Song: 少女幻葬 ～ Necro-Fantasy Simple Rock - Silver Forest

Somewhat tricky boss (Requires Engineering to solo without a some form of a pet). 30 seconds into the fight Jin'rokh will pick his current target up and throw them, if there are no other threat targets he resets. We use a Target Dummy or a Cardboard Assassin (A little harder to line up since it's placed at your feet) to temporarily gain aggro in order for Jin'rokh to leash us back to him (This causes your character to bug for a small time frame and you will not be able to act but you can still move). Afterwards you need to kill him before he can do the next throw. Standing in the water can help a lot when it comes to DPS/healing (40% increase) but will increase the Nature damage you take by 80% so be mindful.

Feint whenever Focused Lightning is about to hit you (Don't let it hit you in while in the water)

Bug: After he has thrown you and leashed you back to his melee range there is a chance that he will keep leashing you back to him whenever you move out of his melee range when trying to approach the water.

Not an Engineer? Grab a friend. (I'm told Jonn Dar's http://www.wowhead.com/item=86572/terracotta-fragment works, but I haven't tested it and you'll lose a trinket slot, plus it's a one hour CD)
