A thing that my sona, Foxfencer, does for an income is invent various potions to sell on the market. The potions are guaranteed to be temporary and you'll be back to normal in a couple hours or so, maybe longer; just enjoy the experience.

However, Fen has problems with recruiting willing test subjects on a regular basis, so for his most recent creation, he's had to test the potion out for himself to test the strength of it.
To his reluctance, it took him a whole 24 hours before he came back to record his data and findings.
Clearly, the version of that potion that he mass produced was heavily diluted from it origins.

Art by me (was just an idea I wanted to draw; probably not gonna improve on this sketch any further)
