Pal Spheres
The number one thing people lose to bulk storage. Exclude every sphere tier you actually throw so a capture run never starts empty. Our /pals database lists which Pals need the higher tiers.
Ammo and arrows
Bullets and arrows sit in the same chests as your crafting stock, so they vanish quickly. Exclude the ammo for the weapons you carry.
Food and medicine
Cooked meals and medicine are the difference between finishing a boss fight and walking back from a respawn. Keep a stack excluded at all times.
Gold coins
Coins usually live in a chest already, which means bulk storage will happily take them. Exclude them if you buy from merchants while out exploring.
Quest and craft materials
If you are hauling something rare to a specific bench, exclude it until the craft is done, then take it off the list.
