Pop

A button pops off your clothing.

Piff

A pixie appears and immediately flies away

Ants!

Your hand or spellcasting focus is suddenly covered in ants.

A thick cloud of lunar moths appears around you

A 5-foot radius around you is obscured. You cannot see out of this cloud for 1d4 rounds.

You grow a duck bill

You can only quack for 1d4 rounds. You won’t be able to cast spells with verbal components during this time

One of your fingers becomes a harmless sparkler firework

A tiny swarm of gnats appears near your hand

You smell like Draggon Noir

Forked tongue

Your tongue splits in two. Every other sentence you say is a lie. Your companions must roll perception against a DC 15 to determine if you are lying.

Meep

You can think as normal, and while you think you speak complete sentences, the only sound that comes out of your mouth is “meep.” No one understands what the meeps mean. You also cannot write anything but “meep.” No matter how hard you try.
