This Ash of War grants an armament the Poison affinity and the following skill: Poisonous Mist: Bathe armament in poison, and then slash, spreading toxic mist forwards. The armament retains its poison for a while. Usable on melee armaments (whips, fists, and claws excepted).

Ash of War: Poisonous Mist Location in Poisonous Mist: Dropped by a Teardrop Scarab at the southwest section of the Aeonia Swamp in CaelidRegion. This teardrop scarab can teleport a short distance if the player gets too close. If available, apply appropriate measures to kill it from range. 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. Consumes 14 FP on use. Not chargeable. 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 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. The poison buildup from the buff 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.
