Aluqa

An ancient vampiric demon from Hasidic lore,the aluqa looks like a beautiful woman with a face suggesting nothing but pure innocence. However, despite this demon's beauty, a snake lives coiled around its heart. Typically it attacks men as if it were a SUCCUBUS, but it can also cause madness in its prey. Its victims oftentimes are made to feel the full weight of their shame for having been seduced by such a creature and they will commit suicide. The aluqa is indestructible but can easily be driven off with prayers. Sleeping with an iron nail under one's pillow will offer protection from its attacks while sleeping.
