 * greatly reduces Chemical Rage's attack speed advantage.


 * - Invoker can win the mid lane easily against Alchemist because regeneration will nullify Acid Spray's damage over time and  damage bonus will allow Invoker to out last hit Alchemist.

 * Chemical Rage will rarely save Alchemist against Ursa's.


 * Ember's magic damage build is able to burst down Alchemist due to his low strength gain and Alchemist's normal item pick up.


 * A good timing of is able to save Juggernaut himself from Alchemist's Unstable Concoction, resulting Alchemist himself being stunned by his own medicine.
 * Juggernaut's high attack speed paired up with is a great passive combo to tear down Alchemist in seconds although even if he has activated Chemical Rage to sustain himself battling Juggernaut thanks to his innate disadvantage of low base armor.

Others

 * 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.
 * can take advantage of Alchemist's little armor to kill him.
 * 's 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.
