Disperse Energy

You drain all of the energy in a 60 ft sphere at the target point. All living things and all objects vulnerable to temperature change must make a Constitution save (if they can make one) against the caster's spell save DC, taking 20d6 Cold damage on a failed save or half as much on a successful one. The environment in that area is completely frozen at a temperature slightly above absolute zero.

The energy drained from that area is concentrated and dispersed violently outwards, rapidly heating up the area in a up to 60 ft away from the edge of the original AoE. This extreme increase in heat causes the ground to melt and all foliage and animals not immune to Fire damage to instantly combust. Creatures in this area must make a Dexterity saving throw or take 20d6 Fire damage or take half as much on a successful save.

Any creatures that enter this area or start their turn in it for up to 30 minutes after the spell is cast will take 4d6 Fire damage in the outer sphere and/or 4d6 Cold damage in the inner sphere.
