Vulnerability

Vulnerability is a combat spell. When successfully cast on an enemy, their Defence level is reduced by 10%. The effect cannot be stacked, meaning casting the spell on the same opponent multiple times has no further effect.

A Magic level of 66 is required for this spell, giving 76 experience regardless of whether it hits or not. It requires 1 Soul rune, 5 Earth runes, and 5 Water runes to cast.
