This gragas build has alot of AP with some survival items. With this build in team fights u will nuke down the whole team. the survival items are bc the other team will most likely focus you down and for the AP well i think you know how gragas is with his abilities LOL...

I go with spell pen marks to nuke them better. Health per lvl quint and seals bc bc of gragas passive. Then AP per lvl glyph. the reason i get per lvl instead of straight up runes is bc ur soloing so u lvl faster so it will help more end game.

Masteries i go 9-0-21 in offensive i go into the spell pen bc its very important for gragas well any caster. Then i go down into the utility to help me lane longer.

Boots obviously have to be spell pen u could go CD reduction if they dont go magic resist. Majai's is obvious if you dont fail you will get stacks and roll on the other team. Rod of ages is both Offensive and Defensive stacks alot of health and mana also with 80 AP. Rylai's is also both with more health and AP then the slow is very nice when ur hitting the whole team with barrels. Next is the DEATHCAP i really dont need to explain lol. the last item is kinda what u like GA if they focus u down, Void staff if they go resist...

I lvl my Q most bc it helps for when your jungler comes to gank. W is second bc as a solo lane u dont want to recall so u will need the mana. then my E is at lvl 4 bc thats when ur jungle should be ganking ur lane. your E helps u get to them and slows them.

I like flash ghost they both just help you in almost any situation. Other summoner spells id use would be tele so u can get an early buy in and get to ur lane fast or get to another lane to help. Clarity to help u with ur mana problems

Pros/ amazing farmer and pusher... Great for team fighting damages other team alot...E is amazing to run away in the jungle can jump there most walls... EVERY fun to play as :)

Cons/ Ap gragas gets focused alot... when solo laning sometimes u push to much and can get ganked easy so keep ur flash and E up...
