Chaotic Dreams

I think the creeper runes (from an Unreal and old Q 1 mod that had a large library of "relics" that intertwiend witheachother for that tasty element of strategy+luck) would fit in very well with chaos. for more info on this check http://www.captured.com/creeper or http://www.planetunreal.com/realCTF/RealCreeper. it was/is a lot of fun (people still paly the original Q1 game =) ) so its worth a look.
