Players in tournaments can bring Consumables, such as Potions and Smoke Bombs, into battles, with each Consumable assigned a weight in units of Stone.
The Battle Inventory represents the maximum amount of Consumables that can be brought into a battle, while the Battle Budget determines the amount of Consumables that can be used in a battle.
In tournaments, players designate their Battle Inventory, with the default being 60 Stone, and each match has a Battle Budget, with the default being 11 Stone.
This system provides flexibility and strategic decision-making for players, allowing them to manage their limited resources in real-time.
