Grimlore's Grimoire
2-level Evocation
The ground freezes in a 10-foot-radius sphere centered on a
point you choose within range. Any creature that starts its
turn or moves into the area for the first time must make a
Constitution saving throw or take 2d8 cold damage and gain
one level of exhaustion. On a successful save, a creature
takes half as much damage and does not suffer exhaustion.
Creatures resistant or immune to cold damage automatically
succeed on the saving throw.
At higher levels: When you cast this spell using a spell
slot of 3rd level or higher, the damage increases by 1d8 for
each slot level above 2nd
