Word bomb

You create a ball of compressed words in your hand. The ball emits quiet whispers while sitting still. You may throw the ball causing it to explode on impact dealing 1d6 Thunder damage to all creatures within 10 ft. The ball knocks back any small objects in its area that aren’t being worn or carried when it explodes. The explosion creates a combination of sounds based on the words used to create the spell that can be heard from up to 300 ft away.

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
