Will they regenerate back over time if destroyed? Also how do they effect your character's ability to wear clothing? Is he forced to have them slip through his sleeves all the time, or will he be walking around shirtless? Which would evidently cause him to feel more exposed and defenseless despite his ability to defend himself with his invisible weapons.
