Riftwolves

Riftwolves, also known as Wolves of the Rift or Rifthounds, are an elite enemy group hailing from the Abyss. They are mainly found in Tsurumi Island, Inazuma but can also be found in The Chasm, Enkanomiya, Sumeru, Fontaine, Natlan, and Wolvendom (after completing Lupus Minor Chapter: Act I). In combat, Riftwolves use elemental attacks, and any attacks that make contact (including those absorbed by shields) will apply a party-wide corrosion debuff, which continuously drains HP from all party members while active. Riftwolves also utilize a fury system, which accumulates when they are hit by Elemental DMG of their own type. When this bar fills, the Riftwolf enters an Elemental Devour state, which increases the ferocity of its attacks, but also decreases the Elemental RES of their own type.
