At the start of each of the bleeding gasper's turns, the target loses 7 (2d4 + 2) hit points due to blood loss.
Projectile Bleeding. Ranged Weapon Attack: +4 to hit, range 10/20 ft., one target. Hit: Target is blinded for 1 minute.
The bleeding gasper perfectly resembles a large, plump leech at rest; however, when a creature draws near, sucker-lined flatworms spring out and attack. Sometimes known as a "Bleeder" for its tendency to spray pungent, bitter, sticky blood from its suckers and minute pores in its skin when threatened, this creature is a true ambush predator; it anchors itself in an underwater location, and will spend days or weeks motionless as it waits for suitable prey to wander close enough. In battle, the bleeding gasper tends to favor underhanded tactics, attacking while hidden behind cover and using only one of its two flatworms, reserving the second for a surprise strike when its adversary is at their most distracted.
