Current abilities
Acid SpraySprays high-pressure acid across a target area. Enemy units who step across the contaminated terrain take damage per second and have their armor reduced.
Unstable ConcoctionAlchemist 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. Alchemist is faster while charging the concoction. After 5 seconds, the brew reaches its maximum damage and stun time. However, after 5.5 seconds, the concoction will explode on Alchemist himself if not thrown.
Corrosive WeaponryAlchemist coats his weapons and empowers his spells with an acid that applies a stacking slow and base attack damage reduction to enemies hit. Attacks apply 2 stacks. Unstable Concoction applies 1 stack per second of brew time.
Berserk PotionAlchemist throws a potion at an ally, applying a basic dispel and giving them attack speed, movement speed and HP regen. DISPEL TYPE: Basic Dispel
Greevil's Greed innateAlchemist synthesizes additional gold from his enemies and bounty runes. With each kill, Alchemist earns base bonus gold and extra bonus gold. If Alchemist kills another unit which yields gold within the next 40 seconds, an additional instance of Extra Bonus Gold is added to the total. Additionally, causes bounty runes to yield more gold.
Chemical RageAlchemist causes his Ogre to enter a chemically induced rage, reducing base attack cooldown and increasing movement speed and health regeneration. DISPEL TYPE: Basic Dispel
Unstable Concoction ThrowThrow it before it blows up!
