After casting a spell, for 3 seconds Alistar ignores unit collision and deals 6 + (1 × Alistar's level) (+ 10% AP) magic damage to nearby enemy units and structures each second. Deals double damage to minions.
Prior to patch 4.15 If you selected to attack your target prior to using Headbutt, Alistar would automatically and immediately attack after colliding with almost no attack wind-up. This interaction made spellblade items particularly potent on Alistar however this was removed because the opponent had no way to retaliate.
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.
