An icy burst weapon functions as a frost weapon that also explodes with frost upon striking a successful critical hit. The frost does not harm the wielder. In addition, the weapon explodes with cold energy on successful critical hit, dealing extra cold 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 frost property, the weapon still deals its extra cold damage on a successful critical hit.
