[An Enemy Spy]

Really? I thought the one billion sided die was a common enough one that Byron Hall wouldn't need additional formulae.

I have yet to encounter a billion sided die roll yet, but I can confirm there a table that requires you to roll a ten million sided die. One a table that only has five outcomes. It's to see how many kids you give birth to after you presumably get accidentally raped by a troll because you unwittingly drank a philter of Troll Lust.
