Hello, I am BMac and this is my AP Jungle Gragas guide! I don't think AP Gragas is any more op than tank, it is just different and Gragas's kit in general is op, doesn't matter how you build him. I mostly play Blind Normals and get matched up with people from gold - plat, I am not claiming this to be a high elo guide. I have seen much success with this pick and have been able to carry dozens of games. It is fun and throws many people off guard.

It is fun to 100 - 0 people using your fat and alcohol.

I don't often play ranked but I play blind pick normals and get matched up with players from Gold to Plat area and I often find success. The best time to pick AP Gragas is when you already have a front line and the enemy team has low mobility carries. But I pick him in all cases and usually can find success

Early Game

Early game AP Gragas isn't much different than tank gragas, do your clear look for ganks.

Mid Game

Once you have Runeglaive and maybe a pen Item or 2 is when Gragas's Damage starts to stand out and is his biggest power spike, use this to create picks with ult and flash body slam and creating skirmishes with a teammate at this point 1 rotation of spell should be able to just about 100 - 0 carries but you may need a teammates help, or one more spell to finish them off. when in a skirmish ping the target you are going for to make sure your teammates know who you are going for.

Late Game

Late game you are an assassin stay on the sidelines of teamfights and hunt your prey, when you see the opportunity to blow someone up, go in with your combo and 100 - 0 them. Hopefully with the chaos of the teamfight you will be able to get out, but you may die afterwards but as long as you killed a carry it is ok, you most likely did massive damage with your ult to other opponents in the process. You can use your ult to engage, disengage, or peel but keep in mind you have significantly less damage without it and your 100 - 0 potential is gone.

Main Burst Combo

Channel W - E towards target(E + Flash if necessary) - Empowered auto - Spam Q on top of the target, pop it instantly - R for final blow.

Pick With ult Combo

Channel W - R target towards you - E towards them - Empowered auto - Spam Q on top of the target, pop it instantly.

Make sure you land your E. It is important to land your E so the opponent does not have time to escape the rest of your combo due to them being stunned.

Choose fights carefully. AP Gragas is squishy and all in, once you use E there is no getting out.

Use W first in Combo. If you use your W after you E someone your stun will wear out and they can escape. it is also a slower burst.

Pop Q before using R. Do not ult them off of your Q before you get the Damage from it. When ulting for the final blow, try to position the ult so that if they don't die you still ulted them towards yourself and you team.

Use E + Flash. Using flash during your E on Gragas is extremely useful it greatly extends the range on your E and makes it almost impossible to dodge.

If the game is going bad go tank. If you don't seem to be able to get the picks early and are just straight up feeding don't be afraid to start to be a tank. Gragas is obviously a great tank.
