The workshop

Prep before a table exists: the shelf, a workshop's hub and its fifteen tools, WorldForge, copies of published rules that play like the original, guided tours and per-tool guides, pick lists instead of typed names, bundles, and the Plugin tool that builds world packs.

A is a campaign that never plays. It has every content editor a campaign has, measured against a stand-in party you declare, and nothing to narrate. Build a world there once, then import it into as many campaigns as you like. Workshops, campaigns, characters and individual assets all clone.

A workshop's hub: cards for Storyboard, Party, Battle maps, Region, Encounters, Cast, Factions, Bestiary, Homebrew, Lore, Tables, Rules, Plugin and Share, each with a count
The hub of a workshop. Every card is a tool with its own tour and guide.

The shelf and the hub

on the home screen opens the shelf: your workshops with covers, plus prepared worlds from the that install as workshops. Opening one shows its hub, a card per tool with a count. A command palette (on a desktop) jumps to any tool or entry.

The tools

ToolWhat you make
The world as one document over the records the table plays: a Character is a cast member, a Location a place, a a faction. A wiki, a web of links (family trees, chains of command, as truth or as belief), a timeline with converting calendars, an atlas with pins and regions, secrets with their keepers, and a stub scan. Forge, Ask the world, Draft and Paint appear when the server has the AI for them. WorldForge files import and export whole, and the AI Dungeon Master is told each 's hidden truth and the secrets the party has not learned.
as beats and acts. A fight card uses the fight it picked, arrows can be one route of several or "only if", and a later board joins an arc already played as its next act. Imported into an AI campaign, it becomes the plan the Dungeon Master follows.
PartyThe stand-in target party and any , with a level mismatch warning.
The , and Map Editor. See Maps for dungeon masters.
RegionThe editor with imports and PNG export.
Monsters and placements with live difficulty against the party, hidden enemies, overrides, rewards, a private note, and a "How hard is this?" workbench.
CastNPCs with role, portrait, voice, gender, location (offered from the region map and geography ) and relationships. An NPC can fight as an stat block or one of your own.
FactionsStanding, goals and power, and who belongs.
Monsters from a catalogue pick or from scratch: the full stat block, a sectioned trait editor, spells known searched from the catalogue, passive perception derived in the right order.
Items (weapons, armour, magic items with every part of their magic), spells with the engine's whole mechanics, feats, backgrounds, species, subclasses, and hazards (traps, poisons and diseases the engine runs by name). Start from copies a published entry, marked Variant, and the copy plays at the table exactly like the original. A checker under the editor reads each kind against the SRD's norms, with a link to the rule's page.
Lore. See The binder.
Tables with x3 weights, rows that point at another table, a monster, an item or an NPC (picked from what the holds), nesting four deep, and draw without replacement.
Rules: house rules and the homebrew a ruleset ships.
PluginA built from this workshop, with , catalogue pickers, browser-resized pictures and a Publish tab.
ShareThe export, listing what it will carry.

Tours, guides and glossary

The shelf, the hub and every tool have a that runs once and can be replayed from Help. A tool's tour walks into its own editor where the work happens. Help inside the is a written guide per tool: what it is for, a first session in order, and the things people miss, with the tool you have open first. A glossary sits beside conditions, schools of magic, weapon properties, damage types, skills and alignments.

Pick from a list

Wherever a tool used to ask for the name of something that already exists, it now offers the list beside the field and still accepts typing: monster search in the workbench, a picker that writes table rows, links from a dropdown, tags you already use, an 's location from the , languages and conditions from their lists.

Bundles

Share writes a .odm-workshop.json with pictures inside; , , Market shops, the document and every link between the pieces travel too. A can draw on one shared workshop: its pickers list the shared cast, places, maps and fights, and the links stay live. Importing offers every kind as a tick. See Importing workshop prep.

The Plugin tool

One draft per . A guided identity wizard, builder tabs for races, classes, backgrounds, spells, items, features, monsters, , locations, hooks, a glossary and name seeds, pickers from the and the so no id is typed, Pull from this workshop to lift and in, pictures resized in the browser, and a Publish tab that runs the validator and downloads the manifest or installs it on this server (administrators only). The draft rides in the and through Duplicate. See Content pack and world packs for what a pack is.
