Alchemist brews up an unstable concoction that he can throw at an enemy hero, to stun and deal damage in an area around the explosion. The longer the concoction brews, the more damage it deals and the longer the stun. After 5 seconds, the brew reaches its maximum damage and stun time. However, after 7 seconds, the concoction will explode on Alchemist himself if not thrown.
Alchemist gets bonus gold for killing creeps; the bonus stacks if the creeps are killed within a period of time, after which the count is reset. The bonus gold is capped at 30 gold.
Alchemist causes his Ogre to enter a chemically induced rage, reducing base attack cooldown and increasing movement speed, hitpoints and regeneration.
