Attach (Ex): If a skulking cyst hits with an intestine, it latches onto the opponent's body. An attached skulking cyst has an AC of 15.
Blood Drain (Ex): A skulking cyst drains blood, dealing 1d4 points of Constitution damage in each round it remains attached. Once it has drained 7 points of Constitution, it uses its necrotic cyst ability. After that, it drops off and attempts to skitter away into a shadowed corner or other hidden location.
Inescapable Craving: A skulking cyst has an inescapable craving for blood, which it satisfies by using its blood drain ability.
Spell-Like Abilities: 3/day - darkness; 1/day - necrotic cyst. Caster level 3rd.
Skills: A skulking cyst has a +8 racial bonus on Hide and Move Silently (already calculated into the statistics above).
A creature of shadows, a skulking cyst prefers to launch attacks on lone victims from dark ceilings and sewer grates.
A skulking cyst is disgorged from the rotting corpse of a living creature, born of a necrotic cyst that eventually kills its host (see the necrotic cyst spell,).
A skulking cyst prefers shadows and dark corners, only revealing the horror of its form when it strikes lone victims from hiding. Though often cloaked in the detritus of a previous victim, the skulking cyst's true "heart" is a 1-foot-diameter spherical sac that contains fluid and semisolid necrotic flesh, which slowly undulates as if in a mockery of breath.
A skulking cyst does not speak, but it understands Common and the languages its fleshy carapace originally spoke in life.
