Nat20 is a beautifully crafted character companion for tabletop RPGs built for players who love the craft of a well-kept character. One elegant app for D&D 5e (2014 & 2024) and Pathfinder, with all the math handled for you and your whole campaign kept close. FORGE YOUR HERO A guided creation wizard walks you through every roster across three rulesets — 37 ancestries, 40 classes, and 37 backgrounds. Roll for stats, use point-buy, or drop in the standard array. Whether you're rolling your first character or your fortieth, every step is explained. A LIVING CHARACTER SHEET A six-tab codex — Stats, Skills, Combat, Spells, Items, and Lore — with real ability math, AC, saves, and proficiencies computed for you. Level up and watch everything recalculate. No spreadsheets, no second-guessing the rules. THE FULL SPELL LIBRARY Nearly 800 spells across three rulesets, searchable and filterable by level. Prepare your slots and cast right from the sheet, with usage tracked as you play. CHRONICLE EVERY ADVENTURE Every level-up, hit taken, potion drunk, and spell cast is logged in a session-by-session journal of how your hero changed over time. An on-device AI weaves it into a written chronicle of your legend — running entirely on your device. PRIVATE & OFFLINE No account. No tracking. Your characters live on your device and sync privately across your own iPhone and iPad through iCloud. Everything works completely offline — at the table, on the train, anywhere. CRAFTED FOR THE TABLE • Built natively for iPhone and iPad • Light parchment and candlelit dark themes • D&D 5e (2014), D&D 5e (2024), and Pathfinder in one app • Game content based on the System Reference Document Forge your hero. Chronicle every adventure.
