4th-level Spell: Wall of Snow

Sorcery/Whispering (Conjuration)

A supernatural wall of snow springs into existence on a solid surface you can see within range. The wall is 12 inches thick and is composed of ten 10-foot- by-10-foot panels. Each panel must be contiguous with at least one other panel.
If the wall cuts through a creature's space when it appears, the creature is pushed to one side of the wall (your choice). If a creature would be surrounded on all sides by the wall (or the wall and another solid surface), that creature can make a Dexterity saving throw. On a success, it is pushed outside of the wall to a space of its choice.
The wall can have any shape you desire, though it can't occupy the same space as a creature or object. The wall must be vertical and rest on the ground. It is an object made of packed snow that can be damaged and thus breached. Each panel has AC 10 and 100 hit points, and is vulnerable to fire damage. Reducing a panel to 0 hit points destroys it and might cause connected panels to collapse at the GM's discretion.
The wall radiates intense cold, and blasts of snow explode outwards when it is damaged. Creatures that are within 5 feet of a wall panel when it is damaged take 1d6 cold damage, and must succeed on a Constitution saving throw or become restrained until the start of their next turn.
If you maintain your concentration on this spell for its whole duration, the wall becomes permanent, mundane, and can't be dispelled. Otherwise, the wall disappears when the spell ends.
