Vulnerability is a level 66 Magic spell. When cast on an opponent, their Defence level is reduced by 10%. The spell gives 76 Magic experience per cast and requires 1 Soul, 5 Earth, and 5 Water runes to be cast. The spell can only be cast if their stats haven't already been lowered, meaning you cannot stack stat reduction with multiple spells in a row.
