Vorpal Item 17

Pathfinder Core Rulebook (Second Edition), page 585

Category Runes; Price 15,000 gp; Usage etched onto a slashing melee weapon

Originally created as a means of slaying the legendary jabberwock, vorpal weapons prove equally effective against nearly any foe with a head.

Activate ↩ envision (death, incapacitation); Trigger You roll a natural 20 on a Strike with the weapon, critically succeed, and deal slashing damage. The target must have a head;

Effect The target must succeed at a DC 37 Fortitude save or be decapitated. This kills any creature except ones that don’t require a head to live. For creatures with multiple heads, this usually kills the creature only if you sever its last head.
