Fleshreaver Hounds are Smiting monks with powerful AoE spells and tend to form the bulk of the fleshreaver forces. They resemble Griffons in appearance, only more decayed.
Beware when using AoE hexes and conditions on these enemies, since this allows them to use their Smite Hex and Smite Condition at the same time on each other, causing a powerful nuke.
Although they appear undead, fleshreavers are considered Fleshy and do not receive double damage from Holy Damage.
