Unendurable Frenzy

Yellow frenzied flame bursts from your eyes as you concentrate onto an area where the flames spew forth. You can move while concentrating on this spell. Every round after the first, you must succeed a DC10 Wisdom saving throw, or your concentration is broken and you become stunned. You cannot break concentration on this spell yourself.
All creatures within this spell's range take 2D8 psychic damage every round. Targets must make a DC10 Wisdom saving throw. On a failed save, targets become stunned.

Add an additional 1D8 psychic damage for each spell level above the 3rd level.
