Earns extra gold from unit kills and bounty runes.
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, he infuses his partner's weapons with Corrosive Substances and created toxic Sludge Acids to accelerate his Greevil's Greed — extracting extra gold from creeps and Bounty Rune minimap icon Bounty Runes. With enough resources, it is rumored that Razzil has the secret formula to Synthesize a buff into the body that equals the legendary scepter. 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 with an Unknown Potion, inducing a Chemical Rage in the ogre's body. Symptoms include unnatural speeds, rapid health regeneration, and a pleasant purple hue.

Bio[]

Alchemist minimap iconRazzil 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.

Undispellable
Using traditional Alchemy from the Darkbrew family, Razzil concocts an acid that dissolves even the toughest metals.

  • Both the armor reduction and ally armor increasing bonus are provided by an aura, its debuff lingers for 0.5 seconds.
    • The damage is independent of the aura, and the damage of multiple instances of Acid Spray fully stacks.
    • However, the enemy armor reduction and ally armor bonus value does not.
  • Deals damage in 1-second intervals, starting immediately upon cast, resulting in up to 16 instances.
  • 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.
    • TALENT
      The armor reduction notes fully apply to the ally armor bonus Talent talent.

  • The stun duration starts at 0.25 seconds and increases by 0.029/0.039/0.049/0.059 for each 0.1 seconds brewed, reaching 1.7/2.2/2.7/3.2 in 5 seconds.
  • The concoction first applies the damage, then the debuff.
  • Unstable Concoction always affects a 250 (Talent 375) radius around where it explodes, including when it explodes on Alchemist.
    • When Alchemist dies while brewing, it instantly blows up, damaging enemy units around Alchemist based on the brewed duration.
    • The self-inflicted damage is lethal, it can be used to deny oneself.
  • TALENT

Upgradable by Aghanim's Scepter.
Requires drafting Greevil's Greed icon Greevil's Greed to be unlocked, instead of being innate to Alchemist.
However, Chemical Rage icon Chemical Rage must be drafted as well for the bonus attack damage and bonus spell amplification component to work.

  • This is innate to Alchemist, despite Chemical Rage icon Chemical Rage's in-game ability upgrade tooltip.
  • Aghanim's Scepter icon Aghanim's Scepter has an active ability for Alchemist, allowing him to cast it on ally heroes.
    • Treats clones and illusions as creeps.
    • ↓↓ Double-tapping Aghanim's Scepter in the inventory automatically targets self.
    • Once cast, the Scepter is consumed and the target ally passively receives all of Aghanim's Scepter icon Aghanim's Scepter's upgrades, as well as the item's attributes:
    • The 4200 Gold 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 target ally bought Aghanim's Scepter and has it in their inventory or backpack, it gets refunded, removing it and granting them 4200 Gold.
    • If the target ally already has Aghanim's Blessing icon Aghanim's Blessing or Aghanim's Blessing - Roshan icon Aghanim's Blessing - Roshan 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 target ally by Alchemist, except when targeting himself.
    • Gold refunded this way is granted as unreliable gold.
  • The number of stacks and amount of bonuses gained can be seen on the status buff icon. Grants the following bonuses to Alchemist upon cast on ally heroes:
  • Since up to 4 allies and Alchemist himself can be infused, Alchemist can gain up to 125 attack damage and 25% spell damage amplification bonus.

Trivia[]

  • 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 icon 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 icon Acid Spray's ▶️ sound effect has the same reprocessed sound of ▶️ Oil Platform building from game Warcraft 2: Tides of Darkness, created by Blizzard.
  • ▶️ "Only ninety-eight percent pure?" is a direct reference to AMC's TV series Breaking Bad.[1]
  • ▶️ "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.
  • When activating Haste Rune minimap icon 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]
  • ▶️ " 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.
