Hand Mirror of Hideousness
This hand mirror is much prized by vain nobility. It reflects upon its holder a most hideous visage, a terrible corruption of their own face. If the holder stares at it for 1d3 minutes without blinking, it transmutes their face into a prettier version. This has no effect on the holders personality. Should they blink before 1d3 minutes passes however, their face transmutes to be as bad as the vision they saw while looking at it, and oftentimes worse.
On the back of the mirror is a badly written poem that serves as the instructions:
Face your inner self unblinking for minutes thrice,
Your visage will soon be nice,
Fail to head this missive and be punished by your vice
