Earth Tremor

From Xanathar's Guide to Everything, page 155; and Elemental Evil Player's Companion, page 17.

Description
1st-level evocation


 * Casting Time: 1 action
 * Range: 10 feet
 * Components: V, S
 * Duration: Instantaneous

You cause a tremor in the ground within range. Each creature other than you in that area must make a Dexterity saving throw. On a failed save, a creature takes 1d6 bludgeoning damage and is knocked prone. If the ground in that area is loose earth or stone, it becomes difficult terrain until cleared, with each 5-foot-diameter portion requiring at least 1 minute to clear by hand.

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.
