Distressing Resonance

4th-level evocation

Casting Time: 1 action
Range: 30 feet
Components: V, S
Duration: Concentration, up to 1 minute

You create a field of subsonic vibrations in a 30-foot-radius sphere, centered on a point you choose within range, that causes physical distress and extreme discomfort. A creature in this area or that enters it after you cast the spell must succeed on a Constitution saving throw or be incapacitated until the beginning of its next turn. On a successful save, the creature can act normally. If a creature begins its turn in the area, it must make another successful save to avoid being incapacitated. Constructs, deafened creatures, oozes, plants, and undead are not affected by this spell.

The vibrations from the distressing resonance interfere with tremorsense, negating any use of that ability in the spell’s area.
