Ritual Spellcasting Rules:<br/><br/>All magic spells and psionic powers can be applied via the process of ritual magic.  A well trained individual can cast many spells ritually, even with minimal normative spellcasting talent.<br/><br/>Casting any ritual spell requires a ritual schema.  Ritual schemas most commonly take the form of scrolls, or carefully engraved dragonshards, and may be manufactured for half the market value of a scroll of the equivalent spell.  Schemas may only be used to perform a ritual, and even someone who knows the equivalent spell cannot copy a scroll from a schema.  Once used, the ritual schema crumbles into dust.<br/><br/>Anybody with access to proper sources of arcane information can create a ritual schema by making a Knowledge check with a difficulty equal to 10 less than the spellcasting DC of the ritual spell.  This process takes 24 hours, or 6 hours for someone with the scribe scroll feat.  Item creation feats can also reduce the time and cost involved.  The time needed to scribe a schema need not be spent all at once, but no more than a week must pass between the start and finish of creating the ritual schema.<br/><br/><br/>Ritual Magic is divided into five major categories.  Gutter Magic, Mortal Magic, Giant Magic, Dragon Magic, and Divine Magic.  The categories are so named after the beings that can draw upon them.<br/><br/>Gutter Magic:<br/>Spell Level 0-1<br/><br/>Legality: Legal to use unlicensed anywhere.<br/><br/>Resources to Research: A decent sized book collection will do.  Most nobles keep such a collection around, and any self respecting magician has the necessary books to do gutter magic research around.<br/><br/>Cost of a Library: 1,000 gp<br/><br/><br/>Mortal Circle Magic:<br/>Spell Level 2-3<br/><br/>Legality: Requires a licence costing 500gp to use in urban areas, violations typically carry a fee of 250gp x spell level.<br/><br/>Resources to Research: A well stocked library is needed, but still within the reach of a private individual.  Most cities with a population over 5,000 have the necessary library, and the nation of Aundair has a sufficient library in all of its settlements with a population of over 1,000.<br/><br/>Cost of a Library: 25,000 gp<br/><br/><br/>Giant Circle Magic:<br/>Spell Level 4-6<br/><br/>Legality: Requires a license costing 3,000 gp to cast spells in rural areas, and a special permit costing 1,000 gp to cast a spell in inhabited areas.  Most permits are issued for one spell on a case by case basis, or rarely for casting a single spell repeatedly.  Violations carry a fee of 5,000 gp x spell level, and irresponsible giant circle magicians can be imprisoned in a sanitarium for the rest of their natural lives.<br/><br/>Resources to Research: The resources of a major university are needed to cast magic of this magnitude.  Most cities with a population of over 100,000 have such a university.  An outsider with hit dice of at least twice the level of the spell and an intelligence of 12 or higher can also impart knowledge of how to cast giant circle magic.  Ruins in Xen'drik often contain inscriptions that can be used to research rituals to cast giant circle spells.<br/><br/>Cost of a Library: 500,000 gp<br/><br/><br/>Dragon Circle Magic:<br/>Spell Level 7-8<br/><br/>Legality: Casting dragon circle magic is illegal in urban areas, and requires a special license costing 15,000 gp to cast in rural areas.  A spellcaster casting dragon circle magic within national territory must still purchase a permit costing 2,500 gp for each casting, to insure against possible damages.  Violations are a capital offense.<br/><br/>Resources to Research: Dragon circle magic is beyond the ken of most mortals.  Only two places in Khorvaire might be able to scribe Dragon Circle Magic.  The Library of Korranburg, and the Cloudpeak Academy.  The dragons of Argonessen have access to a great deal of Dragon circle magic, and it can also be explained by outsiders of 14 HD or higher with an intelligence of 18 or greater.<br/><br/>Cost of a Library: 4 million gp<br/><br/><br/>God Circle Magic:<br/>Spell Level 9+<br/><br/>Legality: Strictly illegal everywhere without special order of the local ruler.  Violations are a capital offense that could lead to being declared an international enemy of the peace.<br/><br/>Resources to Research: God circle magic can only be learned by the most difficult and desperate of means.  The only place on Khorvaire where it could possibly be learned is in the direct presence of the Silver Flame.  Outside of Khorvaire, it may be feasible to learn God Circle magic in a library, but getting access is a trial in itself.  Beings of 20 HD, such as Solar Angels, Fiend Lords, the Daelkyr, and Dieties themselves can teach God Circle Magic.<br/><br/>Cost of a Library: priceless
