Iron Will is an ability learned from the Toughness skill.
It provides Damage Resistance (a percent reduction of all incoming damage) and a temporary Health that can extend beyond your maximum Health. When this expires, the bonus Health is lost (to a minimum of 1 Health - you cannot die from losing the bonus Health).
