(If you are wondering why I dont use Predatory bond Its because it's not usefull in this solo because u only have to kill one person. If you dont feel comfertable without it, take out one of the attack skills)
Basically you exit leviathan and head towards reefclaw. I get a blessing from the luxon priest outside cause it helps in a few spots. When you come to the boss you will notice that he is surround by six rotwollow. You can either take one group of the rotwollow or just get the patroling outcasts to kill them for you. If you use the outcasts, head towards the southwest side of the boss.
Try to aggro all the rotwollow to the outcast so that they will fight.
Once the rotwollow are dead head to the side closet to leviathan pits. When fighting the boss. Make sure that he DOES NOT get off Preservation. Bring either distracting shot or disrupting lunge(which ever you prefer). I use distracting shot cause my pet is slow -_-. Just spam all your attacks on him. heal you pet with comfort animal when he uses his dmg spells and he will die. Only killed him twice so far, no drops

Hope this helps to anyone wanting that green.

UPDATE: I got one
