Control Snow

Until the spell ends, you control any loose snow and ice inside an area you choose that is a cube up to 100 feet on a side. You can choose from any of the following effects when you cast this spell. As an action on your turn, you can repeat the same effect or choose a different one.

Raise Snow. You cause the freestanding snow and ice to rise by as much as 30 feet. An area 10 feet in width along the outer edge of the raised area becomes difficult terrain, as the slope hinders movement. The snow collapses after the spell ends.

Snowdrift. You create an unstable wall of snow 20 feet in height and and cause it to crash down on one side. All creatures in that area need to succeed on a strength saving throw or be knocked prone and take 2d8 bludgeoning damage. On a success they don't get knocked prone and take half damage.

Sculpt Snow. You can displace and form the loose snow and ice in the area. When you do this, you can choose to form the displaced snow into crude but solid objects or structures. You can displace and form any snow that fits within a 15 feet cube at a time. The movement of the snow is instantaneous, but doesn't have enough force to cause harm.

Snowfall (Light). You cause light snowfall in the area. The area becomes lightly obscured.

Snowfall (Heavy). You cause heavy snowfall in the area. The area becomes heavily obscured. For each minute that this effect is active, 1 foot of snow accumulates in the area.

Minor Avalanche. You cause a directional movement in the snow. You can either direct this movement towards any of the edges of the area, or towards the center. You can choose areas to exclude from this effect.

Each time a creature starts its turn inside of the minor avalanche, it needs to suceed on a strength saving throw, or be knocked prone, take 2d8 bludgeoning damage and be moved 10 feet in the chosen direction.

A creature knocked prone this way is also blinded and restrained and has total cover as it is being buried in snow. A creature can use its action to burrow out of the snow and remove these conditions by succeeding on an Strength (Athletics) check contested by your spellcasting DC. The creature gains one level of exhaustion for every 5 minutes it spends buried in the snow.

When a creature arrives at the end point of the chosen direction, it stops moving, but continues to take damage.
