In all my travels I've never seen something quite so freakish. It's as if a sloth and a slug had too much wine and awoke the next day with regrets.

Scholar Glenna

Slothasor serves as the first boss of the Salvation Pass raid wing. It is a giant sloth that was affected and mutated by the heavy concentration of magic released by the Elder Dragon Mordremoth's death or the White Mantle's experiments[1], turning into a sloth-slub hybrid.

Encounter related[edit]

Effects applied to players
Arena mechanics
  • Toxic Cloud - The ground around most of the arena is poisoned (green floor) by the small, purple mushrooms quickly stacking highly damaging poison on anyone standing in it. Poisoned ground can be temporarily cleared by a player who becomes a Slubling from eating an Imbued Mushroom. The poisoned ground will slowly respawn in previously cleared areas as the fight progresses.
  • Imbued Mushrooms and Slubling transformation - Players can interact with an imbued mushroom to consume it and transform into a Slubling for up to 45 seconds. Doing so aligns them with the enemy mobs and makes them appear hostile to fellow players. Transforming grants the ability to eat purple mushrooms, clearing an area of poisoned ground. After this effect expires, the player becomes Nauseated and cannot eat another imbued mushroom for 4 minutes.

    Scholar Glenna: Hard to say if the White Mantle experimented on him or the residual magic released by Mordremoth caused him to mutate.
  2. ^ a b "Jason said that Gorseval—which is now built on a wyvern rig—originally used the same bipedal minotaur rig that Slothasor uses. The same rig has been modified for use with several different creatures, including minotaurs, steam minotaurs, oakhearts, and what was described internally as a “buff sloth.” That buff sloth would eventually be known as Slothasor."
