I have a simple suggestion to make pocket dumpling AND the associated character stat that has a chance of not consuming an item 10x more useful.
Current: Pocket dumpling uses a random consumable at the start of battle.
Suggested: Pocket dumpling uses whichever consumable you last used manually at the start of battle. If none are available, resets and uses a random item instead.
With the change, a “back to random” activation on the pocket dumpling item would probably be good.
