A trivection chamber can be installed in the Augmentation tab in a redstone furnace’s GUI. It is a specialization that cannot be installed together with other specialization augments.
A redstone furnace with a trivection chamber installed produces 1.5 times as much cooked food when processing raw food. The output amount is rounded down when necessary, but is always at least 2, which usually means that a single unit of raw food is processed into two units of cooked food.
However, a redstone furnace with a trivection chamber installed cannot process anything other than food, and the amount of energy required per operation is increased by 50%.
If a trivection chamber is installed together with other augments that increase the amount of energy required per operation, their energy increase percentages are added together before being applied to the amount of energy.
