Starjammer Core Rulebook (Pathfinder)

Revolutionary Modular Magic System for Pathfinder

Spheres of Power completely reimagines magic in Pathfinder RPG with a flexible, talent-based system that puts you in control. Instead of preparing spell lists, you build your caster by selecting magical spheres and talents, creating truly unique spellcasters that can compete with martial characters at every level.

What's Included

• 20 Magic Spheres: Alteration, Conjuration, Creation, Dark, Destruction, Divination, Enhancement, Fate, Illusion, Life, Light, Mind, Nature, Protection, Telekinesis, Time, War, Warp, Weather, and more
• New Casting Classes: Elementalist, Eliciter, Fey Adept, Hedgewitch, Incanter, Mageknight, Shifter, Soul Weaver, Symbiat, Thaumaturge
• Casting Traditions: Customize how your magic works with drawbacks and boons
• Sphere-Specific Talents: Hundreds of options to personalize your magical abilities
• Archetypes for Core Classes: Convert wizards, sorcerers, clerics, and more to the Spheres system

Why Spheres of Power?

Traditional Vancian magic can feel limiting and unbalanced. Spheres of Power solves this by giving you at-will magical abilities that scale with your level, plus a pool of spell points for enhanced effects. Build the exact caster you envision - a pyromancer who only controls fire, a healer focused purely on restoration, or a versatile generalist. Every choice matters, and martial-caster balance is maintained throughout all 20 levels.
