Great pun, but Hairy is a meta-template that.can be applied to almost any statblock. Boosts the CR of a creature by 4 and grants it advantage on saves against most forms of debilitation or quick removal.

My favorite application for room-temp superconductors is low-speed generators. They have exactly one application, but it’s big: Wind towers without a giant gearbox. Wind power is cheap, but without the truck-sized gearbox with a bazillion moving parts that you can’t lift without the biggest cranes known to man, it’s even cheaper.
