Elden Ring Poisonous Mist Guide, Notes & Tips

• This is an Ash of War Skill, associated with the Ash of War: Poisonous Mist.
• FP Cost: 14 on use.
• Deals 12 stance damage
• This Skill is not Chargeable
• On input, coats the armament in poison while swinging out a green mist that slightly travels forward, and lingers for a short period of time.
  • Both parts of the skill (swing + mist) apply poison buildup on enemies. Both apply the same poison buildup.
  • The swing also deals damage if it connects.
• The mist applies 120 base poison buildup per tick, and lasts for 5 seconds.
  • The poison buildup of the mist changes depending on the weapon's affinity, as it scales with the Arcane stat.
• The poison coat adds poison buildup on hit to the armament (counts as a weapon buff), which lasts 40 seconds. (Since Patch 1.07)
  • The poison buildup from the buff adds 60 base poison buildup, but changes depending on the weapon's affinity. as it scales with the Arcane stat.
    • Poison affinity has good Arcane scaling (tied with Blood affinity), beaten only by the Occult affinity. At Arcane levels close to 80, an Occult weapon with Poison Mist active can deal even more poison buildup per hit, than that same weapon with a Poison affinity and Poison Mist active.
    • An affinity that has no Arcane scaling at all will have considerably lower poison buildup per hit when Poison Mist is active. This remains true even if the player has a very low arcane stat to benefit from the Poison/Bleed/Occult affinities.
• Note: This Skill was changed with Patch 1.07 as follows:
  • Motion speed has been increased.
  • Duration of the weapon's poison effect has been increased.
