Can my paladin use the abilities of the previous classes? I accidentally clicked on the barbarian ability retribution and it stated there.

You can use every abolity from other chars

You csn and you should. Pala skills sux hard

guessing not from the ones not unlocked yet as they are in a different shade of red. I'll be definitely be using other skills next climb with him that revenge skill sucks hard for solo.

Thanks

you can use any skills, the only thing that changes is the rate at which they charge

blue charges the quickest, pink slower cuz off class but a class you've unlocked already, and dark red the slowest cuz off class and a class you haven't unlocked yet

retribution, powerstrike and revenge are what i use for solo pally
