Ode of the Ancients

You strike your percussion instrument with a resounding force, releasing a powerful, ancient melody that echoes through the battlefield. All enemy creatures within a 30-foot radius of you must make a Constitution saving throw. On a failed save, a creature takes 6d6 Thunder damage, or half as much damage on a successful save.

At the same time, all allied creatures within the same radius are healed for half the total Thunder damage dealt by this spell. The healing spreads as the sound of your instrument reverberates through the air, restoring vitality to those who hear it.

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