Basically on who prefers what kind of combat
Rk: jack of all trades melee with blades long and close rage with firearms even if his are antiquated by about 3 billion years and magic more so in the destructive and alteration type over all he prefers the blade to cut down waves of foes with flashing steel and crimson torrents.
Nindel: hand to hand blades and long and close range firearms alteration and concealment magics more the stealthy and hunter type prefers to lay traps but enjoys stalking a target and will use her tail often in close range in either a constricting or piercing manor she gets more satisfaction with impalement .
Tech: heavy artillery pin point orbital strikes she has a direct systems link with the Null and can order bombardments and pin point laser strikes to the point of orbital assassination strikes she’s a one and done kind of cybernetic gal.
I’ll keep adding to this as I go.
