Buff to start in terms of clear speed, it's about where you want to be at lvl 3. In this route we can choose what to clear with 2 Buffs - 1 big camp ( Gromp or Krugs ) or 2 small camps ( Raptors and Greater Murk Wolf ). Clearing 1 big camp is good when you expect lvl 2 Buff steal from you enemy, because you will get lvl 3 off 3 camps when you vertical jungling (your Buff, big camp, then when you see enemy invade you invade by yourself and steal his buff). Clearing 2 small camps is a bit faster, healthy, brings you more gold, but it's harder to vertical jungling, because you either need to steal 2 enemy camps or soak some lane xp to get lvl 3

Also you can clear your bot or top side jungle to get lvl 3 and then play situationally - continue farming, gank, invade enemy jungler or fight him in your jungle. But you need to have a decent game knowledge to play this - will enemy jungler invade you or not, his clear speed and paths, your lanes matchups (obviously you are going to chase enemy jungler with Ghost and Boots). If, for example, enemy has Talon or LeBlanc vs your Kassadin, Draven, Kalista, Camille - you really need to think twice, because it turns up too risky

About lvl 3 ganks. For your first clear you can lvl 3 gank a side lane where you started clearing. Red Buff > Raptors > Krugs > gank (also works with Blue Buff > Gromp > Greater Murk Wolf ). But be ready to lose you blue side jungle for that move. It's a dangerous strategy. After that, if you didn't kill enemy laners, they can prevent you from going vertical jungling. Or enemy jungler can just do Red Buff > your Blue Buff > his Blue Buff with help of enemy laners. And you just simply lose here. Safe option here is ganking midlane after 3 camps and then rotate to your other side camps and Rift Scuttler . Also another safe option is lvl 3 ganking lanes with 4 camps clear, because enemy will not be able to steal your camps

5 camps clear - something in between
Default clear when you skip Gromp or Krugs and get lvl 4 after killing Rift Scuttler . This path can be a next step in 4 camps clear route or a semi-farm-ganking route - when you are not really sure what do you want to do and where to gank around Rift Scuttler . Neutral risks, xp, gold, ganks - just an average route

Useful jungle tricks
You also need to ask your midlaner to cover you (or just be aware) from lvl 1 Red Buff invade (especially when enemy team has Galio with his Flash + Nimbus Cloak combo, Pantheon, Blitzcrank etc) if you start it and ward bushes (tribush, near river and Raptors / pixel brush on river). Just always be aware of that, tell your team and try to not miss your smite. Sometimes you should just leave it. Or vertically invade by yourself. Or start your other buff and then do something. Anyway, this cheese strategy is really hard to counter and I hope it will die really soon like funneling. I see only 1 good counter here - look at matchups and start opposite Buff. If enemy has Darius and Rengar - start botlane Buff with possible vertical jungling later, because they will lvl 1 invade you 100% on top. And if enemy bot has Kalista, Thresh and Graves - start topside Buff. Pattern is simple

If you play vs lvl 2 dash junglers ( Nidalee, Kindred, Graves etc) be aware of:
1. Their lvl 2 cheese (they take their Red Buff and cheese you on your Gromp if you take it right after Blue Buff). To counter it obviously just skip Gromp and do 4-5 camps clear or start other side and go for vertical jungling
2. Their lvl 2 Buff steal. You should ward it and go for vertical jungling if they come to steal it. To prevent this you need to do ward trick in ALL your games, because even no-dash junglers can and will lvl 2 steal your other Buff. At the start of the game go to you opposite Buff, start backing at 0:55 and place a ward into Buff bush at the last second. Then buy Oracle Lens and it will be ready to use. This secures you from counter jungling and helps to clear enemy wards. Against no-dash junglers it's better to ward pixel brush on river or other possible entrances to your Buff. Keep in mind that enemy jungler can assume that and go long no vision way, but it's really high elo mind games which almost never happen
Also you can start your clear from enemy jungle Buff, but be even more aware about enemy laners, their covers and wards

About Dragon . You need to try to play around botlane and take every single dragon. But it's always situational. If your bot is hard losing, you should just give up first and second drakes, go gank mid/top and take Rift Herald (maybe even 2 times). Or you can try to help your losing lane, get shutdown gold and comeback. It is up to you and your game knowledge

