This week's mutation is hazardous Hellfire
There’s a lot of hype this week, and it’s only going to get bigger. The Dev Update video for Nighthaven was released overnight, Delos time, and it is huge! Stay tuned for a summary article or do yourself a favour and watch the whole thing (1 hour 22 mins). There’s so much coming, but something that’s important for mutation lovers to know is that M3s will be the only place to get 4 socket gear. So mutations are back baby! Get some practice in this week with three straight expeditions, and try not to get burnt!

Dodge Explosions
Explosive enemies go boom! Not only does this do a big chunk of damage but it also throws you around, even off the edge of the dungeon, if you’re close. Look for the title and be ready to dodge or get out of the way.
The floor is lava
The Burn zone from Enflamed enemies can get pretty hot, so make sure you’re stacking on, and staying in, the heals. Leaving and returning to this space may cause an (unintended?) double stack of burn, so either stay with the clump or stay out of the fire.
M2 - Melee and chunder
There’s a penalty for using ranged attacks once again, with Phalanx enemies putting up a deflecting shield, so make sure you have at least one melee weapon. Vampiric slows down the time to kill on mobs that have it, so slotting your Bile Bomb Heartrune can help.
M3 - To Ability or not to Ability
While Weary is (apparently) delayed by using abilities, they trigger Blood Offering. As long as you are doing damage, the life leech from Blood Offering should be enough to offset the Dot (if your Con is not too high, since it’s a percentage of max health). This curse is particularly challenging when swapping protection for a boss fight, since it still applies mutation type damage. If you’re hurting too much, consider sticking to basic light and heavy attacks rather than abilities.

Strategy and tips
There are lots of teleports, trigger platforms and azoth staff nodes in this expedition, as well as a plethora of ranged enemies. Use the twists and turns to your advantage by getting out of their line of sight and forcing them to come to you.
Main Damage Type: Void
The Archdeacon begins the fight in the centre of his arena, although he can move around if players do. He summons Corrupted dogs and has a nasty Ground Wave spell that you’ll need to dodge. Try to keep the dogs in the clump so they get killed by the hits on the Archdeacon.
When he gets to about 50% life, he’ll become invincible and channel a red beam to the east side of the arena. While the Archdeacon is invincible, mines will periodically spawn and if they are not destroyed they will explode and apply Void damage to everyone in the room. If you learn the timing, you can dodge this explosion. Two DPS should step on the teleport pad, which will take them up to a platform where two mages spawn. After killing the mages, one DPS needs to use their Azoth Staff on the node so they can both return to the main arena. Azamela will resume his normal state.
At about 20% health, the Archdeacon starts channelling again, this time with an additional green beam to the west side. You need to split the group and clear each platform as soon as you can. If the dogs are clear, the healer can remain on the ground and heal each side, but usually they will go up with the tank and DPS on the green side. Surviving the bomb damage at this point is the hardest part, clear quickly, dodge if you can, and use potions carefully to stay alive.
Main Damage Type: Fire
Thorpe has been with us since the first sea voyage to Aeternum, so we should be familiar with his moves by now. His great sword does a large amount of Fire damage as well as Slash. Even when behind him, some of his moves swing back, so DPS need to be careful. When he charges, stay out of the firey trail.
Thorpe is pretty chatty and you can use his voice lines to tell what is going to happen next.
- “Ha! Pathetic!” = he goes off the tank and attacks one of the other group members
- “This will be the last time we meet” = he rises and becomes invincible while he casts a beam that spawns two behemoths. Don’t get hit by the beam and kill the adds while the tank holds Thorpe away.
- “Prepare to have your soul crushed” = aka The Big Sticky Finger. Thorpe points a beam across the room and slowly rotates. It’s pretty slow so easy enough to stay away from or you can duck under it.
- “Time to taste Corrupted Steel” = slams down his sword – don’t be too close.
- “I will crush you beneath my heel, ant!” = he summons a beam of fire and directs it at one player, leaving a circle of fire on the floor.

