This device is a foot-long skeletal hypodermic needle filled with foul-smelling, green ectoplasm. The user must have the Reinforcer connected to an AI/O port when injecting the needle.
The user inserts the needle and injects the ectoplasm into any intelligent subject and makes Powers check with the subject's Magic as it's Difficulty. The target then expends an Magic point and grows a temporally, hard, insect-like shell which provides 3 points of armor protection with no hindrance. The armor lasts for a scene.
Using this on an unwilling target requires a Setback with Stunts.
