Amplify Voice

You amplify your voice loud enough to shatter eardrums and carry your voice across great distances. For the duration:

• During the 10 minute concentration, you can make your voice audible and intelligeble perfectly at long distances. The distance varies depending on the location and background noise, as determined by the DM, from 1 mile in heated combat up to 5 miles in the dead of night.
• As an action, including as you cast the spell, you can focus your voice into a damaging shockwave. Each creature in a 30-foot cone must make a Constitution Saving Throw. On a failed save, a creature takes 4d10 Thunder damage and is deafened until the end of your next turn. On a successful save, a creature takes half as mcuh damage and is not deafened.

At higher levels. When you cast this spell using a spell slot of 5th level or higher, the thunder damage increases by 1d10 for each spell level above 4th.
