Humanoids take full damage.
Undead take double damage. This ring is only useful when you are allowing yourself to be hit, my character usually has a sheild spell on and cannot be hit, so the ring is useless. The rose wilts away when it's power is used to much and will eventually die. A skilled lockpicker may even be able to open some magically locked doors with it. The power can only be used once a day.
