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 Razzil Darkbrew, the Alchemist
Play "Failure is just another kind of success. The wrong kind."
Lore: 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.

Acid Spray icon.png
Sprays high-pressure acid across a target area. Enemy units who step across the contaminated terrain take damage per second and have their armor reduced.
Cast Animation: 0.2+0.7

Mana symbol.png 130/140/150/160
Debuff Acid Spray: Undispellable.
Using traditional Alchemy from the Darkbrew family, Razzil concocts an acid that dissolves even the toughest metals.


  • The armor reduction is provided by an aura. Its debuff lingers for 0.5 seconds. The damage is independent from the aura.
  • Deals damage in 1-second intervals, starting 1 second after receiving the debuff, 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.
  • The damage of multiple instances of Acid Spray fully stacks. The armor reduction, however, does not.

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

A silver lining to the failure of turning a mountain into gold, this volatile solution has destructive potential.

  • The stun starts at 0.3 and increases by 0.029/0.044/0.059/0.074 for each 0.1 seconds brewed, reaching 1.75/2.5/3.25/4 in 5 seconds.
  • The concoction first applies the damage, then the debuff.
  • Unstable Concoction always affects a 200 area around where it explodes, including when it explodes on Alchemist.
  • When Alchemist dies while brewing, it instantly blows up, hitting units around Alchemist based on how long it was brewed.
  • While brewing the concoction, Alchemist can still move around and act freely.
  • The stun and damage can hit creep-heroes within the radius as well.

Aghanim's Scepter ability icon.png
Alchemist melts down Aghanim's Scepter to grant an allied hero all Aghanim's Scepter upgrades.
Cast Range: 600
Partially usable by illusions. Illusions copy the buff and gain the upgrades as well, but do not gain the attributes, health and mana bonus from the buff.
Buff Ultimate Scepter Consumed: Undispellable.


  • 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 destroyed and the targeted ally receives the Ultimate Scepter Consumed buff, which is permanent.
    • This status buff grants the ally the same stats as an Aghanim's Scepter and fully applies any Scepter upgrades on the hero.
    • Alchemist can cast Aghanim's Scepter on himself as well, gaining the stats only, since he has no upgrades.
    • The net worth of the Scepter transfers from Alchemist to the target hero. Self-casting does not change the net worth.
    • Doing so does neither change Alchemist's nor the target's GPM.
    • A hero can only be targeted once by Aghanim's Scepter.
  • The ability to transfer Aghanim's Scepter is innate to the hero and not the ultimate ability.
    • This means that Alchemist can share Aghanim's Scepters in Ability Draft, regardless of his skills.

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.
