POPULATION / ZONE PROGRESSION
The Dreadcutter: The Pirate Kings [Raid]

• The scout cursed by the ogre witchdoctor should not be teleported unless there are not enough valid teleport targets.
• The pirate adds should no longer occasionally stop spawning.

Eidolon Jungle

• Shriekgloms in Eidolon Jungle will no longer alert other Harrowing Horde to your presence at such great distances.

ITEMS

• Shiverback King Loop no longer has the same effect as the Shiverback King Stud. It now has an effect that is more appropriate.

• Ethereal end line rings have been given their own effect and have been slightly improved.
