Caitlyn

P / Triumphant Roar

Alistar charges his roar by stunning or displacing enemy champions or when nearby enemies die. When fully charged he heals himself all nearby allied champions.

Q / Pulverize

Alistar smashes the ground, dealing damage to nearby enemies and tossing them into the air.

W / Headbutt

Alistar rams a target with his head, dealing damage and knocking the target back.

E / Trample

Alistar tramples nearby enemy units, ignoring unit collision and gaining stacks if he damages an enemy champion. At full stacks Alistar's next basic attack against an enemy champion deals additional magic damage and stuns them.

R / Unbreakable Will

Alistar lets out a wild roar, removing all crowd control effects on himself, and reducing incoming physical and magical damage for the duration.

Riot's tips against Alistar

• Alistar is very disruptive but very tough - try to target more fragile damage dealers.
• Watch out for the Pulverize-Headbutt combo when around turrets.
• When Alistar uses his ultimate, it's often better to move back and wait until the effect wears off before attacking him.
