FAQ
How detailed are the generated spellbooks?
Each spellbook includes a narrative overview, spell list with level breakdowns, unique signature spells, safety warnings, marginalia, lore snippets, and plot hooks. You can expect enough content to fuel multiple sessions of D&D, Pathfinder, or other fantasy RPGs without additional writing.
Can I customize the spells and lore after generation?
Absolutely. Use the optional instructions field to guide the AI up front, then edit the saved result to tweak spell effects, adjust DCs, or rewrite lore beats. Many storytellers generate multiple versions of the same tome to explore different outcomes, patron bargains, or campaign branches.
Does the tool work for non-D&D systems?
Yes. While the presets cover D&D 5E, Pathfinder 2E, and other mainstream games, the narrative output is system-agnostic. You can adapt terminology for 13th Age, Dungeon Crawl Classics, or bespoke homebrew systems. Include instructions specifying the mechanics you need and the generator will follow your lead.
How should I share the spellbook with my players?
Export sections into PDF, Google Docs, or your virtual tabletop of choice. Many GMs hand players a curated excerpt while keeping advanced chapters hidden until the party unlocks them. You can also turn the marginalia into puzzles, ciphers, or physical props using tea-stained paper and wax seals.
