How many arrows can each quiver hold?
and if the amount is set, how do I go about doing that?
Also, I can't select my arrows on the inventory in game, yet the selector on the Subscreen editor I can...
Quivers?
You need a Bow before you can use Arrows in-game.
Secondly, you change the Quivers' "Increase Amount" in the Item Editor.
Thanks!
