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
Are you trying to avoid killing all NPCs as opposed to just innocent NPCs? That'll make this rather difficult. How do you feel about "killing" undead creatures or deadra?
I can't think of too many quests, honestly.
Bleakrock Isle: some of the pre-evacuation quests, like rescuing people and the fighters guild folks.
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
Arx Corinium
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.
