Époisses Breath

You can temporary disable enemies with the power of Époisses, a cheese well-known for its stench.  As a bonus action, choose one creature within 5 ft. of you.  That creature flinches and cannot take reactions until the beginning of your next turn.  Creatures that lack a sense of smell (GM's discretion) are unaffected by this spell.

This spell is intended to go with the School of Cheese wizard subclass.
