Here's an idea thread for general gadgets and gear ideas to throw around. I'll start with a few.
Reactive Camouflage Veil / Shroud
Battery powered shroud that provides a large boost to stealth when turned on by replicating the shroud's surroundings. When turned off, operates as a normal, albeit much fancier shroud. Looks clean and high-tech instead of being a ratty wizard robe like normal ponchos.
Snake Camera
Able to fit under doors to observe another room, can be spotted and wrested out of the operators hands, but is difficult to spot without searching. Requires batteries.
