Tamaz’s Tumultuous Blizzard

A section of the weather changes in a 20-foot-radius, 40-foot-high cylinder centered on a point within range. The caster then speaks a command word to control the weather, being ak to change the type of weather and the effects already there by speaking another command word as a bonus action.

Snow: a vicious snowstorm rages through the area making it hard to see past 5ft needing a successful Perception check to see past 5ft, and at the start of their turn they must make a constitution saving throw or take 2d8 cold damage, half as much on a success.

Ice: sleet and ice falls from the sky making the floor in the radius slippery and wet, whenever someone moves more than 5ft in this radius they must make a dexterity check, on a failure falling prone and taking 2d8 bludgeoning damage.

Hail: hail falls down from the sky and on the start of their turn each creature in the cylinder must make a constitution saving throw. A creature takes 2d8 bludgeoning damage and 2d6 cold damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the radius area and cylinder height increases by 5ft and d8 damage increases by 1d8.
