Group sword

Damage 1d6 piercing

From blade to pommel, this sword is carved from a branch of the now-extinct celestial peach tree. The blade of this +3 greater striking holy vitalizing peachwood shortsword has ancient runes that can permanently destroy the most powerful undead—if you are willing to pay the price.

An undead creature of 12th level or lower that takes damage from a Strike with the sword takes 10d6 vitality damage with a DC 35 basic Fortitude save. This damage is separate from the Strike itself and isn't included in any effect based on the Strike's damage.

Activate—Violent Exorcism (concentrate)

Frequency once per day

Trigger You critically hit an undead creature with the sword

Effect The creature must succeed at a DC 35 Fortitude save or be destroyed. If the undead fails its saving throw and is destroyed, you suffer a backlash, taking 1d6 void damage per level of the destroyed undead.
