+1 for adding another Kaelensia, although not sure if I'd like to see them as a bat, maybe something of the mouse variety would be nice.

Not sure how merfolk would work though, as a Corrupted, that'd be interesting to see. Give them some boosts to water attack/resistance and maybe weaken them to ice or earth attacks. It'd be a weird one to RP as though, how do they survive on land? Can they move to and from the land without any issues? Is it similar to a transformation state? If so, what happens if it rains? (If I recall correctly one theory around mermaids was when on land if it rained their true form would be revealed)
