MAGIC AND DIVINE FOCI
By permanently sacrificing one of his daily spell slots, any caster can create a magic focus that will be able to bring forth 1 particular spell 3 times per day, but always at the casting level of the creator when he made the item. The creation requires 100gp per level of the spell in material cost, plus some physical object into which the spell is placed and 1 week of time per level of the spell. If the caster should die, there is a 90% minus 5% per experience level that the focus will be destroyed with him. The focus can be used by characters of the same class as the creator, but will only function once per day.
As with scrolls, Tribal or impoverished spell casters can make a focus free of charge, but the time is increased to 2 months per level of the spell.
