Each of these jet black bracers is set with an oval of tiny, ruby-red stones.

Bracers of the entangling blast allow you to reduce the damage dealt by your magic to ensnare those affected by it. When you activate these bracers, the next spell you cast or spell-like ability you use deals only half its normal damage; however, any creature damaged by the spell becomes entangled for 1d3 rounds, taking an additional 1 point of damage per level of the spell each round on your turn. This damage is of the same type as normally dealt by the spell (or your choice if the spell deals more than one type of damage). These bracers have no effect on a spell or spell-like ability that doesn’t deal damage.
This ability function three times per day.
