Followup The Troubled Keeper

Walkthrough
You have to survive 4 waves of torments. The third and fourth bring along a boss each. It can be done with henchmen, but may consume a bit time. Always bring down the spellcasters first!

This quest is easily completed with 3+ humans equipped with Lightbringer's Gaze. You can simply stand at the resurrection shrine with 60dp and kill the enemies with the lightbringer gaze one by one.

Completing the quest with henchmen may be more difficult.

Bring a monk, 2 tanks, and an SS with Backfire. Have the monks cast Protective Spirit and Shielding Hands on you, use Death Nova on the party, and have the SS cast Backfire on a healer. Use Putrid Explosion for spike damage or Necrotic Traversal for more degen. If you have a chance, animate a Flesh Golem, and put Death Nova on it.
 * For those "desperate necromancers" who want the elite skill:

If you are doing this with heroes/henchmen, I found that it helps to bring everyone away from the Resurrection Shrine after you have died and resurrected. You can flag a spot behind where the mobs are. The heroes and henchmen will run to that spot after they are resurrected, which will make it easier for you to hit the mobs.

This quest is actually easily done with heroes/henchmen. At the start run northwest a short way so as not to aggro the mobs that are approaching. Now just pick off the last mob (group of 3). Often, atttacking the Quickening Zephyr spirit will aggro just the mob you want. When these die, go back to your safe spot. The next group of mobs will spawn and run towards the res shrine; again, just pick the last mob of the group off. Repeat this till the boss spawns and kill him. The quest will complete even though most of the enemies are still alive at the res shrine.
