Might add that a Good place to pick up added chaos features is Sorcerer of Pan Tang. They have a few pages devoted to Demon features that are fun to play with. I gave a Broo a sling and a couple of eye stalks in the Big Rubble and did he play havoc with the party.
And of course there always making up your own when you get an evil thought. My favorite was my flamethrower Broo. I think most of us know the Human body makes flammable methane gas and how the human body expels it. So I thought how is the simplest way a body would make and throw flame. My players first was wondering why the Broo ran up to them turned around , grabbed his knees and mooned them. And of course then it hit them. For 3d6 fire damage.
Maybe we could make a list of our favorite chaos features we have come up with.
