Empowered roar

Each creature within 10 ft. of you must make a strength saving throw with your spellcasting DC. On a fail, the creature takes 2d10 force damage, is pushed away 10 ft. and knocked prone. If the creature succeeds the saving throw, it takes half damage and doesn’t suffer from any other effects of the spell.

At higher levels. For each level above spell level 2, add 5 ft. push distance.
