How to unlock the Butterfly Effect achievement in Remnant: From the Ashes - Definitive Guide

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.

Why do those two Ixillis drop just one heart? This whole quest makes no sense! >_<

Tough boss because there’s actually two of them and many of the attacks can knock you off the bridge where you die and team mates can’t heal you. Weak point is the centre of their faces. Loads of ammo spawns in the centre of the bridge so remember to grab some as you run by.

As you enter the boss room only one will be visible on the left. The second one will be inside a cocoon high on the right. You can wait for it to spawn but, if you damage the cocoon first, you can force it out and on lower health. Then it will back off to charge up the beam attack and you can focus on the one already out. Would recommend someone with long range keeping an eye out for them coming back and shooting them in between.

When they are close to the bridge they do a regular damaging line slash and cone slash. Timing the dodge roll is essential because they hit hard. They also throw bombs you need to dodge that leave clouds of corruption behind. You can buy green leaf to neutralise this from the butterfly queen.

The closest one will then summon a load of homing orbs that also hurt a lot. Dodging is tough and you can destroy the orbs with one shot from a side arm. Distraction mods don’t seem to work on these either. We found it easiest to just shoot the orbs.

When this happens it indicates the other boss will be coming back with the beam attack so hopefully someone will have kept an eye and can warn the others. The beam does big damage and knocks you back so can push you off the bridge. It fires 4 beams in a row going from their left to right (or your right to left if facing them). So wait for the beam to fire first and then run into the area it just hit to avoid it. The other one will still be attacking so still watch out for that scythe and those bombs.

Afterwards they both start charging a scream attack. The only way to avoid this is to hit them hard and stun them out of it. They also become vulnerable in this state so it’s the best time to do big damage. The screams can kill everyone if both attacks hit so focus fire on one and then the other just in case you can’t get them both down.

After this they switch sides so the one you were close to will back off to charge his beam. The pattern repeats like this until one dies. Whichever one is left will be able to fire the beam attack now and this appears to be random instead of the previous predictable pattern. Hopefully the remaining boss will have low health enough that you can make quick work of them though.

There is a separate trophy for giving the heart from this beast to the Undying King by the way so remember that afterwards.

Good luck.

Story related, cannot be missed.

Ixillis XV is the world boss of Corsus and will prove you with the Swamp Guardian's Heart to give to either the Iskal Queen or the Undying King. Defeat it for this achievement.

One of the bosses of the Yaesha location.

The boss drops 2 types of loot:
  • Ingredient for creating the "Swarm Cannon" pistol
  • Ingredient for creating the ax "Guardian Axe"
For the pistol you just need to kill 2 butterflies.

For the ax you need both butterflies to die AT THE SAME TIME.

It is important to remember that only 1 ingredient drops, depending on how you kill the boss.

Firstly, the boss of Ixillis XV is located in the world of Corsus, not Yaesha
Secondly, for an alternative kill, the second butterfly must be killed before it goes into a rage (Before it stops screaming after the death of the first butterfly).

For secret loot in solo, it is enough to lower the HP of two bosses to 15% and wait until they start preparing a joint attack with a scream (the long animation of preparing a scream prevents the remaining boss from launching aggro and gives time to finish him off)
