Cleanse a Felbound Wolf of internal corruption, allowing it to be tamed.
Fel Rangari Anaara drops a single Vial of Fel Cleansing when killed, which allows a player to turn a Felbound Wolf into a tameable Beast for one minute. these wolves can be found north of Vol'mar or at the Temple of Sha'naar.
Fel Rangari Anaara is a challenging solo fight intended for Hunters. Located directly south of Fang'rila in Tanaan. Non-hunters should not attack her, not even to help others, as she will use Deadly Shot against them.
She has a number of abilities specifically tailored for Hunters. keep moving during the fight, dispel Blessing of Fallen Kings(Damage dealt increased by 200%. Damage taken reduced by 50%), interrupted Tainted Light(Heals the caster to full health). So, be careful!
Make sure nobody is around before you try to use this, otherwise you may waste it and have to kill the boss again. because this item is one-time use only so be very careful and cautious especially if you are on a PVP server.
Maybe that will help you for tame lovely green fel wolf.
