Spheres of Power (PF1)
A talent-based magic system for Pathfinder and other d20 fantasy games, replacing spell levels, spells per day, and spell slots with at-will abilities and a ki-like pool of Spell Points. Players build casters around 20 magic spheres, with options ranging from elemental manipulation and shapeshifting to divination, illusion, and time magic. The book includes 11 new base classes, casting traditions, feats, magic items, NPCs, guilds, sample settings, and rules for rituals, spellcrafting, advanced talents, item creation, and incantations. The system can run alongside standard magic or replace it entirely.
