im currently making a skill tree for a Rogue of Rage, any ideas on what should be on it? powers and the likes

If you’re doing a Skill Tree in the sense of choosing to go down one branch or another, you should consider a divide between Pacifying and Enraging. After all, by Taking Rage one can calm others down, but you can also stockpile Rage for yourself. A Rogue of Rage may also work as having a branch to be a Tank? If they Steal everyone’s Rage, you could say they’re directing everyone’s hatred towards them- So either literally Aggroing others, or acting like a Heel could be a thing.
