I want to try some power sets I've never used and am looking for suggestions of a good secondary for staff that is NOT one of the following:
Bio
Fire
Ice
Radiation
Regen
Shield
Super Reflex
Willpower
So unless I'm forgetting something what is left is:
Dark
Electric
Energy
Invulnerability
Ninjitsu
Of those, is there one people would suggest to pair with Staff?
