The Spellweaver

This fantasy roleplaying supplement introduces a skill-based magic system in which characters manipulate the threads of an arcane Weave. Spellcasters can attempt spells of any level by making Spellweaving checks, with failure carrying hazardous consequences, and included tables provide DCs for converting existing spells. The supplement includes a Spellweaver base class, four archetypes, four prestige classes, new feats, spells, magic items, a race, deity, cleric domain, creatures, hazards, and rules for abnormal Weave regions. It also provides conversion notes for existing feats and spells, along with printable, bookmarked PDF versions and a spreadsheet for calculating spell DCs.