Use your Rampage in the midair of Devastating Charge animation, because your damage scales with movement speed. But sometimes you should Q without jumping (but with E activated). For some reasons - kite enemy around, or cast Q two times and then jump (Q + midair Q) so he cant escape double Q and you finish him with one shot, or when you want to run behind him or change direction

Don't cast Rampage in midair of your autoattack animation - auto will be a bit cancelled because Q can't hit at the same time with autoattack, and you lose some DPS. The best way is to cast Q right after your autoattack deals damage or right before your autoattack. But not in midair. Hecarim Rampage doesn't work like Zed Shadow Slash and Skarner Crystal Slash which you can just spam non-stop without any cancels - they can hit spell and autoattack at the same time. That doesn't mean much or give you some big advantage, but sometimes that small DPS amount can matter in close fights. Just try to not spam Q thoughtlessly. You will get used to it fast, it's really not hard

Use your Spirit of Dread properly. Don't waste it at the start of combat. It's worth to instacast it for 2 Conqueror stacks when you gank 2v1 top and you are not going to die, but you need to ALWAYS keep it in head and use W for the most profit in teamfights

Advanced trick with Spirit of Dread. Sometimes it's better to wait until you have full stacked Conqueror, because it gives you extra AD -> you deal more DPS, so your W will heal more. That requires a lot of knowledge about how much damage you will deal/take with current items, matchups and game situations (can you afford yourself to hold W or you need to cast it earlier to start healing and get 2 Conqueror stacks). It will come with experience, start training that trick from time to time. It can for sure win you a lot of fights which you would lose normally (especially 1v1 and 2v2 in early/mid game). Also it's not a good idea to press Q and then W - you just miss healing. Should always be W > Q (if possible of course), keep that in mind also

Try to bait enemy's Flash with your Devastating Charge. So don't cast it from the far away. If you can't outrun it, better dash in the direction where enemy is gonna flash to follow him with the leap animation instead of knocking him away. Sometimes you even can not activate it at all and just walk up ( Ghost helps). Or activate it when enemy notices you and starts to run. You try to move behind him and knock back to your teammate. Even if he flashes away it's worth and you have done all you could
And when you are already in melee range hold also hold your Devastating Charge and wait when enemy tries to escape with flash. For example when you sit in bush and enemy just walks into you - start damaging him with autos and Rampage, then use your E when he flashes out and get a free kill. Which is not possible if you waste your E in the beginning of fight, CD is too long
You can interrupt abilities like Tristana Rocket Jump, Rek'Sai Tunnel, Bard Magical Journey and Zac Elastic Slingshot with your E
You can use E as auto reset when you need to do it in close fights for instant burst. That works exactly like Camille Precision Protocol and Trundle Chomp

Your Onslaught of Shadows makes you unstoppable. Unstoppability provides immunity to displacements, (including suspension, knockdown, Realm of Death and The Show Stopper), sleep and stasis. The effects of other types of crowd control and Fate's Call are deferred until the unit is no longer unstoppable, where their remaining duration may still affect them.
Sometimes it's really good to keep your ult and use it to dodge some СС. Great example - you duel Yasuo and he gets 2 stacks of his Steel Tempest on you. When he presses his Q again you just use your ult to not let him use his ultimate. Your ult can be used almost like Fiora Riposte to dodge enemy CC, but you take damage. Same idea
Also aim you ult behind enemy to fear them back. Advanced trick - R more behind to counter their flash. Enemy flashes - still dead
You can ult through Azir Emperor's Divide when he casts it and when there is a wall already
If you use your Onslaught of Shadows during Mordekaiser Realm of Death animation, you will not be send into his realm and Realm of Death goes on CD. Also works with Sett The Show Stopper - he will just fly away without you
Also you can dodge sleep from Zoe Sleepy Trouble Bubble by pressing your Onslaught of Shadows after bubble already hit you. Same with Lillia Lilting Lullaby - simply doesn't work on you
You can also dodge Syndra Scatter the Weak and many other champions with their CC abilities
During R animation it's still possible to use Q,W and E. Really useful in some cases - for example you can cast R over enemy to just fly further (to another enemy champion or any other purpose) and kill him only with Q + R damage if you calculated it right

