Boil an Anthill

From Munchkin Wiki

A Go Up A Level card. Inspired by the idea of some Dungeons & Dragons players that "if the least amount of XP I can get from killing something is 1, how about I go out and boil an anthill with millions of tiny creatures that all give at least 1 XP? Surely, it will give me a million or more of instant XP!" This is usually not very popular with the GM.
