Alchemist Alchemist is a formidable carry capable of amassing large amounts of gold, and sustaining himself almost indefinitely during teamfights. Armed with a Shadow Blade icon.png Shadow Blade, Alchemist can also gank effectively by stunning enemies with Unstable Concoction icon.png Unstable Concoction. Because of the extra gold from his Greevil's Greed icon.png Greevil's Greed, Alchemist will always snowball into a potent fighter if a match goes long. Under Chemical Rage icon.png Chemical Rage, a well-farmed Alchemist can demolish heroes and structures alike with alarmingly fast attack speed, all the while regenerating his health at incredible rates.
Pros Cons
  • Scales well into late game.
  • Good comeback potential.
  • Capable of farming gold quickly.
  • Highly reliant on his ultimate.
  • Vulnerable to disables.
  • Worst attribute growth in the game.


Alchemist is usually played as a carry. This build requires him to level Greevil's Greed, thus allowing him to quickly farm key items like Armlet of Mordiggian (Inactive) icon.png Armlet of Mordiggian or Radiance (Active) icon.png Radiance. Acid Spray is also leveled early to aid in clearing creep waves, especially if Alchemist goes solo in lane. A successful player aims to overwhelm the opposing team during the mid game, when Chemical Rage makes Alchemist extremely hard to kill.


Alchemist is sometimes played as a support. This build requires him throw out stuns with Unstable Concoction, and zone out enemies with Acid Spray. A support Alchemist is expected to purchase wards. Due to the extra gold from Greevil's Greed, support Alchemists can still transition into damage dealers in the late game. Some players may opt to farm an Aghanim's Scepter icon.png Aghanim's Scepter for their teammates, but this is not a common strategy.

Tips & Tactics[edit]


  • Alchemist is a fairly heavy carry, but may still have trouble dealing with other hard carries, such as Spectre Spectre.
  • Alchemist farms faster than any other hero, thank to Greevil's Greed.


Acid Spray icon.png Acid Spray[edit]

  • Use Acid Spray to farm in lane if your opponents are harassing you heavily.
  • Acid Spray is useful in farming creeps. Ask a support to stack camps for you.
    • It is possible for Alchemist to farm ancient creeps safely early on with Acid Spray. Combined with Greevil's Greed, this can give Alchemist incredible amounts of gold over time. It is not uncommon to have expensive items like Radiance (Active) icon.png Radiance or Mjollnir icon.png Mjollnir by 14 minutes with this strategy.
    • Acid Spray can also be used to stack creeps from a distance. Using it on creeps will cause them to automatically pursue Alchemist, and therefore move away from the camp.
  • Use Acid Spray to dissuade enemies from defending their towers, or pushing into yours.
  • If playing mid, use Acid Spray to push the wave before you pick up the rune every two minutes.

Unstable Concoction icon.png Unstable Concoction[edit]

  • One point in Unstable Concoction is usually enough until other abilities have been leveled.
  • Smart opponents can make it difficult to land Unstable Concoction by juking and avoiding your vision, causing the backfire. It may be better to use it immediately when an enemy reaches the treeline, even if you lose damage and stun duration.
  • Enemies will attempt to disable Alchemist while Unstable Concoction is brewing, preventing him from throwing it and causing him to suffer a long stun in addition to the first enemy disable. Try to stay out of reach until you are ready to throw Unstable Concoction.
  • Fully brewed, Unstable Concoction is one of the most potent stuns in the game, in both damage and stun duration. The enemy is able to see your timer. It is imperative that you either start channeling within range, or channel a few seconds of the concoction from within fog before revealing yourself. This ability is most devastating to low armor heroes that almost take its full damage upon impact, especially if they are softened up by Acid Spray.
  • If you are in a tight spot and have no way to escape with low health, Unstable Concoction can be used to deny yourself.
  • It may not be a good idea to charge Unstable Concoction if you believe you are about to lose vision of an enemy (such as when chasing through trees), as you could end up stunning yourself.
  • Begin charging Unstable Concoction before using Shadow Blade icon.png Shadow Blade or Silver Edge icon.png Silver Edge to take enemies by surprise.
  • Unstable Concoction can be used to deny yourself. If you find yourself in a sticky situation with Chemical Rage on cooldown and no means of escape, you can channel this spell in the hopes of denying yourself.

Greevil's Greed icon.png Greevil's Greed[edit]

  • An early point significantly increases Alchemist's gold income.
    • Putting your first skill point into it can gain you a 150 gold advantage if your team can secure the Bounty Rune minimap icon.png Bounty Rune on your side of the map. You may even be able to double it if you can get both Bounty Runes on your side of the map.
      • If you are feeling particularly lucky or daring, you can try to steal the Bounty Runes on your opponent's end before claiming the runes on your side of the map.
      • Don't be too quick to learn this skill immediately when the match starts. You should invest the your first point into this skill only if you can guarantee that you will claim the rune, as if your teammates or opponents happen to steal it from you, you will be at a severe disadvantage during the early laning stages, as Alchemist's melee range, poor damage and attack speed makes it difficult for him to last-hit effectively.

