A cestus is an ancient battle glove, sometimes used in pankration. They were worn as are today's boxing gloves, but were made with leather strips and sometimes filled with iron plates or fitted with blades or spikes, and used as weapons.
Makes me think of
Graviton Punch. There was another old
card that involved using a punch-like attack (something to do with finishing off the opponent, but I can't find it ATM.)
Weapon Composition :
(metallic in nature)
Attack Style :
(there seems to be a forum trend of having Gravity be the 'boxing elemental' =P),
/
(double attack),
(aggression)
Alternatives :
(The ability doesn't seem particularly fitted to one element style - see 'Attack Style') or
(If the weapon was changed it could be a weapon using accelerated time.)
I voted Other.
