Hey guys,
My name is Goliath. I've played League of Legends since season 2 and have mained top lane since season 3. I've been high Diamond in every season since season 4, peaking at Master tier. League of Legends has always been the main game that I have stuck with over the years.

Here is my OP.GG for anyone interested.

If you want to see me play, maybe learn a thing or two, or ask me some questions, you can find my stream here. Stop by some time, I'm always down for giving advice and helping you improve.

If streams aren't up you alley, you can also check out my YouTube channel here. I'm going to start uploading informative videos, as well as stream and gameplay highlights.

If you want more general info, like when I upload, or update, a guide, then you can find my twitter here.

If I'm offline on twitch but you still want some pointers or just wanna chill, then feel free to join my discord server and hit me up.

Why Gragas?

If you want to play a tank with a bit of magic damage that can make some big plays then I think you should give Gragas a try. Gragas can also be surprisingly consistent as a champion, mainly due to the CC he provides, and the fact that his abilities can be game changing if he hits them. I see Gragas is one of the more fun tanks because he can actually do a lot of damage early game if you hit your abilities. He also has a good chance of winning lane, and also transitions into late game fairly well.

Another thing to take into consideration is the fact that his abilities heavily rely on skillshots and timing, so if you're a player that enjoys that kind of gameplay, then I'd pressure you to at least give Gragas a shot.

TL;DR: If you like being a tanky drunk that focuses on skill-shots and is capable of pulling off some big plays, or if you just really like getting wasted, then you'll like Gragas.


+ Decent mobility.
+ Good engage.
+ Good peel.
+ Sustains well.
+ Tanky in most situations.
+ Decent damage for a tank.


- High Mana costs.
- long cooldowns.
- Abilities rely on skill shots.

I think pros outway the cons a lot with gragas because items will help with mana and cooldowns so the only real con here is abilities being skill shots which isn't that bad.

- Sorcery -

Damaging an enemy champion with an ability hurls a comet at their location, or if Arcane Comet is on cooldown, reduces its remaining cooldown.

Adaptive Damage: 30-100 (based on level) (+ 20% AP) (+ 35% bonus AD)
Cooldown: 20-8 seconds

Cooldown Reduction:
Single Target: 20%
Area of Effect: 10%
Damage over Time: 5%

This rune is amazing on Gragas top since you're going to be poking fairly often with Barrel Roll(Q); since your Q slows them your comet will always hit them as well. All-in-all this just adds extra poke damage to your laning phase, which is great.

Hitting enemy champions with a spell grants 25 maximum mana, up to 250 mana.

Cooldown: 15 seconds

Upon earning 250 mana, Manaflow Band restores 1% of your missing mana every 5 seconds.

Gragas tends to have some early mana problems since you're poking so much, and also using your abilities for for the occasional sustain, so extra mana regen is a must have.

Gain 10% cooldown reduction at level 10.

Each percent of CDR exceeding the CDR limit is converted to an adaptive bonus of 1.2 Attack Damage or 2 Ability Power.

I personally like this rune while playing Gragas since cooldown reduction is extremely valuable on him. CDR is super important, as Gragas has pretty long cooldowns, and you'll often need your spells up to be at your most useful. The CDR also synergizes with the sustain gained from Happy Hour(Pas), so in general, this is basically just a huge value rune.

Your next ability hit sets champions on fire, dealing 20-60 bonus magic damage based on level after 1 second.

Cooldown: 20 seconds

I take Scorch since Gragas is super poke-heavy while in lane. This is kind of a weak rune, but it has secured me a few kills with the extra bit of damage, so I think it's still decent since you are a poke champion.

- Resolve -

After taking damage from an enemy champion, their next three spells or attacks against you deal 15-40 less damage (at levels 1-18).

Duration: 3 seconds
Cooldown: 45 seconds

Bone Plating is just a solid rune for top lane right now. It has a pretty long cool down, but it basically guarantees a winning trade whenever it's up. Make sure you try and trade when it's up, since it'll reduced damage three times after it activates.

Start the game with an additional 50 health. When you get 4 takedowns, consume that health to gain an adaptive bonus of 9 attack damage or 15 ability power.

I personally run this rune most of the time since the added HP early game helps so much for laning phase, and it turns into AP later, which is also useful when playing Gragas.

Note: if you're against a ranged or poke matchup you should take Second Wind.

Flash: This spell is kind of a "must" on most champions, and very important on Gragas. You can Body Slam(E) + Flash for a stun that they cannot react to, and can also Flash + Explosive Cask(R) to catch somebody out.

Teleport: Always take teleport, just too much value for top lane, since you can use it to join fights and gank for bot lane.

Happy Hour

Range: N/A
Cooldown: 8
Cost: N/A

Gragas takes a drink from his cask every time he uses an ability, instantly restoring 6% of his maximum health.

Happy Hour: This is your only sustain in lane, so try to time it with how you use abilities if you're low HP if you want to stay in lane. In my opinion this passive is actually super underrated and is your key to winning a lot of top lane match ups. Basically you can just keep taking trades and then healing up with this, and eventually you'll choke them out of lane. However, you have to be smart with it, and should never overextend into a bad fight. Even a small "even trade" will end in your favor in a lot of match ups because of this passive.

Barrel Roll

Range: 950
Cooldown: 11 / 10 / 9 / 8 / 7
Cost: 60 / 65 / 70 / 75 / 80

Gragas rolls his cask to a target location, which can be activated again to explode after arriving or will explode on its own after 4 seconds, dealing 80 / 120 / 160 / 200 / 240 (+70% of ability power) damage (deals 70% damage to minions) and slowing the movement speed of enemies struck by 40 / 45 / 50 / 55 / 60 % for 2 seconds. The damage increases as the cask ferments, up to 150% over 2 seconds.

