Grim Shriek. If a shadow beast dies within 30 feet of the shadow beast, it can use a reaction to let out a loud shriek and restore the shadow beast to life with 5 hit points. Each time a shadow beast is restored to life in this way before it completes a long rest, it regains 1 fewer hit point. It can't be restored if this would cause it to have 0 hit points.
Grim Curse. A humanoid slain by a shadow beast rises 1 hour later as a shadow beast, unless the humanoid is restored to life or its body is destroyed.
Strike. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) necrotic damage.

Twisted beings under the thumb of the usurper king Zant or just warped via Twili magic, one thing remains the same: shadow beasts are mindless, wandering engines of destruction. If left alone, shadow beasts will wander aimlessly around, however when they detect a sentient creature they will viciously attack it until it is killed and turned into one of them. Usually attacking in packs, one single shadow beast can quickly become a major problem if their slaughter gets out of hand, as an army of shadow beasts is nearly unstoppable.
