You said existing characters are fine so here's this nerd. #NovaWGE
I forgot to list skills!
I'll just use his original but less powerful since lower. Also I'll only give him a few of them!

-Reviving (Pros: Comes in handy, revives.
Cons: Doesn't always work, makes him really weak for awhile(even if it doesn't work))
-Can teleport short distances
(Pros: Can quickly escape, useful on quests.
Cons: The location is random, but it'll always be somewhere familiar)
-Crystal shards (Defense)
