Rules

The Rules page is your campaign's reference book. Game Masters can write up homebrew rules, house rules, or session‑zero agreements and organise them by category so the whole party can find what they need.

Rule content supports Markdown, so you can use headings, bold, italic, lists, tables, and more to keep everything well‑structured and easy to read.

Tip: Looking for a place to store campaign‑specific details like starting items, lore, or world info? Check the Info page instead. Rules is best for gameplay mechanics, while Info is for campaign flavour and world details.

Markdown Support

The content field for every rule uses Markdown with GitHub Flavoured Markdown (GFM) support. This means you can write:

Headings

# / ## / ###

Bold & Italic

**bold**, *italic*

Numbered & bullet lists

1. / - / *

Tables

| Header | Header |

Strikethrough

~~removed~~

Links

[text](url)

The content textarea uses a monospace font so you can see your formatting as you type. The rendered output appears on the rule card once saved.

Creating a Rule

GM only

Click "Add Rule" to open the creation dialog. Fill in the following:

  • •Title (required): the name of the rule.
  • •Category : a free‑text label (e.g. "Combat", "General", "Magic"). Rules are grouped by category on the page.
  • •Content (required): the rule body. Supports Markdown for rich formatting.
  • •Order : a number that controls the sort order within a category. Lower numbers appear first.

Categories & Ordering

Rules are grouped by category on the page. Within each category, rules are sorted by their order value (lowest first), then by creation date.

Categories are free‑text, so you can name them whatever makes sense for your campaign. If two rules share the same category name, they appear together under that heading.

Table of Contents

The Rules page includes a Table of Contents for quick navigation:

  • •Desktop: a fixed sidebar on the left with clickable links to each rule, organised by category.
  • •Mobile: a collapsible "Quick Navigation" card at the top of the page.

Clicking a link scrolls smoothly to that rule. A Back to Top button is always available in the bottom‑right corner.

Searching & Filtering

  • Search: text search across rule titles and content.
  • Category filter: button bar with "All Categories" plus every category used in the campaign. Click a category to show only rules in that group.

Editing & Deleting Rules

GM only
  • Edit: update the title, category, content, or order of any rule.
  • Delete: permanently remove a rule. This cannot be undone.

Players can read all rules but cannot create, edit, or delete them.

Example Workflow

Here's how the Rules page might look in a typical campaign:

  1. 1The GM creates a "General" category and adds a rule titled "Session Zero Agreements" with the party's social contract in Markdown.
  2. 2A "Combat" category is added with rules for flanking, critical hits, and houserules around death saves.
  3. 3A player mid-session asks about the flanking rule. They open the Rules tab, search "flanking", and scroll straight to it.
  4. 4Between sessions the GM updates the death save rule to reflect a change the party agreed on.
