Light Crossbows

The Light Crossbow is a very simple weapon and can be used by any class that does not have a restriction on missile weapons or drawing blood (clerics.)  It DOES NOT require a weapon proficiency to use!  It only requires instruction from anyone already able to use one and about an hours practice.  Shooting without that practice will cause penalties to hit until the character spends an hour practicing.
An hour’s practice is equal to 30 shots with the crossbow.  The first 10 are at -3  The second 10 at -2  The third 10 at -1.  Thereafter shots are made with no penalty.  If a character picks up a lighr crossbow and begins using it without the training, the same penalties and count will apply until the character has used it 30 times.
