The battery spell allows the caster to store spell energy for use at a later time. The caster creates a temporary magic item called the battery. Within this battery, he can store one spell level per casting level. Charges (as these stored levels are called) are semi-permanent meaning that they will remain until dispelled. Anti-magic shells and similar magics will only negate the use of a battery while such are within their area of effect, the battery will not be dispelled.
Stored levels are withdrawn from the spells the priest has currently memorised, with the highest level spells being removed first. In other words, this spell is best cast when the priest is not expecting to be needing his high level spells. Using a bejuryl stone (or any other DM-chosen expensive object) of 1000 gp worth per charge to be stored (fourteenth level means 14 charges, which accounts to 14,000 gp), the priest casts this spell and then begins to power the battery by losing one spell level per hour (so the above gem would take 14 hours to charge) into the gem. Spells which are partially removed cannot be cast, and if the battery is fully charged with part of a spell remaining, then that partial spell is also lost. The charging process will never take more than 24 hours no matter how many charges are needed.
The charges are then stored within the gem and can be recalled at any time in the future. The caster must use the battery to cast his spells, and the charges can only be used to cast spells that the priest currently has memorised - it cannot be used to cast whatever spell the priest wants, and it certainly cannot be used to cast a spell outside the priest's allowed spheres. Any number of charges up to 7 can be withdrawn in a round, and any spell cast while using the battery remains in the priest's mind, and can be cast normally at a later date. Spells cast with the battery have a normal casting time, and all components (other than material) must be used. The battery takes the place of the regular material components, and is consumed when the last spell is released.
The caster can have only 1 battery in effect at one time, and when it is drained of charges it becomes a worthless glass sphere. Note that this spell can be used to power any spell of any level (which the priest can normally cast), but as its primary use is to allow the priest to recover spells whilst in an area which prevents this. Normally, only spells of higher than third level will be cast with the battery, as 3rd-level and lower spells can be regained by the priest without contact with his deity.
