Hello, Archers are pretty bad at grinding for a long time. There was something put in place to make it a bit easier, infinite quivers. Maybe for B grade don't put them in, because you cant buy arrows, or put them in as hard craft. It's really hard to go +12 str -15 con on an elf archer when he can only carry maybe 500 arrows + soulshots if his con is this low https://l2wiki.com/Infinite_Steel_Quiver
