Urrchyn’s Palace of Paragraphs

You create 2 5ft by 5ft by 5ft cubes made of magical paper with many arcane poems on them. The walls must both be in range and be directly connect at one face. You may place one wall on top of the other. Each wall has 3 hit points.

At higher levels. For every spell level above 1 the hit points go up by 3. (6 at 1st level, 9 at 2nd, 27 at 9th level.)
