Hm what about a upgrade for the organic form where they can latch on a Borg and after x amount of time the yin enslaves it or becomes it in an yin hacked form or something.
it would be pretty cool if diona can heal other diona
Option 1 : have a amount of nymphs per diona and it can shed one for another diona to heal or increase maximum health except for burns
Option 2 : place hands on another diona and channel life energy hurting the giver but healing brute damage for reciever
