Razzil Darkbrew, the Alchemist, is a melee strength hero whose alchemical prowess makes him a strange but versatile fighter. He is an unusual carry based upon transmuting killed creeps into large amounts of bonus gold, with both an early game and late game presence due to the enormous health regeneration from his ultimate and the first strike nature of his other spells. His low but balanced attributes and the sure promise of gold for items means he can be one of the most disparately built heroes in the game.

Unstable Concoction is his main contribution early on, dealing good damage and a lengthy stun. Acid Spray allows him to rapidly clear waves of creeps for his Greevil's Greed to contribute massive amounts of extra income. A well-equipped Alchemist can then use Chemical Rage to its fullest effect, as the incredible regeneration and base attack time reduction make it one of the best steroid abilities in the game.


Alchemist minimap icon.pngRazzil Darkbrew, the Alchemist
▶️ "Failure is just another kind of success. The wrong kind."
The sacred science of Chymistry was a Darkbrew family tradition, but no Darkbrew had ever shown the kind of creativity, ambition, and recklessness of young Razzil. However, when adulthood came calling he pushed aside the family trade to try his hand at manufacturing gold through Alchemy.

In an act of audacity befitting his reputation, Razzil announced he would transmute an entire mountain into gold. Following two decades of research and spending and preparation, he failed spectacularly, quickly finding himself imprisoned for the widespread destruction his experiment wrought. Yet Razzil was never one to take a setback lightly, and sought escape to continue his research.

When his new cellmate turned out to be a fierce ogre, he found just the opportunity he needed. After convincing the ogre not to eat him, Razzil set about carefully concocting a tincture for it to drink, made from the moulds and mosses growing in the prison stone work. In a week's time, it seemed ready. When the ogre drank the potion, it flew into an unstoppable berserker rage, destroying the cell bars and exploding through walls and guards alike.

They soon found themselves lost somewhere in the forest surrounding the city with a trail of wreckage in their wake and no signs of pursuit. In the tonic's afterglow, the ogre seemed serene, happy, and even eager. Resolving to work together, the pair set off to collect the materials needed to attempt Razzil's Alchemic transmutation once more.

  • When leveling up the ability while a cast is already active, the armor reduction value on already affected units does not update to the new value.
    • However, if an enemy receives the debuff after leveling it up, that enemy receives the new armor reduction value.
    • The damage value does not update and is always based on the level the ability was cast on.
  • The damage of multiple instances of Acid Spray fully stacks. However, the armor reduction does not.

Unstable Concoction

However, after 5.5 seconds, the concoction will explode on Alchemist himself if not thrown.

This ability is bound to Greevil's Greed, instead of being innate to Alchemist.


  • This is an innate ability.
  • Aghanim's Scepter icon.png Aghanim's Scepter has an active ability for Alchemist, allowing him to cast it on allied heroes (excluding hero clones and illusions).
    • Once cast, the Scepter is consumed and the targeted ally passively receives all of Aghanim's Scepter icon.png Aghanim's Scepter's effects.
    • ↓↓ Double-tapping Aghanim's Scepter in the inventory automatically targets self.
    • This includes all Aghanim's Scepter upgrades, as well as the item's attributes, 10 Strength attribute symbol.png strength, 10 Agility attribute symbol.png agility, 10 Intelligence attribute symbol.png intelligence, 175 health, and 175 mana.
    • The net worth of the item transfers from Alchemist to the target hero. Self-casting does not change the net worth.
    • Doing so does not change Alchemist's or the target's GPM.
    • A hero can only be targeted once by Aghanim's Scepter Synth.
  • If the targeted ally already bought Aghanim's Scepter and has it in their inventory or backpack, it gets refunded, removing it and granting them 4200 Gold.
    • If the targeted ally already has Aghanim's Blessing icon.png Aghanim's Blessing consumed, it gets refunded as well, granting them 5800 Gold.
    • It does not matter how the target acquired Aghanim's Blessing, the gold is always refunded to the player targeted by Alchemist.
    • It also grants gold for the Aghanim's Blessing acquired from Roshan icon.png Roshan.
  • Alchemist has to infuse himself with an Aghanim's Scepter for the bonuses to take into effect.
    • Since up to 4 allies and Alchemist himself can be infused, Alchemist can gain up to 100 attack damage and 25% spell damage amplification.

Playstyle: Having broken out of prison with his ogre accomplice, Razzil Darkbrew embarks on the search for new materials to use in his transmutations. Learned in alchemy, Razzil is able to extract extra gold from creeps, and create fields of toxic sludge with Acid Spray. The Alchemist brews, atop the shoulders of his companion, an increasingly Unstable Concoction that is ideally thrown before it explodes. In a pinch, Razzil slips his partner an unknown potion, inducing a Chemical Rage in the ogre's body. Symptoms include unnatural attack speed, rapid health regeneration, and a pleasant purple hue.





  • At one point during beta, Alchemist's bio consisted entirely of the following sentence: "Alchemist is named Al and is a chemist."
  • Alchemist's third ability name remained unchanged from its DotA counterpart until after the Diretide event, when it was changed from "Goblin's Greed" into "Greevil's Greed."
  • The Ogre's portion of the Caustic Steel cosmetic set may be a reference to Master Blaster from Mad Max: Beyond The Thunderdome, while the Alchemist's armor and hair are most likely a reference to Edward Elric, one of the two main protagonists of Fullmetal Alchemist.
  • Acid Spray's ▶️ sound effect has the same reprocessed sound of ▶️ Oil Platform building from game Warcraft 2: Tides of Darkness, created by Blizzard.
  • One of Alchemist's last hit lines ▶️ "Only ninety-eight percent pure?" is a direct reference to AMC's TV series Breaking Bad.[1]
  • Another of his last hit lines ▶️ "Greed is good." is a reference to Gordon Gekko's speech in the 1987 film, Wall Street.[2] as well as the actual cheat code from Warcraft III which gives the player gold on single player campaign.
  • Alchemist's line for picking up a Haste Rune minimap icon.png Haste Rune ▶️ "Run, buddy, run!" may be a reference to Forrest Gump, since sometime in the movie there is a line "Run, Forrest, Run!"[3]
  • Alchemist's leveling line ▶️ " Better living through alchemy!" is a reference to the phrase "Better Living Through Chemistry", a popular variant of a DuPont advertising slogan which later became a common phrase.
