The Underrot in the Adventure Guide

Dungeon - Battle for Azeroth

The Underrot

4 encounters, 26 boss abilities and 39 drops, with the Adventure Guide’s own ability and strategy notes for each fight. Every drop links to its item page; tradeable drops carry a live Auction House price.

Deep within the swamps of Nazmir, a blight grows beneath the surface. Unless this corruption is purged immediately, its influence will spread across the land like a ravenous plague, leaving behind nothing but a festering world.
