Razzil Darkbrew, the Alchemist, is a premier Strength-based carry and flash-farmer in DotA 1, uniquely defined by his ability to accelerate his net worth far ahead of any other hero. Combining balanced baseline attributes with unparalleled financial manipulation, Alchemist can easily shrug off a difficult laning phase. By melting enemy armor, preparing volatile explosive mixtures, and chemically mutating his ogre mount into a rapid-attacking engine of massive health regeneration, he quickly scales into an unstoppable frontline juggernaut.

2. Unstable Concoction
Alchemist brews up an unstable concoction that he can throw at an enemy hero, to stun and deal smashing damage in an area around the explosion. The longer the concoction brews, the more damage it deals and the longer the stun. However, after a set duration, the concoction will explode on Alchemist himself if not thrown.
- Damage Type: Smashing (Physical)
- Maximum Brew Time: 5 seconds to achieve maximum damage and stun values.
- Self-Detonation Threshold: 5.5 seconds (explodes on Alchemist, dealing damage and stunning him instead if not launched).

- Duration: 25 seconds
- Dispel Conditions: Applies a basic dispel upon activation, stripping away minor debuffs and slows.
- Projectile Disjoint: Instantly breaks the tracking of incoming attack and spell projectiles upon activation.

Item Build Guide
| Phase |
Recommended Items |
Strategic Purpose |
| Early Game |
Quelling Blade, Soul Ring, Phase Boots |
Quelling Blade guarantees early last-hits to kickstart Goblin's Greed. Soul Ring provides the mandatory mana engine required to continuously drop Acid Spray in lane or neutral camps, while Phase Boots make up for early movement limitations. |
| Core Items |
Radiance, Black King Bar (BKB), Manta Style |
Radiance is the premier flash-farming tool, burning down entire neutral camps simultaneously to maximize Goblin's Greed stacks. Black King Bar prevents him from being permanently locked down, while Manta Style offers a self-dispel and fast split-pushing potential. |
| Late Game |
Assault Cuirass, Abyssal Blade, Moon Shard |
Assault Cuirass stacks perfectly with Acid Spray's armor reduction while compensating for Alchemist's poor natural Agility growth. Abyssal Blade grants targeted lock-down, and Moon Shard exploits his low 1.0 Base Attack Time to maximize bash potential. |
Quick Gameplay Tips
- The Physical Melt Combination: Both Acid Spray and Unstable Concoction deal Smashing (Physical) damage rather than Magical. Because Acid Spray strips away up to 7 armor at maximum rank, you should always target your concoction projectile onto an enemy standing directly inside the active acid pool. This allows the explosive burst to inflict near-pure damage against melted targets.
- The Art of the 5-Second Brew: To minimize reaction time for your enemies, charge Unstable Concoction while positioned safely out of enemy vision (such as inside the fog of war or high-ground treelines). Begin rushing toward your target when the countdown timer hits 3 seconds, letting you launch the projectile right as it reaches its maximum 4-second stun potential without giving opponents time to run or react.
- Chemical Projectile Disjointing: The transformation animation of Chemical Rage features a split-second window that completely disjoints incoming single-target spells and physical attacks. If an enemy projectile (such as a homing stun or a lethal ranged strike) is flying directly toward you, time the activation of your ultimate perfectly to cause the incoming threat to completely miss.
