Domain Expansion: Furious Flora

A sphere of power ripples out in a 60-foot-radius sphere from a point within range. Each creature in that area must make a Nature saving throw. If they get lower than a 3, they die instantly and get dragged into the earth. If they get lower than a 10, they take 3d6 bludgeoning damage, or if lower than a 15, 1d6.

At Higher Levels. When you cast this spell using a spell slot of 4th or higher, the insta-kill effect takes effect at a lower than 6 roll rather than 3, and the damage rolls add a 2d6 to them. Subsequent levels add 3 to the insta-kill effect and 2d6 to the damage effects.
