Erikron's Conjure Ice Pit

You create a 10-foot-by-10-foot extradimensional hole with a depth of 30 feet deep. You must create the pit on a horizontal surface of sufficient size. Since it extends into another dimension, the pit has no weight and does not otherwise displace the original underlying material. You can create the pit in the deck of a ship as easily as in a dungeon floor or the ground of a forest. Any creature standing in the area where you first conjured the pit must make a Dexterity saving throw to jump to safety in the nearest open space. In addition, the edges of the pit are sloped and covered with ice, and any creature ending its turn on a square adjacent to the pit must make a Dexterity saving throw with disadvantage to avoid slipping over the edge and falling into the pit. Creatures subjected to an effect intended to push them into the pit (such as bull rush) do not get a saving throw to avoid falling in if they are affected by the pushing effect. Those that fall into the pit take bludgeoning damage as per the falling rules detailed in Chapter 8 of the players handbook (1d6 damage per 10ft. to a maximum of 20d6). Characters fall prone unless they have some way of negating the falling damage. The pit’s coarse stone walls are covered in a layer of ice and have a Strength (Athletics) DC of 20 to climb out of the pit. When the duration of the spell ends, creatures within the hole rise up with the bottom of the pit until they are standing on the surface over the course of a single round.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the pits depth increases by 10ft. per higher level slot used to a maximum of 110ft. at level 9. Also when you cast this spell using a spell slot of 4th level or higher the pit has a 5ft. deep pool of icey water at the bottom that does 2d6 cold damage per round of immersion, this damage increases by 1d6 per higher slot used above 4th level. Cold damage is halved on a successful Constitution saving throw. The liquid is yielding and does not break the fall.
