Filthy Tunic
A disgusting rag in desperate need of a wash and a type of body armor at the same time. It is made of hessian cloth with a very low strength modifier (lower than any other armor, even broken ones) with basic AV of 0. It can be hardened directly into angel hair though, but it will still have a very low armor value of only 3.
On the other hand, filthy tunic offers you a unique property of leprosy resistance. While wearing filthy tunic, you cannot be infected with leprosy neither from fighting nor ingesting zombies. Note that you have to wear the resistance does prevent infection but does not cure the leprosy itself - if you have already contracted leprosy, you will have to cure it by other means before the tunic can help you.
Can be found as a randomly spawned dungeon item.
