After using an ability, Alistar stampedes for 3 seconds, ignoring unit collision and dealing 6 + (1 × Alistar's level) (+10% AP) magic damage per second to nearby enemy units and structures (200% damage against enemy 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 roars, healing himself as well as nearby allies for half as much. Triumphant Roar's cooldown is reduced by 2 seconds whenever an enemy dies near Alistar.
