Make a self-control roll when presented with a tempting morsel or good wine that, for some reason, you should resist. If you fail, you partake – regardless of the consequences.
You come unglued at the thought of reptiles, amphibians, and similar scaly slimies. A very large reptile, or a poisonous one, gives -2 to self-control rolls; a horde of reptiles (such as a snake pit) gives -4.
