Siegebreaker Diablo III Guide
Last update: 11 May 2016
Find the Demon Gate at the Edge of the Abyss
Head deeper into the Rakkis Crossing. This location is very similar in terms of its structure to the Bridge of Korsikk from the previous quest, however you'll be dealing with more demons than before.
At the end of the Rakkis Crossing you should be able to locate a passageway to the Edge of the Abyss.
Kill the Siegebreaker Assault Beast
The only way to move on is to defeat Kartan and you should know that this demon has a very extensive life bar. Fighting this monster in close combat may be very dangerous, because the boss can grab you with its huge claws and can then throw you, dealing severe damage. If you decide to attack it from a distance you also won't be completely safe, because the demon can charge at you. Thankfully the arena where you're fighting is large, so you'll always have a place where you can run away to.
Talk to Adria near the Demon Gate
As soon as you've eliminated Kartan you should notice that Adria has arrived here using a town portal spell. Talk to her to end this quest and to learn that Tyrael won't be a part of your team anymore.
