Ensnaring Snow

You create a magical pitfall trap disguised by a thin layer of snow and ice in a 10 foot wide, 10 foot deep cylinder in range. If the trap is made in an area where snow and ice are already on the ground, the trap is imperceptible, and creatures must make an Intelligence (Investigation) check against your spell save DC to discern its presence.

When a creature enters the spell's area for the first time or starts its turn there, it must succeed on a Dexterity saving throw or fall into the pitfall trap, taking fall damage, and is restrained by the ice and snow as it collapses around them. The creature can make Strength saving throws at the end of each of its turns to free itself from the trap, climbing out of the hole into the nearest safe unoccupied space.

After the trap is triggered, the spell ends when no creature is restrained by it.
