Dungeon Master Tool
Everything core works without an account. You need one only to play online, publish to the marketplace, or download other users' content.
Worldbuilding 🗺️
- Era Timeline — Split your world's history into eras on a timeline bar and move between them. Each era keeps its own map, pins, nested location maps and day-by-day timeline pins linked to cards and sessions — the same city before the war and after it.
- Templates & Packages — Every world is built on a template (the D&D 5e template is built in) and pulls content from packages: bundles of cards you install into any world, link to other packages, or share on the marketplace. Custom templates are coming.
- Codex — Schema-driven cards for NPCs, monsters, spells, items, locations and more. Every reference is a tappable link; pin cards to the top, preview any card with a long press, and search by name, tag, category or text.
- World Map — Pins, grid and scale, drawing, fog of war, and nested maps you can walk into (districts, dungeons, taverns).
- Mind Map — Infinite canvas with linked nodes, workspaces, freehand drawing and undo/redo.
Running the Session ⚔️
- Second Screen — Give the table its own view: pop out a window onto a second monitor, cast to a TV or projector, or project into every connected player's app. Battle maps, images, cards and PDFs go out the way you choose; fog of war and hidden tokens stay hidden.
- Battle Map — The session screen is the map: encounter panel and event log sit on top. Layers, fog of war, AoE templates, 5e diagonal rules, creature-sized tokens, shapes and text, a DM-only layer, hidden tokens, movement trails for the round, and two maps joined into one.
- Combat Tracker — Initiative, HP (with hit-dice rolls), conditions, turn order and an event log; right-click a token to add a condition or remove it.
- 3D Dice — Dice roll across the screen with named styles; skills and saving throws roll from the character sheet with one tap.
- Soundpad — Layered ambience with gapless loops, fades and ready-made soundpacks.
- PDF Library — PDFs kept inside the world, opened in tabs, shareable with players.
Characters 🎲
- Full 5e rules — Species, class, subclass, background and feats fold into one sheet: senses, resistances, proficiencies, traits and always-prepared spells, each showing where it came from. Multiclass prerequisites and spell slots, class resources (Rage, Bardic Inspiration, sorcery points…), weapon mastery, short and long rests.
- Character Builder — Species, class, subclass, background, ability scores, skills, starting equipment and feats from the SRD and any installed pack.
- Level-Up — Automatic HP, proficiency bonus and hit dice; ASIs, feats, subclass and spell picks wait as pending choices.
- Sheet — Jump to any section; import a character from another world.
Playing Online 🌐
- Online worlds — Put a world, package or character online and it stays the same on every device you sign in on. A multiplayer world's pictures live in the cloud, so players see them even when the DM is offline.
- Players — Join with a revocable invite code, claim a character, move your own token on your turn, and send dice rolls to the DM's log. Shared cards update when the DM edits them.
.dmtz files — Export a world, package or character to one file and import it anywhere, no account or network needed.
Content 📦
- SRD 5.2.1 — Built in and available offline; optional when you create a world. SRD text can be shown in Turkish, with its own language setting.
- 19 one-tap packs — Tome of Beasts (1–3, 2023), Creature Codex, Monstrous Menagerie, Black Flag SRD, Deep Magic, Tome of Heroes, Vault of Magic, Tal'Dorei and more.
- Ready-made worlds — 99 Devils of Uzrah's Palace (Shadowdark), Army of the Damned, The Cold Bounty, and our own Turkish campaign Aegis Act 1.
- Marketplace — Publish worlds, templates, packages and characters as versioned snapshots with content previews, an official filter and an 18+ rating.
- Social — Profiles, follows, activity feed, direct and group chats, game listings with applications.
