Hello I am Gibune I have played this game since season 2 and currently I am diamond. I main the champion Jinx. she is a versatile adc compared to the rest as she is able to switch between two different guns to change her auto attacks for different situations. she also features a global ultimate, Super Mega Death Rocket!. Right now Jinx is a solid hard carry, she has lots of damage but the lack of mobility which makes her hard to play. The best thing about Jinx in my opinion is the insane damage she can output, this is a good example of some of the damage she can do when she gets ahead. Play Video

Pros

+ great poke with Switcheroo! and Zap! + Flame Chompers! is great for setting up ganks + attack speed buff from Switcheroo! helps win trades easily + Good global ultimate that helps in teamfights and executing enemies

Jinx is great for solo queue and really good in duo queue. She doesn't have a built in escape but Flame Chompers! is great for getting away. her passive Get Excited! is good for chasing champions and also running away after destroying a tower. her Switcheroo! is good for poking from afar with the extra range from fishbones while the attack speed buff from pow-pow allows you to win trades. her Zap! allows you to poke from afar as well and slows the enemy.

Cons

- no reliable mobility source - her Zap! can be hard to hit and same with Super Mega Death Rocket! - Flame Chompers! takes a bit to arm - the mana drain from fishbones will go through your mana pool easily

Jinx has notable weakness's, having no mobility will make you have to rely on either your positioning or you supports capability to peel for you and keep you safe. her abilities are hard to land and if you miss them you will be punished. her Zap! also has a high mana cost at rank 5 and can drain your mana really quickly.

We pick precision as it gives us the best runes for Jinx. For our first option we take Coup de Grace as it increases our damage low health targets so we can proc our passive asap in fights. Legend: Bloodline is easily the best choice for Jinx of the Legend choices as we need the lifesteal to be able to get to late game and minimise the damage in the early game Triumph gives us a nice bit of healing after a kill so we can go deeper in the fight with our Get Excited!Last but not least we have Fleet Footwork for our keystone which is amazing for Jinx. It gives us sustain when we get our energised attack and gives us move speed so we can run away from any dangerous foes or catch up to low hp enemies. It also synergises with Rapid Firecannon which gives us the energised attack more often. For our secondary tree we can skip resolve for sustain as we have Fleet Footwork and Legend: Bloodline and go for Sorcery for more damage. We pick up Celerity which gives us extra movespeed to run away and more damage based on our movespeed which works nicely with Get Excited!, we also take Gathering Storm to give us even more attack damage with works really nicely with the rest of the build and gives us a lot of damage in the late game.

what keystone rune is best for Jinx?

I think the precision keystones on Jinx are a bit of a preference thing. At the moment Lethal Tempo is straight garbage and even though it seems like it would be perfect on Jinx its so lacklustre that it doesn't work still. Press the Attack is good if you want to do a lot of damage to one target like a tank such as Maokai to have Get Excited! procced early on to do a lot of damage but this leaves you more vulnerable compared to having Fleet Footwork which in my opinion is the best choice on Jinx right now. It is a worse warlords bloodlust from season 7 but is the best option as it gives us the much needed survivability as that is what Jinx lacks. We don't need to amp up her already massive damage, we just need to able to survive to do the damage which Fleet Footwork does for us by providing movespeed and lifesteal on every energised attack.

what summoner spells are the best for Jinx?

well I think Flash is a must on jinx as she is immobile and the next summoner spell should be Heal the movespeed and health it gives you are to hard to give up although you could go Cleanse against cc comps but Quicksilver Sash is a cheap item you can get and is better. these summoner spells should be the standard spells as they just almost necessary until the meta changes. heal also helps with doing huge baits, this can lead to kills if you draw the enemy adc to kill you and then heal and your jungler ganks.

you should always put a point into Super Mega Death Rocket! when you can since its your ultimate you should be maxing Switcheroo! first as the bonus stats it gives is really strong as it helps win trades, then max Zap! as it is the next most important ability you need you max this second because in lane its not easy to land. last but not least you max Flame Chompers! the stats per level is not really needed because it doesn't increase snare time so you max it last.

Get Excited!
your passive Get Excited! is a strong passive but can sometimes never be used. when you get a kill, assist or destroy a turret you gain 175% movespeed that decays over 6 seconds and gives 15% attack speed. This is good for getting away from enemies after you destroy turrets or to reposition yourself in fights after you get a kill and also do more damage.


Switcheroo!
Switcheroo! is one of the reasons jinx is a unique adc, you have two different types of auto attacks to choose from. its sort of like Jayce with his ult that switches him from ranged to melee except with jinx its two different types of auto attacks. In minigun form your auto attacks grant bonus attack speed for 2.5 seconds stacking up to three times but the first granting two times the amount of attack speed. In rocket form your auto attacks have increased damage, range and has splash damage. The negative is that it has a slow attack speed until you have Get Excited! stacks.


Maximum Attack Speed:
30 / 55 / 80 / 105 / 130%
Enhanced Range:»
600 / 625 / 650 / 675 / 700
COST: 20 MANA PER ATTACK

• your rocket form makes it easy to poke in lane.
• the bonus attack speed from minigun form will destroy tower quickly.
• this skill is what will make or break a true jinx player.
• your rocket form is very good for teamfights especially when the enemies are all clustered together.
• rockets have very good waveclear.
• minigun shreds tanks late game.

