DiscordDiceBot VS DiceMaiden

You can use my bot https://github.com/twonirwana/DiscordDiceBot to roll d100. If you want use a d100 use /custom_dice start buttons:1d100 to create a message with a button that rolls the d100 every time you click on it.

My dice bot can create custom dice, see https://github.com/twonirwana/DiscordDiceBot . With numbers it is easy (e.g /r expression: d[1/2/2/8/10]). A mapping of dice results number to text/Unicode icons is also possible but a little more complex (e.g 1d6<=2?Blue<=4?Red:Black). The best is you can create buttons for the dice expression and all user can roll by clicking on buttons, without knowing the dice syntax.

If you're still looking for a dice bot, I'd recommend Dice Maiden. I know a lot of dice bots for Discord have disappeared in recent years. Also, I'd recommend only giving the bot access to channels it needs to listen for rolls in (I have a DM-only channel exclusively for behind-the-screen rolls), just in case anyone figures out how to abuse it to read priviliged channels.

I run games on Discord all the time! You can use a dice bot like Dice Maiden or RPbot.
