Drunken Rage synergizes well with Happy Hour because of the low mana cost and cooldown. You can use this to engage in 1 on 1 fights effectively.
Body Slam is a good first ability to use when initiating a teamfight or when ganking an enemy champion; it will charge to the enemy and stun them for 1 second.
LoL Gragas players will likely find him to be a dynamic character to build out properly. You'll find that his build changes when he is up against either generic or highly focused team comps, indicating you should not select the same Gragas build every round of League of Legends
The most critical items to include in your champion's build include: Everfrost, Rabadon's Deathcap, and Zhonya's Hourglass. Those who included these items in their kits had a much higher win rate than players who tried for other Gragas builds. Similarly, if you are trying to beat a mixed enemy team arrangement, you should really consider grabbing Gragas the Sorcery, and Inspiration runes. In recent games, he won the largest fraction of his matches when using these runes.
