Vatesh’ Pulse of Force

As the crystal shatters a pulse of force energy is released, that is a 60ft radius. Every creature you see as a threat must make a Constitution saving throw taking 6d10 force damage on a failed save as well as being knocked prone, or half as much on a successful save and are not knocked prone.

for every spell level above 5th you gain an extra 1d10 for casting the spell at 6th level or higher.
