A while ago when Discord I was in a D&D group that was playing over Discord, and we needed a good dice-roller to use in-chat. I wrote up this bot using the Discord API wrapper for Python so we could get pseudo-random results in-chat.

That D&D group is not meeting currently, but a couple of other groups have taken up using an instance of the bot named Pythia I keep running on Heroku. If you'd like to have her roll dice for your group, you can do so here.
