Malicious ghost of a vengeful snake. It has the ability to make people fall asleep. The victims are strung up in front of their houses with their heads turned inside out.
Will usually appear alone or in 2's. They have high HP and can cause the Affliction Petrify which can be annoying, so have a Crucifix equipped or a Zodiac Bracelet equipped to negate that. They also have a high attack so take them out quickly.
An Asp is an archaic term for any poisonous snake especially the Egyptian Cobra.
