The Ebon Shrike is a spirit from the abyss summoned by a priest of The unholy Trio for 1 year (through a blood offering ritual). It is always in pain, always vicious and angry. It looks like a disheveled crow, and loses feathers whenever it alights, only to grow them back in a moment with blood oozing from the creature. It is silent and deadly. It can detect familiars in 80m radius, or anything acting like one (with a link to a master). It does not communicate except in a low raspy, coughing voice that sounds like its choking on blood and sand.

When it kills a familiar, its bound master is targeted with a False Life spell for 5hp.
When the creature dies, it explodes and scatters its blood in a 5′ radius, doing 2d6/7 necrotic damage.
