A unified, point-buy, d20 system. It lets you build and advance races, templates, characters, birthrights, archetypes, deities, party templates, martial arts, relics, character disadvantages, power packages, metamagic, item creation, channeling, epic spells, and a wide selection systems for magic and psionics, for any setting - including fantasy, modern, cyberpunk, futuristic, superheroic, and historical realms - using a single unified mechanic so that your characters are fully compatible and transferable. It discards classes, prestige classes, and the usual pile of sourcebooks - while remaining fully compatible with 3.0, 3.5, Modern, Future, and the vast majority of other d20 sourcebooks on the market. Part II covers how to use Eclipse with more than four hundred detailed examples of how to build all of those things, as well as detailed breakdowns of the standard classes.
