Non Groups

The following weapons do not belong in any sort of group whatsoever. To learn any of these weapons, the character must spend a weapon proficiency slot on it, and none of these is similar in use to any other weapon. When a character picks one up and uses it without being proficient in it already, he suffers the full penalty.
Any weapon marked with an asterisk ( * ) is a weapon described in The Complete Fighter's Handbook, in the Equipment chapter.
