Magic Weapon Abilities - Doom Burst
A cascade of blackness pours from this weapon when its wielder strikes true. On a successful critical hit, the weapon causes the victim to become shaken (no saving throw) for 5 minutes. This effect activates even if the creature struck is not subject to critical hits (roll to see if a critical hit occurs, then apply the shaken effect if appropriate). A creature that is already shaken is not affected aside from the critical hit damage.
