[@13org] I’m not super picky about how magical they can be.
Obviously nothing OP. They definitely can be used for fighting but in short durations, typically for one post and then would need to recharge. 

Example:

First post: power activated then wears off by end of post 

GM post will detail damage/effects of enchantment use 

Second post: Ability recharges

Third post: Power recharged and ready for reuse. 

Rinse, repeat. If it’s a heavy or powerful attack, then it takes longer to recharge. Still haven’t finalized the system but that’s the gist of how I’d play them.
