ESO Poison-Making For The Savvy Assassin

A common expression heard in taverns is “Pick your poison…”. With this guide, a savvy assassin will be able to pick the right poison for the job or to satiate the saltier clients with a need for increased suffering of the victim.



This tome reveals the mysteries of alchemy in the context of poison-making.  Here’s a summary of the highlights:

  • Poisons can be made in batches of up to 16
  • When slotted, poisons suppress weapon enchantments.
  • Poisons have a 10 second cooldown
  • The rank or level of the poison determines the duration if there is an overtime effect, otherwise, the effect is increased.
  • Some potions offer benefits to the user in addition to negative effects to the victim.
  • Stun effects have shorter durations. Some poison provide benefits to the user.

  2. Rank Durations
  3. Traits


Poisons are made in batches of 16 when the alchemy passive Chemistry is maxed.  When slotted on a weapon, their effect overrides the weapon’s enchantment (if one is present). The Rank of the potion will determine the duration of the effect or the intensity of the effect. All Poisons are applied 20% of the time on Light Attacks, Heavy Attacks, or Weapon Abilities.  Oils are found on the tougher mobs, including ogres, trolls, giant snakes, and daedra.
