Character and campaign tools in NAT420

Keep your character and your next encounter together in one browser-based tabletop companion. Account tools require sign-in. Start anonymously, or create a free account to keep your characters; reading these guides and public pages does not require an account.

Build and print your character

Choose a starting class and receive suggested ability-score assignments from the standard array. You can override the suggestions, advance your character, track multiclass resources, review grants, and print a read-only character sheet.

Spells, equipment and campaign notes

Manage known and prepared spells, spell slots, separate inventory bags, currency, features and limited uses. Keep campaign progress and private journals with your character, then export a backup before importing or restoring data. Preview Torrii Between Tides, a complete original campaign with prepared characters, encounters, quests, NPCs, a map and session notes. Explore it without an account, make a private copy when ready, then prepare your own session. Use DM tools to start or resume your campaign. Use player tools for character creation and party participation. Both use the same account and tools. Learn how to track concentration and spell durations and organize campaign notes between sessions.

Encounters and battle maps

Roll attacks and initiative, group monsters, track hit points and conditions, and share an encounter through a party lobby. Dungeon Master controls support battle maps, doors, tokens and reusable CSV content packs. Follow the guide to prepare your first combat encounter.

Sharing that you control

Choose a character share code or share a limited read-only sheet with accepted friends. Joining a party also lets its enabled owner-DM read the selected character’s mechanics while the lobby is open. Private notes, journals and account details stay out of shared sheets. Character sharing and user-profile sharing have separate controls.

SRD reference

SRD reference information is available to every account. Use it alongside species, classes, backgrounds, spells, tools and equipment. See the sources page for attribution and the CC BY 4.0 license.

Use it on mobile or install it as an app

Use NAT420 on your phone or install it as an app. While connected, opt in on a trusted device and download the characters you need. Their saved sheets remain available offline, with limited local drafts for supported fields. Combat and party actions require a connection; reconnect and review changes before synchronizing. Follow the offline character-sheet setup guide before your session.

This service is for adults aged 18 and older. Nat420 is an independent tabletop companion; Dungeon Master rulings remain authoritative.