Zap!
Zap! is a strong spell that most people underestimate when it is actually awesome. it scales really well off your ad gives a slow for 2 seconds and vision if you hit a enemy!, it truly is a game changer sometimes.

Physical Damage: 10 / 60 / 110 / 160 / 210 (+ 140% AD)
Slow: 30 / 40 / 50 / 60 / 70%
COOLDOWN: 10 / 9 / 8 / 7 / 6
COST: 50 / 60 / 70 / 80 / 90 MANA

it is giving 10% slow and 50 damage aswell as reduced cooldown each level which is not bad but not as good as Switcheroo!

• it deals very high damage and has a high range making it a strong poke tool.
• the vision it gives can be important instead of face checking use your Zap! and you will spot enemies if you hit them
• the slow can be really helpful for getting a pick on a target.

Flame Chompers!
Flame Chompers! is your main self peel that you need to use correctly as it has a long cooldown. You throw them out then after 0.7 seconds they arm snaring anyone who steps over them and dealing magic damage over 1.5 seconds. if no-one steps on the chompers they will detonate after 5 seconds.

Magic Damage: 70 / 120 / 170 / 220 / 270 (+ 100% AP)
COOLDOWN: 24 / 22 / 20 / 18 / 16
COST: 70 MANA

now the stats look good for leveling up right? well they are its just landing these chompers aint the easiest and your not really looking to do magic damage so that's why we max this last.

• the snare can mean life or death depending on how you use it.
• Flame Chompers! is really good for following up some hard cc from your support.
• they can be used also to zone out the enemy from going where you placed them.

Super Mega Death Rocket!
Super Mega Death Rocket! is very strong in the right hands. It is a global execute as it does more damage the lower health they have. this is a very good ability for teamfights and for laning as it can secure kills and do some heavy damage.

MIN. PHYSICAL DAMAGE: 25 / 35 / 45 (+ 15% Bonus AD) 」(+ 25 / 30 / 35% of target's missing health)

• this spell can be used to do damage from anywhere on the map.
• if you shoot it right this can turn the tides of any fight.
• if you are afraid of missing this skill you wont use it, you need to trust yourself.
• it cannot hit minions

we take Berserker's Greaves as they give us attack speed and that increases our damage per second.

First we build Infinity Edge. We usually get this item after Runaan's Hurricane but make sure you get a B. F. Sword before Runaan's Hurricane and also a Pickaxe if you have the money

we get a Runaan's Hurricane so now Runaan's Hurricane seems to me like the strong choice now as it gives more crit chance. Runaan's Hurricane goes very well with your rockets and is a must in any build.

We build Rapid Firecannon usually after we have our core as building two attack speed items on jinx is very strong and the extra range it gives us makes this item the best for us to pick up.

we build Lord Dominik's Regards as it gives us armor penetration and lots of it, with this item you will start to shred through anyone with the passive it has.

we get a Bloodthirster as it gives us much needed attack damage and lifesteal, the shield it gives scales with level so it's better for late game. The lifesteal is very helpful for surviving teamfights and sustaining after getting poked.

we sometimes get a Phantom Dancer instead of Rapid Firecannon for if we need the passive. A defence item is not recommended as we need as much damage as possible to deal with tanks. Despite saying that phantom dancer has a very nice damage making enemies deal 12% less damage to you.

now Statikk Shiv is a bit situational atm I find that some games when you are ahead you should get Statikk Shiv this item helps with some wave clear but I believe Phantom Dancer and Rapid Firecannon is better in every other situation.

Mercurial Scimitar is a very strong item as it can easily replace a bloodthirster whilst giving us defense stats. The Quicksilver Sash component is the main reason you would get this item. Having a cleanse as an item on a 90 second cooldown is very strong and it allows you to get away from harmful cc.

Guardian Angel is a very good situational defence item now. It's cheap has good armor and magic resist and the passive that we know the item for. Try not to buy this item too much as it lowers your damage output a lot unless they have 2 or more assassins.

there are 3 game phases in a game of league there are

EARLY GAME, MID GAME AND LATE GAME.

EARLY GAME

early game is all about minion kills in lane. you should aim for about 100cs at 12 minutes, this will give you a lead over your opponent If they cant last hit. When the opponent tries to last hit, hit them with an auto attack if you have no minions to last hit. Most matchups tend to not go jinx's way but with an aggressive support some easy kills can be picked up.

MID GAME

mid game is about 15-20 minute mark. you should have atleast 100-200cs. depending on how you went in lane will dictate your mid game. if your team is ahead and you won lane, you should roam with you team and try to take objectives. if you lost lane though you should stay in lane and try to kill minions, you can also freeze the lane so your opponent can't come bot to farm. heres a link if you don't know how to freeze the lane

LATE GAME

this is where things get fun or tough for you, its hard to cs without getting ganked so you have to teamfight and stay with your team. In teamfights you should hang at the back of your team, once the teamfight arupts poke with fishbones and hit the most important enemy while keeping yourself safe so if that means attacking the tank you go ahead and do that. once the enemy cc is gone and you feel safe go in with POW-POW to get more attackspeed. try to get your team to focus on baron and dragon as that gives you massive advantages.