Strategy and tips
Lazarus is a dungeon of puzzles, the first being the Door Room. Mobs spawn in front of a door with three spaces for symbols above it. The first symbol is lit up, and you need to stand on its match from the circle on the floor in the middle of the room. This will open the door and release more enemies, lighting up the next symbol, and so on. When the third symbol is activated, the door closes and another door to the right opens. The symbols are best activated by someone with range, usually the healer. The key is to open them fast enough to keep the fight flowing but not so fast the team gets overwhelmed. It’s good to kill the archers before moving to the next door.
When you get to Cilla, one person should run across to talk to her while the rest fight the enemies. The next fight, Alcyon the mage, can be challenging. The Overhead Staff attack does heavy Strike damage, while all his spells do Void. Look out for him raising his staff above his head and be ready to dodge. The two archers can also be problematic in this fight, so try to clear them early.Â
Be careful in the handwashing room, as using the fountain will spawn the mini-boss by the door. Make sure everyone is through before you wash your hands. Use the architecture in the room to get out of the ranged attacks line of sight to bring them to you, or just kill the archers quickly.
Main Damage Type: Arcane
Physical Phase: Cilla is a fairly straightforward fight, to begin with. While the tank holds her aggro, the DPS hit her from behind. She has a buff that increases stacks over time, making her hit harder. There are three ports in the floor, where a stone orb can emerge from. Once an orb has risen, you can interact with it to reset the stacks. This will also progress her into the next phase.
If you can withstand the damage through good tanking and healing, the game forces the next phase by reducing damage done to Cilla until the orb is pulled.
Magical Phase: In the magical phase, it is important that the team clump together. Cilla will cast a spell that makes each player leave a pool of Arcane damage at their feet. You have a few seconds to get to a clear area before she makes it explode. She also shoots out orbs that will root you in place if you touch them.
Main Damage Type: Strike and Arcane
Chardis is about the least mobile boss in the world of Aeternum. He is a giant stone automaton, who uses his detachable hands and a beam from his single eye to attempt to defeat you. When he first awakens, there will be an orb on each side of the room, trapped in a force field. You need to break the field to release the orb, which will spawn a mage over an orb port on the ground. Kill the mage and place the orb.
To fight Chardis, the whole group should stand at the edge of the arena closest to him, in a Sacred Ground. You can block or avoid most of his physical attacks. If you get a symbol over your head, it means you are going to drop a Slicer. Head to the back of the arena to drop it, then return to the fight.
After some time, Chardis will start beaming one player with his eye. This player needs to run to the orb that was placed previously, which will cause both the orb and Chardis to drop to the ground. Once down, players can do increased damage so be sure to use all your Oblivion and Rend to make the most of this advantage.
If there is no orb up, the beam will continue damaging the player it is on. With careful healing, lifesteal, etc, players can continue to fight Chardis while someone is being beamed. But where possible, the orb is always the better option. If an orb is available but not placed, everyone except the healer should work to place that orb.

Artifact: Void Darkplate Heavy Chestwear
Dropped by Nereid.
Strategy and tips
This is a very pirate-y expedition, with lots of explosions and gunshots. Watch out for bombers – you can root them and run, or if you’re clever you can lead them to their friends and use them as a weapon. To beat the mutation timer, players generally tend to skip past mobs and group them up. Be aware of ghosts and try to kill them rather than skipping, since they cast spells that slow you down.Â
Main Damage Type: Fire
The Admiral is a huge pirate with interesting feet and some really big balls. The fight seems deceptively simple at first, with everyone beating on him. He throws explosives, and if you see a red circle on the floor, you’re going to take some fire damage.
At about 75% health, he jumps up onto the ship at the back of the arena so you can’t hit him. He’ll usually spawn a group of minions at the same time. The Admiral throws down kegs and cannon balls, and lines of fire appear on the floor. The kegs drop a radius of black powder which causes a Fire DoT. You can pick up the cannon balls, load them into the two cannons at the side of the arena and use them to shoot Admiral Blackpower. After three shots, he will come back to the fight.
This happens again at 50% life and about 25%, with more fire lines each time, which you can just dodge through. At the end of the fight, after you pick up your bag, Admiral Blackpowder has one last explosive surprise.
Main Damage Type: Nature
Nereid is an interesting boss. First of all, she is Angry Earth, not Lost, so you’ll want to change your wards and coatings. She also has different Weaknesses to either regular Angry Earth or Lost – 30% Ice, 20% Strike.
Her attacks do a range of physical damage types, and she uses a Lightning spear, but the most troublesome part of this fight is the wind, which does Nature damage and pushes you around. So we recommend using some Nature protection to help out if you get stuck, and just avoiding the rest.
Nereid will fight in the centre of the arena and periodically spin along the cross pattern on the floor. It’s usually safest to stand on a diagonal, but be ready to move if she comes your way. There is a predictable pattern to her movement that you can learn. When Nereid moves to the centre of the arena and raises her staff, stand back and make sure you are on the diagonal. Gusts of wind will shoot out along the lines of the cross.
It’s possible to play this fight as ranged, from the edge of the room, as long as you keep an eye out for the tornados that circle the arena. Toward the end, there is a lot of wind and lightning (it’s very very frightening), so be careful of your positioning.
