High-Level Magic
4.1 High Level Spells
Magic is common, but not high level magic — most high level wizards are either dead or have better things to do. Arcane spells above 4th level require research in order to learn. Spells from alternate sources will be slightly more expensive as a result of their obscurity.
4.2 Spell Components
Spell components are not an issue for spells 4th level and lower — components with a gold piece value will still be consumed but lesser components are negligible. For spells 5th level and above, spell components become more rare. Characters must make an effort to track down and use them, and keep track of them in their inventory.
4.3 High Level Magic Items
Magic items which require a 5th-level spell to create cannot be found on the open market. The buyer must supply the spell to an artificer who will make the item, or craft it themselves.
