Eagle's Cry

A shriek of deep pain and fury escapes your lips. Each creature in a 60 foot cone must make a Constitution saving throw. On a failed save a creature takes 8d8 thunder damage and is stunned until the end of its next turn. On a successful save a creature takes half damage and is not stunned.

The shriek is audible from 300 feat away.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
