Consumables are items that can be consumed or equipped by players to increase players' stats.
When consumed, their effects are permanent. However, each time the player used a consumable, its effect will start to diminish until it may not raise stats again. This effect is permanent per consumable per player per playthrough. The starting value on how much the consumable will raise a player's stats can be seen on the table. After each use, it will start to lose its effect till it gives either a 0 or 1 result in stat increase (this means that the consumables has reached its max uses becomes ineffective). The minimum stat value is 1/5 of the initial value rounded down (consumables that start 1-4 can be 0-1, 5-9 are 1, 10+ is 2).
When equipped, consumables will increase players' stats with the values listed in the table below.
Note : Supplement consumables increase 4 stats when equipped. However it will only raise 3 stats when consumed (it will not give increase in tech stat). This is marked on the table using bold and italic.
