Umbral Burst

*Price +2 bonus plus 6,000 gp; Aura strong evocation; CL 12th; Weight —
An umbral burst weapon functions as an umbral weapon that also explodes with shadow energy upon striking a successful critical hit. The shadow does not harm the wielder. In addition to the extra shadow damage from the umbral ability, an umbral burst weapon deals an extra 1d10 point of shadow damage on a successful critical hit. If the weapon's critical multiplier is x3, add an extra 2d10 points of shadow damage instead, and if the multiplier is x4, add an extra 3d10 points.
Even if the umbral ability is not active, the weapon still deals its shadow damage on a successful critical hit.
