Canary Cry

Until the spell ends, whenever you say anything, a concussive scream erupts at a huge volume, from your mouth in a 5-foot-wide, 60-foot-long line. Each creature in the line must make a Constitution saving throw. On a failed save, a creature takes 6d8 thunder damage and is deafened until your next turn. On a successful save, it takes half as much damage and isn't deafened by this spell. Undead and oozes have advantage on this saving throw.

The force of the scream causes all torches and flames in its range to be extinguished, and any creatures of small or smaller size are knocked prone. 

After the spell ends you are unable to speak for 1d4 hours.
