Per Patch 1.60:
- Malignant Creatures: All players should now be able to complete this quest.

- Animists and Valewalkers should now be able to continue working on the Stoneheart Quest.
The Malignant Creatures quest starts in Little Haven in Caldey. Little Haven is around loc 46/19. The NPC that gives the quest is Mordwywr (the enchanter in town). Mordwywr is in the largest building in Little Haven. I received this quest at L48 and the reward includes a L48 gem - not sure if you can get the quest before that level.
You have to kill 7 undead creatures. I killed these: phantom magi, defiled skeleton, headless footman, grasping ghoul, ebon skeleton, corpse delver, and haunted rowan -- all yellow and easy kills to a level 48(found at loc=60k 56k).
Quest reward was 6 gold and some copper, 2,377,658,624xp (about 3/4 bub I think to L48), and a gem for jewel slot, most likely class specific. I am a wizzie and received Caster's Minding Thoughts.
I did this at 46, all mobs were yellow to me as well. I only received 1.8 billion exp, but it was still 3/4 of a bub for me -- I think therefore that it scales according to level.
My reward (as a friar) was Darkening Powers.
A 48 scout received 2.3 billion exp.
I tried to kill other undead, but only the ones on the list dropped items for me. The three that didn't were corpse mold, gangrenous mass, and a ghoul desecrator. The gem I got had 5 charges of a 15s self damage shield, with a delved rating of 5. Since someone else got a different gem, you might actually get a decent charge on one. 1.8 billion xp at level 46, roughly a bulb or a little more.
A lvl 43 friar with us couldn't get the quest yet.
