Eidolon’s Thundershock

A sudden force emanates from a point of your choosing that you can see within range, expanding quickly into a mighty clap of thunder. Each creature in a 20-foot-radius centered on that point must make a Dexterity saving throw. A target takes 8d6 thunder damage on a failed save, or half as much damage on a successful one. In addition, on a failed save, they are stunned for 1d4 rounds.

The sound from this blast can be heard by creatures within 1 mile, alerting all to your presence.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 and the amount of time stunned increase +1 for each slot level above 3rd.
