Special Skill Required : To learn how to tame Blood Beasts, you must obtain a Blood-Soaked Tome of Dark Whispers. This book is a guaranteed drop from Zul in the Uldir raid on Normal Mode or above (i.e. not LFR). Once you learn the tome on one hunter you can tame Blood Beasts with any hunter on your account.
**Creatures in Zandalar (Zuldazar, Nazmir, Vol'dun) do not scale for Alliance hunters, and creatures in Kul Tiras (Tiragarde Sound, Drustvar, Stormsong Valley) do not scale for Horde hunters, except in defined war campaign areas. Outside these areas they will always appear level 120 but can be tamed when the hunter is level 118.*If a creature's level is noted as 'Scales' then it will vary with the Hunter's level within the constraints of its level range.
