Toxic Mist is a pyromancy in Dark Souls III.

In-Game Description

Unique pyromancy of Eingyi that never gained currency in the Great Swamp.
Creates an intense poison mist.
Driven from the Great Swamp, they say that at the end of his journey, Eingyi happened upon a virulent poison and a young lady.


Found in the Smouldering Lake, on a corpse in a lava pool located behind an illusory wall in a room with three Hound Rats in it. After the exit to the right in the hallway with the Smouldering Ghru, it will be down some stairs on the left-hand side and is found on the visible first corpse.

In order to survive the trip inside the lava, there are many strategies that can be followed and combined before venturing inside. The main idea is to slow down the loss of HP enough to allow the player to heal and advance a bit further, until they have successfully retrieved the item and returned to solid ground.

Possible survival techniques include:


When cast, a toxic cloud is released in front of the caster, causing gradual Toxic buildup to foes that stand in it. Once contracted, Toxic causes 10 damage per second for the duration.

Buildup is static and is not affected by rings or spell buffs.


  • The virulent poison and young lady that Eingyi encountered are likely the blight pus and Quelaag's Sister, respectively.
