Drain Deimos has an HP value of 74-130 on HEAVY mode, and 47-86 on LIGHT mode. They can scale walls and attack by slashing at or grabbing and biting their prey. Although not as fast as some enemies, this monster can rise up on its rear legs and 'run' at the player. If the player cannot escape, it will grab the character and plunge its jaw into their skull in order to extract the cerebra-spinal fluid, which seems to be a favored food. The Deimos can also use its powerful back legs to leap around its preferred hunting grounds, in order to close the distance between itself and the player or to prevent an escape. These monsters prefer places that are dark and damp, frequently lurking in back alleys and old buildings.
