Elutriated Force is a Usable in Torment: Tides of Numenera.
Description[]
This crystal pulses with vibrant energy, softly expanding and contracting as if breathing in and out. A needle protrudes from the crystal's center... If inserted into a vein, the crystal's pulsing energy can be absorbed to increase the user's physical stamina and muscle mass for a short time.
These crystals are purified from a murky liquid found rarely in the Garravia Sound. Their origin is unknown, and the process to harvest them without destroying the active substance is difficult, but the supply appears plentiful.
