Annie releases her bear Tibbers from his toy prison, dealing 150 / 275 / 400 (+65% of ability power) magic damage to enemy units in the summon area. For the next 45 seconds, Tibbers can move and attack at Annie's will, while continually dealing 10 / 15 / 20 (+10% of ability power) magic damage to surrounding enemies.

Tibbers has 1200 / 2100 / 3000 health, 30 / 50 / 70 armor and magic resist and deals 50 / 75 / 100 (+15% of ability power) magic damage per auto attack.

On summon, using Pyromania on an enemy champion or if Annie dies while Tibbers is summoned, Tibbers becomes enraged, ignoring unit collision and gaining 275% bonus attack speed and 100% bonus movement speed which decays over 3 seconds. In addition, Tibbers regenerates 50% of his missing Health and automatically targets Annie's killer if she dies while he's summoned.

While out of combat for at least 5 seconds, Tibbers gains movement speed when moving toward Annie and regenerates 6.0% of his maximum Health every second.
