From D&D Wiki
|Casting time:||1 action|
|Components:||V, S, M (a mouse trap made of tin)|
|Duration:||Concentration, up to 1 minute|
You create a three-row toothed trap made of solid stone that springs right below a creature you can see in range. The trap is a 10-foot diameter cylinder that is 30 feet tall. A target that is completely inside the cylinder must make a Dexterity saving throw. On a failed save, the target takes 5d8 bludgeoning damage, and it is restrained for the duration of the spell. On a successful save, the target takes half as much damage and isn't restrained. A creature restrained by the trap can use its action to make a Strength check against your spell save DC. On a success, it frees itself.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd. If you cast this spell using a spell slot of 5th level or higher, the trap is a 15-foot diameter cylinder that is 40 feet tall. If you cast this spell using a spell slot of 8th level or higher, the trap is a 20-foot diameter cylinder that is 50 feet tall.
