it would be nice to have replenish-able healing item upon resections, farming for food during boss run is very discouraging, ended up beating the boss with no food on hand. or maybe consider having herb regenerating on the check-point every time player resurrect.
Also having the inventory slot to bind with boss drop seems unnecessary, inventory slots should just be craft bigger bags to increase, instead of using rear boss item, which intuitively speaking should unlock permanent character peaks or skills.
one more quality of life change it that have locked door marked on map.
