- Necromancer Tamsyn
- Necromancer Rask
- Necromancer Gwick
- Some of the undead ask you to release their souls from soul jar. These soul jars can be found inside illusionist's cave.
- After going through the Gargoyle's Maze, there is a tower with many undead inside. Talk to Necromancers then kill them. Loot Filthy Iron Key. The Necromancers will respawn later, so you may want to leave them once you loot the key. Destroy their soul jars in Dark Cavern associated with the quest The Vault of Braccus Rex.
- Killing the trio of Undead Necromancers at least once before using their soul jars will reward you with added experience
- You cannot use the soul jars while in combat with the Necromancers
- If you gave one of the Soul Jars to Gratiana you will not be able to complete this quest (fixed in recent patch).
