Vulnerability is a spell in the standard spellbook that temporarily reduces the target's Defence level by 10%. It does not stack with Curse, any Defence-draining Ancient Curses such as Leech Defence, or itself; once the target's Defence has been drained by any effect, it cannot be drained again.
Along with Enfeeble and Stun, Vulnerability is sometimes used for training Magic in metal armour and with a mud battlestaff or mystic mud staff. Because the spell will always miss with a low enough Magic attack bonus (-65), it can be re-cast indefinitely in this manner, resulting in quick experience.
