[Ultraviolet]

Back in our long running 3rd ed Cliffhanger campaign several characters had one or more of Overconfidence and Impulsiveness.

The German nobleman turned foreign legionaire and the Texan stuntman both had Overconfidence and at least one had Impulsiveness

My own character, an Australien archeologist/tough guy had Overconfidence and Jealousy. So whenever one of the others did something impulsive and overfonfident, he was sure he could do it better.

One time, on an arctic adventure, a polar bear was stealing our food from camp. My character was goaded into walking over and taking the food from the jaws of the bear. Needless to say, a fight broke out.

And one time, the group was eacaping from a giant air craft carrier zeppelin. They doused the entire hangar with aviation fuel and prrachuted out. Except the Texan stuntman waited behind, until he saw the fire had really, really lit up. He didn't have to jump, he was thrown.
