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.

An object brandishing these neuron-like engravings infuses the wearer with a magical energy that let's them stay mentally active for 24 hours a day. The user can also decide to put themselves into a sleep-like full body stasis, making them independent from any need for resources, while keeping their mind awake.
If you want to study faster, 30% more waking hours are a very efficient way to do it.

When activated, the badge will glow lightly and the shield will not appear unless attacked, which then the shield will appear as if the attack hit a glass window, and either bounce off or shatter the window.

a user, perhaps inspired by the lore of the leprechaun, holds a shillelagh, a traditional Irish wooden walking stick. With a sense of wonder and anticipation, they mimic the actions of the mythical leprechaun and tap the shillelagh on the ground. The moment the stick contacts the surface, something extraordinary happens.

The ground beneath their feet begins to shimmer and swirl, opening up to reveal a glowing portal. It’s as if the tap of the shillelagh has unlocked a hidden, mystical doorway. The user, filled with a mix of excitement and a hint of apprehension, finds themselves suddenly dropping through this portal.

As they fall, the world around them transforms. Colors and lights blend in a kaleidoscope of hues, creating an ethereal tunnel around them. The sensation is otherworldly, as if they’re traveling through a conduit of magic and ancient energy.

Suddenly, the journey comes to an end as they emerge from a hole in the ground in a completely different environment.

Eight runes are scratched into the metal surface of these containers on the outside corners, and eight on the inside. When activated, a faint werelight outlines them as the container shrinks and morphs into a metal cigarette case with a runic design in the center. Activating this expands the container back to its full size. From inside, the runes glow faintly for as long as the container is shrunk(this does not provide illumination, but indication)

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

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.
