Six Demon Bag
Contains: "Wind, fire, all that kind of thing."
A Six Demon Bag is similar to a Medicine Bag. It contains powerful reagents, fetishes, and other user-specific talismans that have been previously prepared by the owner in order to help focus and enhance their spells.
When a spell-caster uses their personal Six Demon Bag, they cast all spells as if one level higher, for purposes of duration, range, and effect. It does not allow a caster to cast higher level spells than they are normally capable of casting.
The cost to make a Six Demon Bag is figured: Character Level x Highest Spell Level Available To Caster x 500 gold pieces.
A Six Demon Bag has to be completely remade from scratch (at full cost) upon attaining a new level that allows access to a new higher level of spells.
