You create a 10-foot radius pit with a depth of 10 feet at a point on the ground that you can see within range. The cylindrical space within the hole exists on a different plane, so it can't be used to create open passages. Since it extends into another dimension, the pit has no weight and does not otherwise displace the original underlying material.

When the pit appears, each creature within its area must make a Dexterity saving throw. On a failed save, a creature falls into the pit, falling prone and taking falling damage as normal. On a successful save, the creature is pushed 5 feet to the nearest space out of the pit's space. In addition, the edges of the pit are sloped. When a creature enters the area on the ground within 5 feet of the pit's opening for the first time on a turn or starts its turn there, the creature must succeed on a Dexterity saving throw or fall into it. 

A creature within the pit can exit the pit by climbing out of it by making a successful Strength (Athletics) ability check with a DC equal to your spell save DC. When the spell ends, creatures within the pit rise up with the bottom of the pit until they are standing on the ground.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can increase the depth of the pit by 10 feet for each slot level above 2nd.
