The Waterworks Delve Guide: Location, Boss Strategies, and Trash
This page will cover everything you need to know about the Waterworks Delve in the War Within Expansion, including strategies for events, trash, and bosses.
Getting into The Waterworks
The Waterworks is a Delve located on the West side of Ringing Deeps, Khaz Algar.

This guide will provide the all the specifics you need to complete The Waterworks across all tiers of difficulties (from Tier 1 to Tier 11). We will cover delve events, optional bosses (rares), as well as end of the dungeon boss and their abilities. If you would like to learn about the rest of the Delves in Season 1, please see our overviews linked below.

Events in The Dread Pit
The main goal of this delve is to make sure to use your Stomping Shoes around
Air Purifier so you can fuel up your Air Totem; otherwise,
a permanent stackable debuff will appear, significantly lowering your chance
of completing the Delve.

Event #1 — 0/50 Lost Gear found
Use Stomping Shoes near Kobold Corpses to gather 0/50 Lost Gear.
Trash Mobs in this Area
- Interrupt Kobold Mystic's
Fireball.
- Beware of Kobold Skullface and its
Scratch frontal
Bleed ability (you can out-range it). In addition, they will also cast
Kick, which is an uninterruptible knockback effect.
- Beware of the number of Cavernous Shriekers you pull as they do
trigger
Death Screech upon death.
- Interrupting Kobold Taskfinder's
Battle Cry is a priority in this area. In addition, avoid its
Blazing Wick frontal cast and be prepared for the heavy tank hitter
Thwack!.
- Interrupt Spitfire Charger's
Wicklighter Volley cast, while dodging the incoming
Fire Charge ability.
Waxface Boss Guide
