Phantasm

Phantasms are wispy, nearly invisible ghosts. They are the third most common Type Twos, and are equal in power and behavior to Specters and Wraiths. They're best dealt with using iron chains and lavender, what with Phantasms being nearly impossible to see, salt bombs and rapiers aren't very effective. Despite having transparent plasm, they can ghost-touch just like any Specter, and are more dangerous then these for being harder to see. Lockwood and Co. encounter a Phantasm just outside of the Lavender Lodge Hotel, and Anthony Lockwood is attacked by two at the same time at a church where twin brothers were murdered. The word Phantasm likely originates from the word phantom, and what Phantasms are made of: ectoplasm.
