Extradimensional Pocket

This spell allows the priest to create a single extradimensional space or pocket like the one inside a bag of holding. The spell must be cast on a container such as a sack, bag, or backpack. Once under the influence of the spell, the container opens into a nondimensional space and is much larger inside than its outside dimensions. The container always weighs a fixed amount, regardless of what is put inside. This weight and the capacity of the extradimensional space depend on the level of the caster:

Level	Apparent Weight	Weight Cap.	Volume Cap.
9-13	15 lbs	250 lbs	30 cu.ft.
14-16	25 lbs	500 lbs	70 cu.ft.
17-19	35 lbs	750 lbs	100 cu.ft.
20+	60 lbs	1,000 lbs	150 cu.ft.

If the container is overloaded or if it is pierced by a sharp object, the bag immediately ruptures and the contents are lost into the Astral plane. Any items within the bag when the spell duration ends are also lost in the Astral plane.

Material Components

The platnum sheet must be inscribed with a drawing of a Klein bottle (a paradoxical figure with only one Surface — the three-dimensional analogue of the Moebius strip). The diamond dust is consumed during the casting — the platinum sheet is not.
