Tarnian Necrotoxin
Description
Tarnian Necrotoxin is not made, it is a fluid secreted by a race of vile lizard humanoids, both powerful and infused with dark magics. This black ichor is thick and volatile, destroying any flesh it comes in contact with at a rapid rate. This toxin is the primary reason Tarnian Lizards are feared by all who encounter them, although their substantial strength and ferocity could be enough by itself. Gathering the Toxin is extremely difficult, for if even a tiny drop touches flesh, it could potentially tear through even the most resilient hero.
Lore
The Tarnian Lizards are a race of unknowns who have existed on the material plane for a very long time. They are rumored to serve the chaotic will of a massive god-thing version of themselves, although this beast has never been encountered. This is fortunate, for the result could very well mean the end of the goodly races of the surface. History is filled with accounts of people dying horribly on Tarnian Necrotoxin infused claws, their flesh rent to pieces while the nightmarish fluid seeps from their wounds, melting them to nothingness. A few have attempted to harness this fluid and weaponize it, but such attempts backfire due to underestimating the potency of the fluid, eventually claiming anyone who tries to use it.
