I'm having a campaign coming up soon, and I have an idea for an NPC but I need help with one of his weapons. He's gonna be a cthuloid (custom race) and he's going to have predator style blade gauntlets. I want him to be able to hold a weapon while wearing them though, I have a basic idea though. They could work as a special type of weapon where when worn but unarmed you can hold and use another weapon in combat, but the deploy the blades takes a move action, while the blades are deployed you can hold a weapon but not use it on combat, and if nothing is being held you can use them for d6 damage (medium)[though, I was thinking of making him a large race]. The reason I want the weapon to work this way was because I wanted him to use a trident, but have the wrist blades as a backup if he was disarmed.
