This spell requires an expensive gem. The value of the gem depends on the number of spell levels that will be cast into the gem. The gem's value must be 5000 gp per spell level of the spell or spells (cumulative).
This spell causes a gem to have a flame appear at the centre. The flame has no real significance other than that the gem is ready to receive spells. After a spell is cast into a gem it can be called forth in one tenth of a round. The spell will act at the level it was cast into the gem. The gem is destroyed in the process.
A spell that is going to be placed into a fire gem must be equal to or less than the wizard's level divided by four, rounded down. An 18th-level wizard could put up to a 4th-level spell into a fire gem. A 24th-level wizard could put up to a 6th-level spell into a fire gem.
If permanency is used on a fire gem, it will allow the spell to be cast a number of times per day. To determine how many times the spell or spells can be cast, divide the wizard's level by five times the level of the spell, i.e., a 1st-level spell cast into a fire gem at eighteenth level will be able to be cast 18/5 or 3 times a day. If a conduit spell is added before the permanency it will double the effects of the spell (if appropriate) and double the number of uses per day.
Remember that a permanency and a conduit spell are a total of 19 spell levels. Therefore a conduit, permanency and magic missile would require a gem costing 20?5000 = 100,000 gp gem. Also the wizard would be unable to cast spells for 20 days (due to the effects of the conduit).
