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.
You can never learn to use magic, and you react badly to any user of magic. Make a self-control roll whenever you are in the presence of magic. This roll is at -3 if you are to be the target of friendly magic, and -6 if you are the target of hostile magic. (The magic does not have to be real, if you believe in it!)
