Vulnerability is a spell in the standard spellbook. When successfully cast on a target, it will increase the damage they take from all sources by 10%. This means a target that would take normally take 2,500 damage will take 2,750 damage (250 being 10% of 2,500). It is often used against high-levelled bosses such as Telos.

This spell can be used simultaneously with Curse (the weaker version of Vulnerability), but Vulnerability's effects will have a higher priority.

  • Before the Evolution of Combat, Enfeeble and Stagger were used alongside Vulnerability for training Magic in metal armour because the spell would always miss with a low enough Magic attack bonus (-65). It could be re-cast indefinitely in this manner, resulting in quick experience. However, this spell no longer gives any experience for missing.
