From publisher blurb: Unusual Core Classes: The Spellweaver presents an alternate magic system that relies on the caster’s skill more so than just about anything else. Using the new Spellweaving skill, the Spellweaver is able to manipulate the threads of magic that cover existence like an infinite web of arcane energy. Spells of any level may be cast so long as the character is willing to risk the repercussions of failure, repercussions that can prove to be more hazardous with more powerful spells or when failing magic of a particular type.
