In this video guide I will show you how to defeat Ixillis XV. The Undying King will give you a quest to retrieve a heart for him. It will take some time until you get to this boss. You will first talk to the Swamp Queen before reaching this boss.
This boss has quite a bit of moves and is a real pain. He will throw bombs
at you for starters. Then one you get his health down a bit he will cast some spirits
at you. Be careful because they will come from behind you as well.
Once you get his first section of his health he will have a second one show up
. Make sure to get head shots to be able to stop the charge up blast
or you might die. Keep focusing on the first one as much as you can since its health should be lower.
At this point the first one will fire a beam
starting at the far end of the bridge. Just try and keep an eye on both of them if you can. Try to time the blasts when he stops and get to the other side. They will both be attacking nonstop. This part gets hard until the first one dies.
They will both be using the spirits from both sides so take them out first when you see them. They also have a few striking attacks
as well so be prepared for those. Other than that it will be a repeat of the same attacks. Just be sure to kill the first one first
to make killing the second one easier. Once you kill them both the achievement will pop.
