Acidborne

Acidborne is a Plague subspecies created by  WendigoPsychosisAcidborne are not skinless in the traditional sense; they are the adapted survivors of a catastrophic event. Some speculate early derivatives may have fallen into the Wyrmwound but managed to survive, at great cost. Others believe a wayward Cystic bestowed its "gift" upon them. What is fact is that they produce an acidic substance which eats away at their skin. This prevents the outer flesh from ever healing, but grants them a dangerous weapon against any who dare to get close.

Lore
This subspecies does best in its natural plague environment, though it may be possible for them to thrive in nature. Their secretions burn anything that comes in contact with it, which subsequently manifests as agonizing sores paired with unavoidable infection. (It's wyrmwound stuff, what did you expect?) Leprosy, pustular psoriasis and erupting acne are often associated with it.
