This spell is used to protect some "hot" and vulnerable items, such as spellbooks, scrolls and material components. The wizard leaves these in a specially prepared place and then uses a small "linking device" to recall them to his current place.
The store must be created first. This is a chest of up to 4?3?3 foot size. It can have compartments or secret mechanisms and traps. The exterior must be crafted from pure obsidian and carved with scenes of the wizard's life. It costs a minimum of 5000 gp for the basic work. Regardless of the contents, the chest always weighs 15 pounds.
As long as they fit inside, spellbooks, maps, scrolls, potions, coins, etc., can be stored in the chest, with the exception of weapons: only one weapon can be stored. In addition, everything in the chest must have been in the property of the wizard for at least 24 consecutive hours before storage, otherwise the chest will not function at all.
Then the wizard must construct two identical "linking" devices. These can be almost anything but they must be made of metal. Usually they are something small and discreet, such as earrings or rings or bracelets. Their cost usually is around 3 gp each. The wizard then casts the spell on them and the chest. One of them fuses inside the chest, thus providing the necessary link with the other device.
From then on and for the spell's duration, the wizard leaves the chest in a presumably well guarded place and carries the second device, always in contact with his flesh (failure to do so ends the spell).
Three times per day, the wizard can summon the chest. He can then examine or alter the contents, use his spellbooks to memorise spells, etc. He can send the chest back to its hiding place or keep it, as he likes. Summoning and sending away the chest count as an action and require one round each.
The chest and the caster must be in the same plane of existence in order for the spell to work. The material components of the spell are the chest and the linking devices; the latter are consumed at the end of the spell.
A wizard can only have one such chest in operation at any given time.
