Focus ConsumptionFocus Cost 13
Attunement SlotsSlots Used 1
Requirements 30 Intelligence
Type Lingering AoE



Highly dangerous sorcery employed by Dragon School spooks. Only taught to trusted members.

Releases dense mist that eats away at HP. Beware, as the caster is not immune to its effect.

A body caught in the silent mist cloud lies still, while the face twists in a tortured scream. The names of these learned sorcerers became feared for this gruesome spectacle.


Acquired From

  •  Can be bought from Orbeck of Vinheim for 1,000 souls after giving any sorcery scroll.




  • The damage dealt is a percentage of the enemy's max HP. The higher their max HP, the more damage it will deal, making it extremely effective against certain bosses, such as Darkeater Midir.
  • Acts similar to Lifedrain Patch from Dark Souls II.
  • It deals damage to everything in its radius, including the caster. Try not to stand in it after casting. However, it does not hurt friendly phantoms.
  • This spell doesn't deal poise damage and will not stagger an opponent.
  • Very useful in killing mob enemies such as the Deacons of the Deep or the large crowd of Jailers in the lower level of Irithyll Dungeon, when used in combination with a lure such as an Alluring Skull or Aural Decoy.
  • This spell will not aggro most enemies, but they turn around and face the cloud except mimics(combined with Hidden Body+Slumbering Dragoncrest Ring works extremely good)
  • Its damage was increased by 150% in the 1.08 Patch. This makes it a very deadly spell, especially due to the spell having a long lasting and large hitbox, which pretty much guarantees death for opponents stuck in tight spaces.
  • The overall damage and duration is fixed; damage boosting skills, items, rings (Crown of Dusk, Young Dragon Ring/Bellowing Dragon Ring, Clutch rings, Steady Chant, etc.) do NOT work. The damage also does NOT scale with your stats. (Easily verified against any mimic). 
  • Only one Pestilent Mist can be one screen at any time. If the player or an invading or friendly phantom casts a Pestilent Mist of their own, the previous one will disappear. (This may not be true, needs testing.)
  • Note that while its picture does have the same corroded scroll appearance shared by dark spells, it still gains no scaling whatsoever even when cast with the Izalith Staff. It may be a dark spell in flavor, but it isn't in practice.
  • A host is immune to Pestilent Mist when a friendly phantom casts it (tested against Dragonslayer Armour). This allows the host to pull in enemies (more effective while wearing the Skull Ring).
  • Using this sorcery on the Dragonslayer Armour will prevent his phase 2, and grant a unique death.


  • Formerly called Pestilent Mercury, the Sorcery was renamed Pestilent Mist in Patch 1.15.

      Not like dark fog in ds2. This just creates a mist on the ground where you were standing they have to walk through. Not worth aiming for 30 int early game for this

        This spell is god tier against Old Demon King. I thought I'd use a sorcerer setup for my first time fighting him, using Izalith Staff in one hand and Pyromancy Flame in the other with Black Serpent, Farron Slashsword, Soul Greatsword, Deep Soul, Pestilent Mist, and Hidden Body (because I could) and switched between the spells depending on my distance from him and what he was doing, and the only damage I took was from my own Pestilent Mist lol.

            A surprisingly effective spell that's ideal for killing many enemies that are initially dormant, like mimics.

              HEY! Do you wanna kill the dancer and Oceiros at level 40 or so? Get this spell perhaps a sages ring and if you've got it the witchtree branch staff and cast it in front of them and watch their health melt. I advise getting behind a Pillar for dancer and doing the well-known cheese for Oceiros and then you will be set quite early!

                This spell is so good as a finisher for PVP. Since the meta is virtually melee, there are people antsy enough that they walk through this spell just for the chance to get a hit at you. You cast this at running distance in front of them and they feel the clutch, which lures them in. If their HP is less than 200, even with tears of denial, they will always die. A good spell to use along with Snap Freeze.

                  so nothing has been changed mechanic-wise? If that's the case, can someone please put the old name and description in the trivia?

                    this spell has definitely been nerfed and no longer deals percentual damage! At least not against Midir.. To me it does around 3/4 of my max HP and for Midir it does only like 1/6
