POTIONS OF GNOMIFICATION
Description: It's a small world.
Duration: Until shrine or zone.

Description: Your tiny life acquires a pointy hat.
Duration: Buggy. You can't TR out. You are a gnome forever.
The potions that also give your character a tall red pointy cap cosmetic should (of course) cost more and perhaps have other drawbacks in the name of balance.
