A shocking burst weapon functions as a shock weapon that also explodes with lightning upon striking a successful critical hit. The lightning does not harm the wielder. In addition, the weapon explodes with electricity energy on successful critical hit, dealing extra electricity damage as set out in the table below. (This effect activates even if the target is not normally subject to extra damage from critical hits.) This burst does not harm you or any creature other than the target. This is a continuous effect and requires no activation. Even if the weapon has not been activated to deal extra damage because of the shock property, the weapon still deals its extra electricity damage on a successful critical hit.
