Hi!
I’m a Amatuer Historian, specialising in 13th & 15th C.
For war, archers did indeed use Belt Quivers, as you need to be able to hold a vast amount of arrows (from 24 to around 35, depends on how rich & generous the commander is). You had the at the waist for a variety of reasons, Quick reload, drawing an arrow from quiver, to bow from the belt is a very quick, swift and dare say elegant movement; much quicker than drawing from your back. An arrow is very long, and it’s easier on your muscles (More natural) and quicker to draw something so long (About 28" arrows for myself,) I’ve tried drawing an arrow from the back, to my dismay and getting muddled up during the action, even after a few attempts its still very slow (Sort of like the whole big sword on your back).
And as for hunting, you don’t need many arrows, 12 at the best, and why bring a quiver at all? That’s just more money you need to spend, a hunter wouldn’t be rolling in money, and it’s just as easy to put a few arrows in your belt (Which you can’t do with 24 obviously, that’d just be awkward hene a quiver is used). When I go and loose a few arrows off, I normally take a quiver down full of arrows and then put about… 5 - 10 in my belt My quiver acting as a arrow bag).
As for a bowyer minigame, I disapprove of games that let people craft too many items, it seems to OP and less lore friendly, if you’re a blacksmith, sure ake armour and weapons from iron rods, but don’t go and carve out a bow as that’s just silly without the full training and knowledge (Not to mention time involved in learning).
Anyhow it’s late at night and I’m tired so I’ve probably missed things out, any questions just ask (Pm me to guarantee a response)
EDIT: looked back, and edited to the correct amount they’d be issued on average (But you can still fit 60 arrows in a basic quiver, not much for anything else tho )
