Show/Hide Tooltips
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 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

[edit]
Failure is just another kind of success. The wrong kind.
▶️  Razzil Darkbrew, the Alchemist
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.

Trivia

[edit]
  • At one point during beta, Alchemist's bio consisted entirely of the following sentence: "Alchemist is named Al and is a chemist."
  • 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.
  • ▶️ "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 ▶️ "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.
  • Warcraft 3 similarities:
    • Alchemist's hero concept is originally based on the Alchemist, a neutral goblin hero.
      • Acid Spray and Acid Bomb are both AoE abilities that deal damage over time and reduce armor, only their targeting is different.
        • Acid Spray conbines the names of Acid Bomb and Healing Spray, which is another Warcraft 3 Alchemist ability.
      • Chemical Rage is identical to the Warcraft 3 Alchemist's Chemical Rage.
      • Greevil's Greed is inspired by the greediness of the Warcraft 3 Alchemist
        • The ultimate ability of the Warcraft 3 Alchemist is Transmute, which is has the same functionality as Hand of Midas.
    • Unstable Concoction's concept is inspired by the Troll Batrider's ability of the same name, Unstable Concoction.
    • Alchemist's name, Razzil Darkbrew, combines two of six different names the Alchemist in Warcraft 3 can spawn with.
      • The first name is taken from Razzil Naypolm, while the last name is based on Ezzel Darkbrewer.
