Vulnerability is a spell in the standard spellbook that increases the target's damage received by 10% for 1 minute.

Before the Evolution of Combat, Enfeeble and Stun was used along side with Vulnerability for training Magic in metal armour because the spell will 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 experience for missing, and is therefore not recommended for training Magic.

Remember, you cannot use Ancient Magicks or Lunar Spells if you are using standard spells.
