I have 2 specific characters I have made that are seekers of truth. They cant kill or steal etc...they are essentially seeking purity. Are there any quests where the tasks are not killing or stealing & in that kind of roleplay. Thanks
You could become a werewolf, but not a vampire, since I think the werewolf quest only requires killing a beast.
As for group dungeons, that really depend on whether you are okay with killing goblins, lamia, undead or Daedra. If those are okay, you could run:
Fungal Grotto 1
Banished Cells 1
City of Ash 2
Wayrest Sewers 2?
Crypt of Hearts 1
Cyrpt of Hearts 2
Blackheart Haven (technically those guys outside are under the undead curse too)
Vaults of Madness (quest requires you to kill an NPC who requests it)
I dont have the latest DLC dungeons to judge, and I may be mistaken about the dungeons above. I dont think they have human/mer enemies, but its entirely possible I forgot someone.
And then stick to easy normal dungeons, because on any harder content healers are expected to do more than just heal and buff. I mean, you can just heal and buff, but the vast majority of healers also do damage because that's part of effectively supporting the group.
