Umberlee's Rage

As a result of your ties to Umberlee, you are imbued with her rage and spite, and can react violently when damaged.

You point your finger at a creature that damaged you, and water from the nearest water source (even if it's the moisture in the air around them) coalesces into a pressure bubble around them, enveloping and squeezing them. The creature must make a Dexterity saving throw. It takes 3d8 water damage (bludgeoning) on a failed save, and is knocked prone. On a successful saving throw, it is not knocked prone, and takes half as much damage. Cast as 2nd level racial ability (3d8 total damage)

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d10 for each slot level above 1st.
