Based on a couple of suggested words (sleepy and cornucopia) from my Discord server, I came up with this spell. It creates a magical feasts, but actually eating it could be a bad thing.
It's meant to draw on the ideas of a cornucopia of endless food, and the sleepiness (and difficulty moving quickly) that a large meal (such as tomorrow's Turkey Day) can cause.
I'm thinking it would have originated with a tricky fey spellcaster before it was stolen by a rival.
