Resonant Echo

Resonant Echo is a homebrew spell created by Matthew Mercer for Campaign Two: The Mighty Nein. An ability similar (although not identical) to the spell was thereafter incorporated into the Explorer's Guide to Wildemount as an ability for the new class of Echo Knight, rather than as a spell.

Spell description
As an action, the caster can make a shadowy clone of themselves. They can use the clone to cast one spell. The clone then vanishes after using that spell. It has a limited number of hit points, but greater than thirteen.
