The Sons of Salem

Tiny electronic robots emerge from the ring and burrow under the users skin. They crawl along under the dermis creating quickly moving bulges that travel into the users fingers, down their hand, past their wrist, and into the forearm before ballooning outward and spreading all over the body. The feels like their nerves are on fire as the tiny insects crawl along the internals of the body before finally arriving at the nerve receptors for the eyes and nose respectively. Once at the eye the user would see their tiny legs begin to snake into the their vision from the periphery. The nanite needs the eye to be looking forward so as the cornea moves to the side to see the legs they retract while legs on the opposite side continue to snake forward. Once the eye is stationary enough the bug legs lock it into place and another nanite crawls from the back of the eye and enlarges over the cornea. Once in place it's tiny legs inject past the cornea and into the optic nerve behind it. Afterwards the user sees a thin HUD outline of what the other nanites have already found relayed back to the user. As for the nose once the nanites are in place at the nerve ending the user would have a sudden drop where they couldn't smell anything for a few seconds followed by the smell of metal and burning plastic for a bit, then the new senses would be online. The nasal cavities become filled with tiny nanites buzzing and humming from inside.

Tiny nanomachines begin to pour out of the ring and skitter around the user in an outwardly growing sphere. They burrow into floors, walls, roofs and doors and continue to move unnoticed with the user for the duration of the ability before dissolving. While active the bots scout slightly ahead and ping back information to the ring that they emerged from, mainly focusing on electronic items but also recording interesting smells and cataloguing them for investigation.

The object seems gleam as if it was made of bronze. It's edges are honed to such a fine point they almost sing. This is not just excellent craftsmanship, every atom has been fully dedicated to it's purpose.

A language processing module, arcing with purple electricity as it enables a person to understand any language spoken to them by anything the device deems..intelligent enough.
It actively encourages you to kill anything that it cannot understand.
Upon the device running out of charge it will wish you a goodnight in a random language and then disable itself until it has fully recharged.

A little electronic ball, when taken out and placed on an object, the ball uses the body energy to create a infinite cycle of feed for the nanites. Which will spread out from the ball and repair the object. On the flipside though, if it detects the object is in full working function, just missing fuel, it will absorb gravitational energy waves and latent signals, such as radio signals, xrays, UV rays, etc and turn it into a source of fuel for the machine. Though due to such exposure and change, the nanites within the machine will die out in 24 hours, requiring a re-establishment.

When stabbing with the knife, it seems as though it can cut into things a touch easier than most. When hitting demons though, it burns them with a fiery fury within their now desecrated soul.

This device is a piece of chrome the size and shape of the back of a spoon. When placed against the skin, small hypodermic needles sprout from the device and attach it to the user's bloodstream. There, it filters and releases lifesaving drugs into the bloodstream, granting complete immunity from contracting new diseases and added resiliency in all other cases.

WARNING: The immunizing drugs have been shown to reduce inhibitions in test subjects.

The mad scientist can craft steel helmets that protect their wearers from mental influence and attack.
