Felonious Twist was a mage that saw things differently. As an enchanter, he combined many things that weren’t meant to be together. A buggy that buttered toast, a bookcase without shelves, a harp with wine cooler, many things he made were just weird.
His finest and most useful item was the Skyswimmer cloak. By moving through the sky as a fish moves through water, Felonious Twist traveled the world, discovering new ways of doing many things and creating many strange and wonderful things.
Felonious Twist met his untimely demise trying to create a wagon that could defend itself like a porqupine.
The Skyswimmer cloak allows the wearer to move through the air as if they were swimming. They are boyant, although they can breath as normal. They do experience resistance to thier movement as if they were in water, so reaction times will be slower and awkward.
There is no limit to how long the wearer may swim in the air. They can go for as long as there is air to swim in and their endurance holds out. Winds will affect them as currents would, and any checks for actions use the swimming skill.