Advanced trick with Onslaught of Shadows and Devastating Charge combo. Your ultimate allows you to knock enemy with E even when you are stunned in R animation if enemy is in range of your E where you end your ultimate. Let me explain. You use your E, then R behind Twisted Fate and he uses his Yellow Card on you when you are flying in your ult. You get stunned, but if you right click on him right after ending your R - he will be knocked back with E even if you are stunned. Works with some other champions too. For example Cassiopeia Petrifying Gaze

There is another trick. Sometimes you want to use your Onslaught of Shadows right after you jump on enemy with Devastating Charge. R here is only for extra burst damage and/or CC immune. Your R is unavoidable this way - enemy gets CC'ed by your E

You can steal Baron Nashor and Dragon with your Devastating Charge, Onslaught of Shadows and Smite combo. You deal really big damage and can save the game if you are a bit lucky and time smite perfectly

One more thing about your Onslaught of Shadows and Devastating Charge combo. When you press E and then R behind enemy you can actually change direction of your E knockback by just moving around enemy while he is feared with your E activated to deliver enemy into your teammates

You can disturb enemies when they cast their key abilities with your Devastating Charge (and with your Onslaught of Shadows when it's worth to waste). For example Malzahar Nether Grasp, Ornn second part of Call of the Forge God, Karthus Requiem and other abilities. Also you can jump over walls with your E targeting creeps, neutral monsters, enemy champions and wards

The most important! Be a shotcaller!
Always talk to your team about your plan, what you want to do, where you will gank, when they should back, go side, track enemy jungler, everything. Be a leader in your team. Hecarim rewards that insanely

For example:
"care enemy jungler top, im bot"
"top you alone, just farm, I go take drake"
"lets get soul and baron right after, they cant contest"
"wait me red and gank bot"
And everything like this. If you have a decent score and your previous info/shotcalls were successful, your team will listen to you. That will actually help you to win more games

In general you need to farm up, take some kills, objectives and then kill 2-3 enemy players with a good engage. Repeat until you win. Lets consider in more detail:

Early game
Your goal here is getting Divine Sunderer. Focus on farm and ganking when it's free. Like this - farm, track enemy jungler, gank/countergank with Onslaught of Shadows or Ghost and try to take Dragon and Rift Herald . Then farm again

Mid game
Only difference with early game - people start grouping. Engage with your Onslaught of Shadows to get a free pick or land it on 2-3 enemy players. Take objectives and back to farm

Late-mid/late game
This is your time to shine! All you have to do - track all 5 enemies using minimap and make a great shotcall pick with your Onslaught of Shadows and Ghost. All what we have done before was for this moment (getting yourself and your team stronger, taking Dragons, Heralds and Towers). Every good initiation from you now makes victory closer (with dead enemies you take Baron Nashor , Elder Dragon , Inhibitors and, eventually, Nexus). At this time of game making it 5v4 is your key to victory. You should also look for a good initiation on 1, 2, 3, 4 or even 5 enemies. Whenever they make a positioning mistake you catch them and win off that

The common thing for every state of the game - Hecarim is a flexible champion. You can engage and peel you carries really effectively. Here is just a one thing to mention - please hold your Spirit of Dread (we discussed it earlier) and Onslaught of Shadows. This ultimate is one of the most powerful in the game. If you can reach enemy with only your Devastating Charge - hold it. Wait for the perfect moment to use it. For example, when 3+ enemies can be hit, when they focus you or your allies really hard (to save a life), when all your allies dealing damage to enemy, when you engage on carry with Devastating Charge and he flashes out and more more possible scenarios. That's what defines a good Hecarim player - smart management of your abilities, macro and game knowledge

There are three things you HAVE TO do if you want to be a good player:

1. Use Target champions only as toggle. Everything is simple here - stops you from autoing creeps and towers. Also when you gank and use Devastating Charge on minion, attack tower on dives. I have it binded on ` key and on my mouse side button

2. Use Attack move on cursor. For me it's Shift + Rightclick. Saves you some milliseconds even with camps farming, when you entering a bush you autoattack enemy instantly, when enemy uses Zhonya's Hourglass or goes out of invis like Kha'Zix for example, when you stop enemy jumps with your Devastating Charge, when you move instead of attacking enemy and a lot more other situations. Just keep in mind that Attack move on cursor DOESN'T work with Target champions only - you still will autoattack creeps and towers. So use it cleverly

3. Always check minimap with peripheral vision. Every few seconds. And also disable minimap movements

These 3 simple steps will make you play on a different level. Will be hard to get used to it, but it's absolutely worth
