Dungeons & Data

Dungeons and Data is a D&D 5.5e-compatible client (kinda like D&D Beyond) for Windows and Linux. (macOS support will be added later.)

System Requirements

Windows

• OS: Windows 7 SP1 or newer
• Python: Only Python 3.8 has been tested, but whatever supports the json5 module, I suppose

Spellsets

I'm writing spellsets in alphabetical order. That means that Warlock and Wizard are last, and Bard and Cleric are first. The current spellset I'm doing is the Druid level 1 spells.

How to format your own Spellsets

An example:

{
  name: "Sorcerer Cantrips (SRD)",
  date_added: "September 3rd, 2026",
  last_updated: "September 4th, 2026",
  source: "System Reference Document v5.2.1",
  author: "Dungeons & Data authors",

  spells: {
    sorcerer_acid_splash_0: {
      name: "Acid Splash",
      id: "sorcerer_acid_splash_0",
      level: 0,
      school: "evocation",
      concentration: false,
      casting_time: "1 action",
      range: [60, "ft"],
      components: ["V", "S"],
      duration: [0, "seconds"],
      desc: "Spell description.",

      cantrip_upgrade: "Describe how the spell improves at higher levels."
    }
  }
}

Spell fields:

• name: Display name.
• id: Unique spell identifier.
• level: Spell level; use 0 for cantrips.
• school: Magic school, such as "evocation".
• concentration: Whether concentration is required.
• casting_time: A string or [amount, unit] pair.
• range: A string or [amount, unit] pair.
• components: Array containing "V", "S", and/or "M".
• material_desc: Material component description when "M" is included.
• duration: A [amount, unit] pair when applicable.
• desc: Spell description.
• cantrip_upgrade: Optional cantrip scaling description.
• effects: Optional object for spells with multiple selectable effects.

Use JSON5 syntax, which permits unquoted property names, comments, trailing commas, and multiline strings.

To-do list

• Spellset creator inside of the game
• Actual, functional client
• Spellset viewer
• Complete "weaponsets" and "monstersets", as well as "itemsets"
• GUI version
• 3e/3.5e + 5e support (more JSON5, yippee)
