Bad against...[]

Ancient Apparition icon.png
  • Ice Blast cancels out Chemical Rage's rapid health regeneration. It can also take advantage of Alchemist's Armlet of Mordiggian (Inactive) icon.png Armlet of Mordiggian toggling, as it will make HP drain insanely fast, essentially killing the bearer in no time.
Enchantress icon.png
  • Untouchable greatly reduces Chemical Rage's attack speed advantage.
Invoker icon.png
  • Quas- Exort Invoker can win the mid lane easily against Alchemist because Quas regeneration will nullify Acid Spray's damage over time and Exort damage bonus will allow Invoker to out last hit Alchemist.
Kunkka icon.png
  • Tidebringer will deal lots of damage to Alchemist before he builds physical survivability items.
  • Torrent and X Marks the Spot can control Alchemist at all stages of the game before he has Black King Bar.
  • Ghostship's rum buff will greatly reduce the Alchemist's damage output in teamfights including his Radiance.
Lifestealer icon.png
  • Feast is good against high health strength heroes such as Alchemist.
  • Rage allows Lifestealer to not be targetable by Unstable Concoction, possibly making Alchemist stun himself.
Necrophos icon.png
  • Reaper's Scythe can kill Alchemist before Chemical Rage has the time to heal him.
  • Ghost Shroud can prevent Alchemist from attacking Necrophos, as well as make him immune to Acid Spray and Unstable Concoction damage.
  • Heartstopper Aura will do damage as long as Necrophos is alive based on health percentage, which is a problem for a strength hero such as Alchemist.
Slardar icon.png
  • Corrosive Haze followed by Slithereen Crush takes advantage of Alchemist's main weakness, being physical damage before he has the change to improve his surviability with items.
  • Bash of the Deep will deal lots of damage during the laning phase.
Slark icon.png
  • Shadow Dance allows Slark to not be targeted by Unstable Concoction, making Alchemist stun himself and making himself vulnerable to the enemy.
  • Dark Pact also allows him to just purge off the stun if timed correctly.
  • Essence Shift will steal stats over long durations at a time should Alchemist lack the damage to kill Slark.
Ursa icon.png
  • Chemical Rage will rarely save Alchemist against Ursa's Fury Swipes.
  • Enrage allows Ursa to both be a threat to Alchemist and avoid his over time damage.
Ember Spirit icon.png
  • Ember's magic damage build is able to burst down Alchemist due to his low strength gain and Alchemist's normal item pick up.
Razor icon.png
  • Alchemist's reliance on fast attack speed to do single-target damage makes him vulnerable to Static Link. It also goes through Black King Bar icon.png Black King Bar, which is a standard item on Alchemist.
  • Eye of the Storm is great against high health strength heroes as it reduces their survivability to physical damage.
  • Razor has early lane push to counter Acid Spray.


  • Viper minimap icon.png Viper can bully Alchemist out of mid lane quite easily, forcing him to either retreat into jungle, or stay harassed in lane, and get very few last hits. Vipers break also completely disables Greevil's Greed which prevents Alchemist to earn his amazing amounts of money.
  • Clinkz minimap icon.png Clinkz can use Burning Army in teamfights which will cause a problem for Alchemist.
  • Pugna minimap icon.png Pugna's Decrepify makes sure that either Alchemist is unable to hit anyone while also being slowed and susceptible to magical damage, or can protect an ally from physical attacks. Besides, Pugna can push early on, when Alchemist is not strong enough to repel it, so by the time Alchemist comes online, he might be forced to sit in base.


  • Assault Cuirass icon.png Assault Cuirass reduces Alchemist's physical survivability and his teammates.
  • Shiva's Guard icon.png Shiva's Guard does the same thing as Assault Cuirass but it also reduces the attack speed, reducing the effectiveness of Chemical Rage.
  • Heaven's Halberd icon.png Heaven's Halberd applies an undispellable disarm so Alchemist cannot attack during Chemical Rage, forcing him to activate Black King Bar beforehand.
  • Scythe of Vyse icon.png Scythe of Vyse disables Alchemist, making sure he won't be able to use his Chemical Rage to heal up, and allows heroes to burst him down fast.
  • Spirit Vessel icon.png Spirit Vessel reduces Alchemist's health regeneration.

Good against...[]

Broodmother icon.png
  • Alchemist can easily farm Spiderlings with Acid Spray and Greevil's Greed.
  • Alchemist's Chemical Rage nullifies Broodmother's Insatiable Hunger
Nature's Prophet icon.png
  • Acid Spray and Greevil's Greed will quickly destroy pushes with treants.
Phoenix icon.png
  • Chemical Rage kills Phoenix very quickly in Supernova.
Undying icon.png
  • Chemical Rage will take down Tombstone in no time.
Huskar icon.png


Works well with...[]

Oracle icon.png


  • Alchemist works well with any hero that benefits from Aghanim's Scepter icon.png Aghanim's Scepter, as he can farm it for them (most likely far more quickly if he has radiance combined with his passive) and also free up an inventory slot.
