Conjure Stairs

You conjure a set of stone stairs in a location you can see within range. You cannot conjure the stairs in a space occupied by a creature or other physical objects that would occupy the same space. They can be of any dimensions but must fit within a 30ft cube.

When you cast this spell using a spell slot of 2nd level or higher, the volume the stairs can occupy increases by a 10ft cube for every slot above 1st level.
