Booster Tank

The Booster Tank is a special oxygen tank with the ability to trade oxygen for a speed boost. It has the same capacity as the High Capacity O₂ Tank at 90 units, for a total of 135 when it is equipped. Equipping one also incurs the same movement penalty of 0.47 m/s underwater and 0.61 m/s on the surface.

Usage
The Booster Tank is equipped in the paperdoll UI's oxygen tank slot. The player can press to boost swimming speed by more than double, at the cost of an additional five units of oxygen per second. The Booster Tank only works off the Oxygen actually in the tank, and cannot be activated using the final 45 units which represent Robin Ayou's lung capacity. It can be used without limitation at the water's surface, making it a very fast way of travelling.

Recipe
The blueprint for this item is acquired from a Data Box found in Purple Vents, located in a narrow trench below the area where the Chelicerate patrols. It is crafted with the Modification Station.
