Stone of planar stabilization
A fist-sized isometric cube of pure graphite. A protective fitted leather pouch with laces allows attachment to belt or exterior of pack.
Because graphite is highly anisotropic to electromagnetic and sonic vibrations, the presence of a sufficiently sized pure cubic sample produces a polarization effect in the space-time of any localized extradimensional space such as a portable hole or bag of holding.
While such polarization occurs, any creature within ten feet of the stone may concentrate on the gravitational field distortions in order to become gravitational neutral and buoyant as long as they maintain concentration.
The gravitational polarization allows two extradimensional spaces to be positioned in a nested, overlapping, or touching position without invoking the typical mutually assured destruction. Additionally the gravitational distortion causes that space and it's contents to weight half of its regular weight, and causes the boundary layer to become permeable to air, removing the risk of suffocation.
An attempt to overlay the cube with two extradimensional spaces is a delicate matter requiring a successful DC 20 Dex check. Upon failure, both extradimensional spaces are destroyed in the usual manner.
A successful placement remains stable for 12-24 hours (d12+12), after which time it suddenly experiences catastrophic failure, scattering all extradimensional containers and their contents randomly in a 100 foot radius. (Ites may end up in already occupied space, they are placed there from another dimension, not blasted from the location within the physical plane)
Removing the overlap is strongly recommended before 12 hours, but is a trivial matter of extricating the two extradimensional spaces, then removing the cube. This does not require a Dex check. A DC 5 WIS check may come into play for timing the removal in time.
