|Status||Deceased (lore), Killable (WoW)|
Mutanus is the final boss in Wailing Caverns. You must return to the entrance to summon him. He'll appear during the Naralex event after 2 waves of smaller mobs. He hits quite hard, and if he catches you off-guard, he could potentially wipe out your group. Make sure you eat and drink before he spawns. Mutanus has a powerful sleep spell called Delusions of Naralex which he will sometimes cast during the fight. Only enter at full health.
Mutanus appears to disrupt any attempt by the Disciple of Naralex to wake the sleeping Naralex. Manifested from Naralex's Nightmare, Mutanus the Devourer has been ordered by whatever force has infected Naralex's dreams to prevent anyone from awakening him. Mutanus appears as a colossal albino murloc.
From the darkest corners of Naralex's twisted mind, the corruption plaguing the Emerald Dream has manifested in the form of the druid's worst enemy: murlocs. The aberration known as Mutanus has come to the waking world to devour any who seek to liberate Naralex from the Nightmare's clutches.