Chemical Rage icon.png Chemical Rage[edit]

  • Chemical Rage disjoints projectiles, but can be difficult to time properly.
  • Feel free to use Chemical Rage for its healing effects; it even regenerates its own mana cost over the duration, and even more if you have percentage bonuses for mana regeneration from items like Sage's Mask icon.png Sage's Mask or Perseverance icon.png Perseverance.
  • When Chemical Rage is on cooldown, Alchemist is extremely squishy due to his poor strength gain and low armor.
  • Chemical Rage is the strongest single target DPS booster in the game (giving a 70% boost in DPS at level 3). This means that Alchemist scales very strongly with attack damage boosting items, however at the same time Alchemist does very little damage without such items. This means if Alchemist is going to contribute into team battles down the road, it is imperative to get yourself some attack damage.
  • It is important to understand that the Base Attack Time change of Chemical Rage does not alter the value of attack speed, neither up nor down. You still want to have a good mix of items that give attack speed and damage.
  • Chemical Rage's health regeneration is further amplified by a percentage based on Alchemist's Strength attribute symbol.png strength attribute. As such, high strength items such as Satanic icon.png Satanic or Heart of Tarrasque icon.png Heart of Tarrasque will significantly boost his HP regeneration when Chemical Rage is active.


Starting items:

Early game:

Core items:

  • Phase Boots icon.png Phase Boots gives a damage boost and the phase active works well with Chemical Rage movement speed bonus to chase opponents.
  • Armlet of Mordiggian (Inactive) icon.png Armlet of Mordiggian is useful on Alchemist because Chemical Rage health regeneration counters the item's health draining effect.

Situational items:

  • Boots of Travel 1 icon.png Boots of Travel allows Alchemist to split push lanes, and be present at while farming free lanes. Also, the movement speed boost greatly mitigates his weakness in mobility.
  • Black King Bar icon.png Black King Bar allows Alchemist to be uninterrupted in his attacks.
  • Radiance (Active) icon.png Radiance is a good pickup since Alchemist can get it very quickly with Greevil's Greed, when the burn damage hurts the most. It can also deal heavy damage to the enemy team, as Alchemist can stay alive for prolonged periods with Chemical Rage.
  • Manta Style icon.png Manta Style is excellent for sieging buildings, and also provides Alchemist with a much needed disjoint mechanism.
  • Octarine Core icon.png Octarine Core lowers cooldown to allow longer uptime of Chemical Rage; the spell lifesteal allows Alchemist to gain back some health with Acid Spray and Radiance.
  • Shiva's Guard icon.png Shiva's Guard grants tankiness with armor and attack speed slow aura. Arctic Blast also slows enemy movement speed, keeping them in range of Acid Spray and Radiance.
  • Assault Cuirass icon.png Assault Cuirass lowers enemies' armor, which stacks with the armor reduction from Acid Spray. It also provides a useful aura to buff armor and attack speed the rest of your team.
  • Mjollnir icon.png Mjollnir increases Alchemist's attack speed greatly, and also gives a useful Static Charge to protect Alchemist or his teammates. Its lightning attack will also trigger often under Chemical Rage.
  • Battle Fury icon.png Battle Fury allows Alchemist to farm anything in no time, also you can farm it within 6 minutes with Battle Fury you can get Aghanim's Scepter for all your team.
  • Vladmir's Offering icon.png Vladmir's Offering provides a useful aura and uses a Ring of Basilius (Active) icon.png Ring of Basilius as one of its components.
  • Blade Mail icon.png Blade Mail forces enemies to think twice about fighting back against Alchemist.
  • Abyssal Blade icon.png Abyssal Blade goes well with Alchemist's high attack speed, and helps greatly in securing an enemy. It also gives bonus attack damage and greater survivability providing bonus HP and blocking damage from incoming attacks.
  • Heaven's Halberd icon.png Heaven's Halberd gives some strength and evasion, and also gives the ability to disarm a threatening enemy.
  • Heart of Tarrasque icon.png Heart of Tarrasque gives Alchemist a massive amount of health. Combined with the health regeneration from Chemical Rage, Alchemist is extremely hard to take down.
  • Solar Crest icon.png Solar Crest allows Alchemist to further reduce the armor of his enemies, makes it easier to fight them with his Ultimate, and allows him to further support allies.
  • Shadow Blade icon.png Shadow Blade grants Alchemist invisibility to brew up his Unstable Concoction. He can break the invisibility by attacking the enemy for additional bonus damage and at the same time launch his concoction. You can upgrade to Silver Edge icon.png Silver Edge for the break effect.
  • Moon Shard icon.png Moon Shard serves as a cheap, permanent upgrade to Alchemist without using any inventory slots. He can also use Moon Shard on an ally to give them the bonus attack speed instead.
  • Aghanim's Scepter icon.png Aghanim's Scepter allows Alchemist to give the item to an ally, granting them appropriate upgrades and attributes.
