Avrae Discord Bot

Avrae is a Discord bot designed to help you and your friends play D&D online.

You can join the Avrae Development Discord here, and invite Avrae to your own Discord server here!

Key Features

Advanced Dice Roller

With a custom dice parser, Avrae is one of the most advanced dice rollers on Discord, capable of supporting pretty much every type of roll needed to play D&D. Advantage, disadvantage, and crits are built in, you can keep, drop, or reroll dice as needed, dice can explode, and dice can be bounded.

Want to use the dice roller in your own code? Check out the code!

Character Sheet Integration

Avrae can read character sheets from D&D Beyond, Dicecloud, or a Google Sheet, automatically generating macros to roll attacks, ability checks, and saving throws. A player can then simply use a command to make a check, save, attack, or cast, and all necessary rolls will be resolved automatically.

Initiative Tracking

The initiative tracker is a fast way to track combat in a text channel. It supports automatic combatant sorting, HP, AC, resistance, and status effect tracking, and integration with the character sheet manager and 5e content to further streamline combat.

Moddability

Have a feature in mind that isn't already in Avrae? Avrae provides a fully-featured modding API to write your own commands, and a place to share them with the community!

How to run Avrae locally

Using Docker (Recommended)

Check out docker/readme.md.

Building Manually

OS Requirements

Avrae is built on Ubuntu, but should be fully compatible with any UNIX-based system. It is possible to run Avrae on Windows, but is not recommended.

Creating Support Files

You'll need to create a Google Drive Service Account. You can find instructions on how to do this here.

Follow steps 1-3 in the Signed Credentials portion. Rename the JSON avrae-google.json and put it in the project root.

Dependencies

Redis

You will need to run a Redis instance to serve as a high-performance cache. Download Redis and run a redis server locally before launching Avrae.

MongoDB

You will also need to run a MongoDB instance to serve as Avrae's database.

Python

Avrae requires Python >= 3.8.0.

Install the dependencies with pip install -r requirements.txt.

Environment Variables

These are the required/recommended environment variables for local dev.

• ENVIRONMENT - "development" for development
• TOKEN - a valid Discord bot token
• DISCORD_OWNER_USER_ID - your Discord user ID
• MONGO_URL - a MongoDB connection string (defaults to mongodb://localhost:27017)
• REDIS_URL - a Redis connection string (defaults to redis://redis:6379/0)
• NO_DICECLOUD - if set, disables dicecloud connection/importing, otherwise:
  • DICECLOUD_USER - a dicecloud username
  • DICECLOUD_PASS - the password for the dicecloud user
  • DICECLOUD_TOKEN - a dicecloud API token

Running

• If running Avrae in unsharded mode (recommended for testing), run python dbot.py test.
• If running Avrae in sharded mode, run python dbot.py.

Testing

To test Avrae, run these commands:

docker-compose -f docker-compose.ci.yml -p avrae build
docker-compose -f docker-compose.ci.yml -p avrae up -d
docker logs -f avrae_tests_1

This should initialize an ephemeral database to run command unit tests in. You should set the DICECLOUD_USER, DICECLOUD_PASS, DICECLOUD_TOKEN, and GOOGLE_SERVICE_ACCOUNT env vars to their correct values.
