Elemental Maw

You call up a spinning vortex of elemental energy that inexorably draws everything around it toward seeming destruction. The vortex is a large sized object that cannot be hit, and may share its space with any number of creatures. When a creature moves within 30 feet of the vortex for the first time on a turn or starts its turn there, it must make a Strength saving throw or be dragged 15 feet closer to the center, taking 5d10 damage of a type, that you choose when you cast this spell, from the following list: acid, cold, fire, lightning, thunder, or poison. On a successful saving throw, the creature is not pulled in, and takes half damage.

At Higher Levels. When you cast this spell at 8th level and or higher, the spell deals an additional 1d10 for each level above 7th.
