You create an invisible 10 foot cube of dreadful, immaterial weight within range that prevents any enemies’ passage as if occupied by a large creature allied with you. This spell’s effect is subject to dispelling like any other spell, but cannot be physically grappled, shoved, or moved in any way, and is immune to all damage. It permits passage to any creature allied with you, but does not allow enemies to move through its space.
Although the spell's tangible effects are naturally invisible, they cast a shadow that appears to be a large dragon upon the ground. Any spell or ability that allows a creature to see magic can see the outline of a dragon filling the space and grappling with any creature beneath it, but any spell or ability that allows a creature to see invisible creatures reveals nothing in the space.
When you cast the spell, or any time a creature starts its turn inside the cube, a creature in the cube must make a Strength saving throw or be knocked prone and restrained. Any creature that makes their save or is allied with you is shoved into the nearest open space outside the cube. On your turn, you may move the cube up to 60 feet in any direction as a bonus action, but the spell ends if any part of the cube is beyond the range of the spell from you after you move it.
Any creature that is immune to fear is also immune to this spell's effects.
At Higher Levels: This spell's cubic area increases by 5' when you cast it at 5th level (15 foot cube), 7th level (20 foot cube), and 9th level (25 foot cube).
