Malachite
The bright green of the malachite mineral has lost no vibrancy from being ground into a powder. Minuscule specks of lighter shades are dotted throughout, adding to the multi-hued effect and the light dust shifts slightly in any breeze.
Pinches of ground Malachite are alchemical minerals, which can be stored in the rift. Administered by smoking, it creates anti-weapon field that lasts until taken down by others or you act aggressively. Causes weapons attacks to rebound.
