Well only advice I can think of is this:
put in "isweapon" flags in all stuff which it only needs to if it is a weapon, put a !isweapon flag in any things which it needs to do if it isn't a weapon, use strings for storing how many stamina the player has, and make sure that it doesn't reset the stamina everytime the player entesr another level.
