d20 Future: CODEX GALACTICA
Power Cestus (PL7)
Consisting of a forearm-length metal gauntlet, the power cestus uses gravitonic capacitors to lightning the gauntlet for the wearer but without losing any of its terrific smashing power (or the wielder’s speed). When used the power cestus increases the base damage by an unarmed strike by + 2d4 points and turns the damage into lethal damage. The cost and weight given are for a single item. (Source: d20 Future Tech p.21). Like the original ancient Cestus the Power Cestus cannot be used while the wielder is wielding a weapon on the specific hand. The weapon needs no specific proficiency to be used and a user that uses the weapon counts as armed even if he has no feat related to unarmed combat.
