the javelin rules say specifically
"1.4.7.1. Must also pass as a Class 3 Weapon."
nowhere in the javelin rules does it say it must be only a class 3, does this mean that you could make a completely padded omni-glaive that was throwing legal as long as it is 16 ounces or less?
What if it conforms to staff rules which are blue and have no weight limit?
