Tweaked from 5eYou already know this as 5e Thunderwave — It's basically your Thunderwave — a sound-based burst that erupts from you forcing a Con save in a ~15-foot area — but it hits harder, adds psychic damage, and deafens instead of shoving creatures back.
Burst a 15-foot radius for 4d6 psychic + 4d6 sonic damage, deafening every failure until the end of its next turn.

You emit a scream imbued with the power of the Force. Each creature you choose within 15 feet of you must succeed on a Constitution saving throw. On a failed save, a creature take 4d6 psychic damage, 4d6 sonic damage, and is deafened until the end of its next turn. On a successful save, it takes half as much damage and isn't deafened.
