Discord Bot Guide

Our Discord bot supports the exact same systems, rules, calculations, and visual styles as the web app!

1. Pre-Selecting a System (Session Mode)

Instead of entering the game system for every single roll, you can set the channel default system using the `/system` command. This sets it once for the entire session!

/system name: Call of Cthulhu (Percentile)

Once set, every subsequent roll in that channel will automatically use that system's math, show its theme accent colors, and embed its logo image. To check the system, look at the top/bottom of the roll embeds.

2. The Roll Command

Use `/roll` (or shorthand `/r`) to perform rolls.

/roll dice: <expression> [system: <system>] [modifier: <modifier>] [mode: <mode>] [skill: <skill>] [wild: <wild>] [hunger: <hunger>] [difficulty: <difficulty>]

Parameters:
