Bixby’s Workshop

With this spell, you create a 30 cubic foot extradimensional space and connect it to a gem (the material component).  Only one space can be created to a gem.

The space can be used to store non-living matter for an indefinite amount of time.  This spell can be used to store large projects and devices, and carry it along with the crafter.

In order to create the extradimensional space, a gem must be placed on the ground, and after the casting time (10 minutes, uninterrupted); the extradimensional space is created per the  caster's intent.  In order to enter the space, the spell must be cast again, after which the caster and one other living being can enter the space for up to 8 hours.  After 8 hours, the caster (and possible guest) are shunted from the extradimensional space to an unoccupied space adjacent to the gem, along with anything that is on the caster's (and guest's) person.

If the gems is moved more than 5 feet during the duration of the spell, the occupants are immediately shunted to an unoccupied space adjacent to the crystal. If there is no unoccupied space, the occupants take 2d8 force damage, and are shunted to the nearest unoccupied space.

If the gem is destroyed, the extradimensional space, and its non-living contents are immediately destroyed.
