1st-level Spell: Earth Rumble

Sorcery (Transmutation)

You cause the ground immediately around you to shake and roll. Every other creature within 10 feet must make a Dexterity saving throw. On a failure, a target takes 2d6 bludgeoning damage and is knocked prone. On a success, it suffers half as much damage and no other effects. If the terrain is dirt or stone, it becomes difficult terrain for all other creatures besides you for the next hour.

• At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st, and the radius increases by 5 feet for each two slot levels above 1st.
