After casting a spell, for 3 seconds Alistar ignores unit collision and deals 6 + (1 × level) (+ 10% AP) magic damage to nearby enemy units and structures each second. Trample deals double damage to minions and monsters, dealing 12 + (2 × level) (+ 20% AP) damage per second.
If you select to attack your target prior to using Headbutt, Alistar will automatically and immediately attack after colliding with almost not attack wind-up. This interaction makes spellblade items particularly potent on Alistar.
Cost: 40 / 50 / 60 / 70 / 80 mana
Active: Alistar heals himself, with nearby allies healing for half that amount. Triumphant Roar's cooldown is reduced by 2 seconds whenever a nearby enemy unit dies.
