When the cumulative HP loss of the wearer during a single attack exceeds 25% of their Max HP, or if the amount of their own HP they consume at one time is greater than 25% of their Max HP, immediately heals the wearer for 15% of their Max HP, and at the same time, increases the DMG they deal by 25% for 2 turn(s). This effect can only be triggered once every 3 turn(s).
