Thanks for playing! Currently no difference, but the plan is for them to grant the player additional attacks that trigger automatically. The passive effects will come mostly from the crests you slot in to them, not just stats like it is now. Just did not have nearly enough time to implement this haha. The problem of hovering in the center is an interesting one I haven't though about much yet, I will need to have a good design think about that one, thanks a lot for pointing it out!
