Armenin's Complex Space

Using Armenin's understanding of pocket dimensions, you can generate copies of an area and design the means to access the next one.

As part of casting the spell, you must trace closed curves on a surface, defining an even number of "holes", these are called branch cuts. Once you're done, decide which of these are connected to which others to complete the spell, if you connect two cuts to the same the spell fails and arcane energy is released dealing 2*Nd12 (N = number of cuts) to anyone within 20ft. that doesn't succeed on a dexterity saving throw against your spell save DC (half damage on a save). Once the cuts are linked anyone can cross them to enter the next copy of the area from the linked cut, the number of copies you can create at once is equal to you spellcasting ability modifier +1.

If you cast this spell in the same place every day for a year and consume diamond dust for a total value of 250GP for each copy you're creating (7500GP for 9th level).

 At higher levels : When you cast this spell using a spell slot of 6th level or higher, the number of copies you can create is increased by a number equal to your spellcasting ability modifier for each level higher than 5th. Casting this spell at 9th level lets you create an infinite number of copies.
