Arcane Maelstrom

A swirling mass of arcane energy appears in a 45-foot radius centered on a point you can see within range. The point can be on the ground, in a body of water, or in the air. Until the spell ends, that area is difficult terrain, and any creature that starts its turn there must succeed on a Constitution saving throw or take 8d6 force damage, 4d6 lightning damage, and 4d6 fire damage and be pulled 10 feet toward the center.

If a creature ends its turn within 30 feet of the center, they suffer one point of exhaustion.  If they reach the center, they must make a death saving throw at disadvantage.
