Gloves of Power are supposed to impose Bane on the person the wearer attacks, but when I wear them, my character gets Bane when he attacks others.
If you don't have the mark of the absolute, the gloves turn on you. That confused me at first, too - there should be a more obvious callout for that. A message that pops up the first time you attack with them that says "something about these gloves feels wrong to you" or something.
