Disrupt undead

Disrupt undead was an arcane cantrip that hurt undead creatures or made them more susceptible to harm.

Effects
Prior to the Spellplague, this cantrip did a small amount of damage to an undead creature at a range of (farther for more experienced casters) by firing a ray of positive energy at it. If the target resisted the spell, it had no effect. After the Spellplague, this cantrip instead reduced the protection provided by the dark forces that animated and shielded the undead creature.

Components
This cantrip required only verbal and somatic components to cast.
