Pewter drag

A discipline Mistborn and Thugs use to push past the limits of the body — flaring pewter continuously to keep the physical reserve burning while the body is run beyond its real endurance. A Misting on pewter drag can keep at near-peak output for hours; the body still pays, but the bill arrives the moment the metal runs out, all at once. Letting the metal lapse before stopping is dangerous; the fatigue can drop a runner straight into unconsciousness. MB1:TFE:Ch 25
