Wyrm's venom is the toxin contained in the venom of a wyrm or darkling crawler. The venom is a toxin with psychic as well as physical effects. Among the physical traits of wyrm's venom are a distinctive taste and aroma which Jame has learned to recognize after having been poisoned, as well as the venom's corrosive nature. The latter trait is shared with several other toxic fluids on Rathillian, even those not of darkling origin.
