Despite the fact they were OP in origins my warden (Elven mage) generally just abused people to get the results he wanted but was such a good guy lol. I only ever used 1 save with him and only used that If it was a extremly hard battle (Flemeth, Final battle, High Dragon)
Saved the kid and got blood magic. Scared the demon away to do it. :D
Sided with mages, since... magic is kind of what I use.
Cured the werewolfs
For the dwarves I did the same as Endmaster
Kept the ashes safe due to me romancing Leliana.
Killed loghain since I was planning to die at the end anyways. Made Alistar King and locked Anora away.
Rejected morrigan, (We were friendly but I didn't exactly trust her to take care of an old god possesed child.)
For Awakining I more or less roleplayed as a cousin to my original warden. He was also a mage.
-Rebuilt the wall and saved amaranthine.
-Same as Endmaster
Didn't do "Witch Hunt" since she didn't get the child and I had no reason to follow her.
