Untameable look : This look is not known from a tameable creature.
Required Skill: Blood Beast Taming
You must learn a special skill to tame Blood Beasts. It is taught by a Blood-Soaked Tome of Dark Whispers, a guaranteed drop from Zul in the Uldir raid on Normal Mode or above (i.e. not LFR). Once learned, this skill is account-wide.
This creature can only appear if Nerubians are invading Skittering Hollow in Island Expeditions that week. These two variables change weekly and are shown when you click on the table before entering.
Can spawn during a periodic area event in which the Nerubians launch an attack against Warsong Hold.
Level scaling: Most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
