Reservoir

A reservoir is an item that stores fluids. It is functionally similar to a bucket. It can also automatically refill a player’s equipment.

Usage

Fluid storage

A reservoir can be filled and drained by hand, or automatically using a fluid transposer or similar. It can be filled and drained at rates up to 1,000 mB/t. A basic reservoir can store up to 10 buckets worth of fluid (10,000 mB). This can be increased by upgrading the reservoir to a higher tier.

A reservoir can be in one of two usage modes: Fill and Empty. The current usage mode of a reservoir can be switched by pressing “Cycle Item Mode” (V by default) while holding it.

When a reservoir in Fill mode is used on a fluid source block, it picks the fluid up like a bucket and stores it. When used in Empty mode, a filled reservoir places one bucket worth of fluid in the world.

A reservoir can also be used on blocks that store fluids to fill or drain them.

Refilling items

A reservoir can be activated and deactivated by using it while sneaking. When active in a player’s inventory, a reservoir automatically refills held and worn items that can hold fluids.

If Baubles is installed, reservoirs can be equipped as baubles in any slot.

Dyeing

A reservoir can be dyed by combining it with a dye in a crafting grid. The dye can be removed by placing the reservoir in a crafting grid.

Enchantments

A reservoir can be enchanted with Holding to increase its capacity.

Tiers

Reservoirs come in six tiers.
