Could you give a little more details? As I understand it right now, they use the gloves and get the first penalty on their attack rolls and the bonus damage if they hit?

And they can use the gloves as a free action until they are satisfied with their roll? So, let's say I roll a 12 for my touch and with all modifiers I'm not happy, I get to reactivate the gloves and reroll ? If that's the case, it's really powerfull.