Barrel Roll: This can be a very strong poke ability, you'll want to be using this a lot in lane, and remember it slows their movement speed as well. Also, if you wait two seconds it does extra damage, but you usually won't have the opportunity do this in lane, unless of course you CC chain with a jungler on a gank, but keep this in mind for team fighting. This ability also grants sight of the area, so you can use it to scout bushes. Another important thing to mention with this ability is that it can be great for wave clearing so use that to your advantage when you can.

Drunken Rage

Range: N/A
Cooldown: 5
Cost: 30

Gragas takes a long swig from his barrel, disabling his ability to cast or attack for 0.75 seconds and gaining 10 / 12 / 14 / 16 / 18% (+4% per 100 ability power) damage reduction for 2.5 seconds. Upon finishing his drink, Gragas' next attack within 3 seconds and will gain 50 range and deal 20 / 50 / 80 / 110 / 140 (+50% of ability power) (+8% of target's maximum health) bonus magic damage (Max. 300 damage against monsters) in a 250 unit radius area.

Drunken Rage: This can be a pretty useful ability, and has many effects. It's a good idea to use this ability before you use your Body Slam(E), as it has a 1 second channel. This ability is also useful for activating your passive, since it's only 30 mana. This can also be used as decent wave clear, since it has slight area of effect damage. This ability also grants you some damage reduction for 2.5 seconds, so you can time this ability to absorb some damage. Another nice thing about this ability is it does 8% of their max health, so it will always do a decent amount of damage against tanks. This ability can also be used as a pretty good zoning tool in lane, when you see one of your minions getting low and you know they have to come up to last hit it just cast Drunken Rage(W) and try to hit them with it, since it's such low mana you don't really lose much.

Body Slam

Range: 600
Cooldown: 16 / 15 / 14 / 13 / 12
Cost: 50

Gragas charges forward, colliding with the first enemy unit. He deals 80 / 130 / 180 / 230 / 280 (+60% AP) magic damage to enemies in the area and bumps them back, stunning them for 1 second.

Body Slam's cooldown is reduced by 3 seconds if Gragas collides with a unit.

Body Slam: This is a very good ability to setup other abilities, and is especially useful late game since you can use Body Slam(E) and then Flash to catch people out. Remember you can use this ability to escape as well, and it also counts as a knock up for a Yasuo ult. This ability has slight aoe as well, but the width really isn't that big, so the best use of this ability is E'ing, and using your Flash on top of one of their carries; they won't be able to react to this 90% of the time, making it a free stun. Using this effectively is going to take a little bit of practice, and requires knowing the exact range of Body Slam(E). I have seen a few people mess this one up, and it's really bad if you miss it, but insanely good if you hit it. Basically, it's high risk / high reward, but once you have it down it should be second nature.

Explosive Cask

Range: 1150
Cooldown: 120 / 100 / 80
Cost: 100

Gragas throws his cask to a location, which explodes on impact, dealing 200 / 300 / 400 (+70% of ability power) magic damage to all units struck, knocking them back.

Explosive Cask: This can be a very game changing ability depending on the circumstance. Simply speaking, you can use this to knock enemies into you, as well as knock the team off your carries, but it can be used in many other ways. This ability has a little bit of travel time though, so it's going to take some time to get good with, but it can be a straight up game changer because of how many different ways you can use it. I usually use it to engage or catch somebody out, and then Body Slam(E) into them for the lock down, but don't be afraid to use it to save a teammate in danger.

Ability Sequence

> > >


Laning phase is really fun with gragas, since, unlike most tanks, I think you win a lot of match ups. You want to use Barrel Roll(Q) to poke as much as you can, and try to go for Drunken Rage(W) auto attacks when they go for minions.

Gragas also has very good wave clear since all of his abilities are AOE, so use this to your advantage when you need to push.

Gragas actually does very well against ganks, as you can just use Barrel Roll(Q) to slow them, and then Body Slam(E) away. If they extend to far, you use Explosive Cask(R) to force them into your turret and pick up a kill or two. I've gotten many double kills just by doing this. You can also use Explosive Cask(R) to push them away and then Body Slam(E) if you need to.

In general, laning as Gragas is very solid since he has a reliable poke and has mobility, while also having sustain from his passive to out-lane your opponent.

In my experience, Gragas has insane teamfight potential due to his Body Slam(E) + Flash combo, as well as because of how much a well placed ult can impact the teamfight.

Try to focus on peeling for your team, unless you can get a catch on one of their carries with your Flash and Body Slam(E), or if you think you can get a good Explosive Cask(R). Although sometimes people will just Flash your Explosive Cask(R), so keep that in mind.

If they have a comp that is very all-in, or dives your backline, then it's your job to peel with Explosive Cask(R) and Body Slam(E).

If you have a Yasuo on your team then you can also try to go for a huge Explosive Cask(R) for that wombo combo.

I usually play gragas as a huge annoying wall that peels super hard for his team, so don't be afraid to try the same.

Gragas, in my opinion, is a very fun mobile tank. He can do surprisingly well in lane, while also transitioning very well into late game; that is, as long as you're able to hit your abilities and know when to use them.

In my experience Gragas feels like Pre-7.9 Maokai did, except he requires a little bit more skill, does better in laning phase, and features a *way* more impactful ult. Beyond that though, I think these two champions have a lot of similarities, so if you enjoyed pre 7.9 Maokai, I figure that you'll like Gragas.

If you like playing tanks, but don't think they have a lot impact, then you should give Gragas a try; He can change the game with his ult, and also get picks late game with his Flash + Body Slam(E) combo to lockdown a carry. I have had plenty of teamfights where I completely changed the encounter with my Explosive Cask(R). To be honest, I think it's one of the most impactful abilities in the game currently, so I think most people should atleast try him out.
