Steam

Steam is the resource used by the Tinker metaclass. It was introduced as part of the Embers of Rage DLC. Fatigue plays no role in determining steam costs.

Steam is generated by steam generator injectors, which generate a constant amount of steam per turn. Steam is consumed by steam-powered weapons when used in melee or ranged fire, by steam-using talents, and by steam-using sustains. Unlike some other resources, most steam-using sustains drain a fixed amount of steam per turn.
