There was no need to bandage or use a pot for me during the fight. We killed it and the one just breaking out of the trap. The pet immediately attacked the voidwalker on me and I wing clipped it and ran to range. The voidwalkers do very little damage so I ingnored the remaining one until the succubus was dead. The succubus was at half health and so was my pet so I focused fire on her as 1 of the voidwalkers hit the freeze trap. I poured everything I had onto the boss and killed him as he summoned 2 voidwalkers. I laid a freeze trap at my feet, hunter's mark on the boss, and sent my pet onto the Succubus next to the boss. Now you are faced with just the boss warlock and the succubus. Wait until each one paths as far from the boss and just range pull each one back near the top of the path you just came up. In front of him on each side is a felhound (fellslayer is the name I think). Go to the top of the path and look at the camp area where you will find the boss in the middle and his succubus next to him. He is not linked to anything and you can pull him down the path safely. Once you start up the short hill path, there is a felguard at the top. I just used a freeze trap on the pairs with my pet on passive and pulling both to me and freezing one. The patrols are singles with an occasional felhound and felguard pair. You can come in either end of this but the path up the hill to him is at the bottom of the "U". The area to get to him is shaped like a "U". The area to get to him is mostly level 22 - 24 demons. Comment by CatalyzeI just did this quest as a 22 Hunter.
