Compendium
Open Compendium in the campaign sidebar to look up the rules: spells, monsters, magic items, equipment, classes, subclasses, species, backgrounds, feats, class features, species traits and conditions.
First use
Section titled “First use”The compendium shows the rules sources the DM turned on for this campaign. Beholder downloads each source once, the first time you’re online after it’s turned on (the SRD is about 200 KB, a book between 5 and 220 KB). After that, the compendium works offline and opens instantly. When the server gets an updated version, Beholder downloads it again on its own.
Sources
Section titled “Sources”Besides the SRD 5.2, the server offers open-licensed books from the Open5e project, which the DM can turn on per campaign under Settings → Rules sources:
- Kobold Press: Tome of Beasts 1 (2023 edition), 2 and 3, Creature Codex, Deep Magic and Deep Magic Extended, Vault of Magic, Tome of Heroes, Warlock Zine, and a compilation.
- Kobold Press, Black Flag SRD.
- EN Publishing, Level Up (A5E): Adventurer’s Guide, Monstrous Menagerie, Dungeon Delver’s Guide, Gate Pass Gazette. Level Up uses different rules from standard 5e.
- Wizards of the Coast, SRD 5.1 (the 2014 rules).
- Smaller sets: Tal’dorei Campaign Setting, Spells That Don’t Suck, Open5e Originals.
Every entry shows its source and rules version (2024, 2014 or Level Up).
Searching
Section titled “Searching”Type in the search field: results update as you type, and names that start with your words come first. You can type part of a word (fireb finds Fireball), and search also looks inside the rules text (prone finds everything that knocks a creature prone).
Pick a Type to narrow the list. Each type adds its own filters:
| Type | Filters |
|---|---|
| Spells | Level (or cantrips), school, class |
| Monsters | Challenge rating from / to |
| Magic items | Rarity |
| Class features, subclasses | Class |
Click a result to read the full entry: spell details, the complete monster stat block, a class’s level table and features, and so on.
Same name in several sources
Section titled “Same name in several sources”When several turned-on sources have an entry with the same name (Fireball is in both SRDs), the list shows it once, from the source with the highest priority: your server’s own entries first, then the SRD 5.2, then 2024, 2014 and Level Up sources. A +1 version label marks it, and the entry’s page lists the others under Also in: click one to read it.
Content and credits
Section titled “Content and credits”The compendium contains the System Reference Document 5.2.1 (the 2024 core rules) and the open-licensed books above, under the Open Game License 1.0a, Creative Commons Attribution 4.0 or CC0. Content from books you own will come later, as entries your group adds to its own server, never bundled with the app.
