In Solasta, backpacks are worn items, and magical versions, in the vein of bags of holding exist- reducing weight by a certain %.
Cant care less about what they do in some completely different game. :-/
They don't seem interested in giving us the old school BG2 scroll cases, potion cases, quivers and bags of holding that brought some level of organization to inventories.
Hey they need to keep something for moders comunity aswell.
