Source: Dungeon Master’s Guide

You can take a Magic action to blow the horn, which emits a thunderous blast in a 30-foot Cone audible out to 600 feet. Each creature in the Cone makes a DC 15 Constitution saving throw. On a failure, a creature takes 5d8 Thunder damage and has the Deafened condition for 1 minute. On a success, it takes half damage only. Glass or crystal objects in the Cone that aren’t worn or carried take 10d8 Thunder damage.
Each use has a 20 percent chance of causing the horn to explode. The explosion deals 10d6 Force damage to the user and destroys the horn.
