RequiemBot 0.2.1

A simple tabletop RPG dice bot for Discord.

RequiemBot

This is a Discord bot for rolling dice (such as in tabletop RPGs) and optionally doing math on the results. Written in Python using discord.py.

Usage

Invite to your server:

I am currently testing the bot with a small group of people, and will make an invite link publicly available when I've received enough feedback.

Run locally:

(Requires Python ≥ 3.10. The GUILD_MEMBERS privileged intent is required for /stats to work properly.)

1. Install from PyPI using pip install requiembot
2. Set environment variable TOKEN to your Discord bot token
3. Run python -m requiembot

Details

Commands

• /help: Display a simple help message with examples and a link to this GitHub repo.
• /roll: Roll dice and/or do math, as described below. Options include:
  • secret: If set to "true", the result of your roll will only be visible to you.
  • repeat: Amount of times to roll the given input. Defaults to 1.
  • compact: If set to "true", the response will be shortened by removing the details of each roll.
• /stats: Display the number of Discord servers the bot is on, and the number of non-bot members across those servers.

Example Dice Rolls

• d20 ability check: 1d20 + 3 or simply d20+3
• D&D 5E attribute: 4d6k3 or 4d6d1 (or simply 4d6d)
• Advantage: 2d20k1
• Disadvantage: 2d20kl1
• Fudge/Fate: 4df
• Wild Die (Savage Worlds or Open D6): 1d6!

Details

• Dice are expressed in the form XdY where X and Y are positive integers representing die count and size.
  • X is optional; if it is not present, the default is 1
  • Y can instead be f to use Fudge/FATE dice which range from -1 to 1
• Dice can be followed by modifiers. These consist of a one- or two- character symbol, and optionally a positive integer X as described below (otherwise using the default listed):
  • dX: Drop the lowest X dice. (Defaults to 1.)
  • dhX: Drop the highest X dice. (Defaults to 1.)
  • kX: Keep the highest X dice, and drop the rest. (Defaults to 1.)
  • klX: Keep the lowest X dice, and drop the rest. (Defaults to 1.)
  • !X: "Exploding" dice; for every dice resulting in X or above, add another die of the same type, and repeat for every added die resulting in X or above. (Defaults to the highest possible value on the die.)
    • (To avoid infinite loops, this is capped at 10 repeats.)
• The following math features are supported:
  • addition +, subtraction -
  • multiplication *, division /
    • Note: The bot uses integer division. Results are rounded down and remainders are disregarded.
  • ( grouping )
• Whitespace (spaces etc.) is completely ignored between symbols. For example, (5d6kl3!k3dh1+2)*5 and ( 5 d 6 kl 3 ! k 3 dh 1 + 2) * 5 will be interpreted as exactly the same.

Planned Additions

(in no particular order)

• Count successes/failures, like World of Darkness
• Reroll on nat 1 (or some other number)
• Highest/lowest of multiple different expressions
• Proper code comments/documentation
• Unit tests
