What is this i don't even
Try dealing with arrow upkeep and maybe you will figure it out. You don't want to load arrows you wont use. Since you likely won't use much more than a quiver (and maybe less than 1) on some maps, it doesnt make sense to load two 800 gold penalty bodkins that you wont use. Get some 148 gold barbed instead for the second quiver. However, if the system uses the barbed first, there is no point in loading bodkins at all, or you need to switch them around so that the more damaging arrows get used first.
That's why it is important to know which are being used first.
