Each of these black steel bracers is marked with an etching of crossed swords.

When activated, deathstrike bracers allow you to use melee weapons to deal extra damage from critical hits and sneak attacks to constructs, elementals, oozes, plants, and undead as if they were not immune to such extra damage. You must still roll a critical threat and confirm it as a critical hit or qualify to deliver sneak attack damage to gain any benefit from the bracers. This effect does not allow you to overcome any other immunity or resistance to extra damage from sneak attacks or critical hits (such as the fortification armor property).
This effect lasts for 1 round.
This ability functions three times per day.

Prerequisites: Craft Wondrous Item, keen edge.
