I'm trying to create powers that are based around an object like a spear, ring, gloves, cape, etc.... I've send a disadvantage on another website that was called unique focus, but I was wondering if there was something official here. Now, psychic artifact nor goldber really give me what I want which would be something similar to Green Lanterns ring and other objects--some of which are in the setting. So how would you build such items? Do they break the system?
