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.

 

 

Notes

  • 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, with the exception of mimics.
  • 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 are 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 per player can exist at any given time. Any number of other phantoms may cast Pestilent Mist without removing the others.
  • 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.

Trivia

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

      Pestilent Mercury was such a better name. Brought up alchemy comparisons, as well as making sense as Mercury is real toxic. I get the translation argument, but I do feel like the "mistranslation" actually turned out to be an improvement.

        The lowest this could damage is 10s then as the HP is higher I have seen 11 and 12 Recommended way to cast is using Sainttree Bellvine on the left hand and then two handing the staff. Bellvine is tucked in the pocket and the casting time is much better or at least good enough.

          just a FYI: casting this on an un-aggroed target using the slumbering dragoncrest ring prevents it from turning towards the cloud.

            The damage isn't always the same % of an enemies max HP. It kills some enemies in one cast, others in two, for example. Bosses take much more casts.

              Insanely effective against Deacons of the Deep, anything clustered, and anything, bosses included who are slow ore stationary.

                As of February 1st 2018, Pestilent Mist is limited to one per caster. I tested it on the Curse-Rotted Greatwood with 1 white phantom. I could not have multiple casts active at the same time but between myself and the spirit we maintained 2 active Pestilent Mists casts, 1 each. Furthermore, Pestilent Mist damaged every enemy that entered it but did not damage friendlies (friendly phantoms, host of embers, etc..). it would however damage the caster if the caster entered the mist. Also, Pestilent Mist damaged the Curse-Rotted Greatwood if ANY part of the boss touched the mist, not just its balls. During the 2 fights where I used Pestilent Mist against the Curse-Rotted Greatwood, the second phase did not trigger and drop us through the floor until the boss died.

                  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.
