Scorn of the Machina of Destruction trial (Aigaion) is due soon. Here's some early tips to help prepare for the fight so you can get that nice 2H fist for your new King Rain!

Just for reference, here's some of the early tips for other trials still not released that I've posted:

Soul Palace Eltira

Reminder that this is all based on the JP version. There may be changes when it releases to Global.

Wiki page: https://exvius.gamepedia.com/Scorn_of_the_Machina_of_Destruction

Note: I used temporary translations until the official translations are added. I figured they're easier to read than Skill ID numbers as a placeholders. I'll update the skill names to the official translations when it's patched into the global client. Official translations are in!

General Tips

• Race: Machine (Body, Stage 3 Arms), Demon (Stage 1&2 Left Arm), Beast (Stage 1&2 Right Arm)
• Body: -30% Lightning and Light resist, Neutral otherwise
• Left Arm 1&2: -50% Light, 100% Dark resist
• Right Arm 1&2: -50% Ice, 100% Water resist
• Left and Right Arm #3: -50% Water and Earth, 50% Lightning and Light resist
• Body: ATK/MAG breaks only. Arms: DEF/SPR breaks only.
• Ailments used: Body: None. Arms: ST Blind, Disease, Paralyze, Stop, Death
• Elements used: Body: Lightning. Arms: Fire and Dark
• Arms will counter-attack with a physical attack of their own (can be covered/evaded). Body counters light/lightning with aoe fixed lightning.

Body Mechanics

While the arms are alive, Aigaion's body will have Space Distorion active always. This is a buff you can't remove that gives him 300% resist to every element and 300% DEF/SPR. This will make him near invulnerable to damage (though not completely, see cheese method below). The way to make him drop this buff is to kill his arms. There are three sets of arms in total, and once the third set dies his shield will go away permanently, allowing you to deal actual damage to the body.

While arms are alive, all the body will do is refresh his shield buff, and cast Genocide Beam (aoe fixed magic damage) every three turns (starting from 2). When the arms die, the body will "wake up" and start casting lots of Core Laser (ST magic damage), and will start charging up a super-attack with the signal "Plasma is concentrating at the core!" This skill will self-cleanse his breaks, so make sure you re-break him! When you see this warning, you need to hit the body with light elemental damage to weaken the incoming nuke. If you used light element, the followup attack will be Universe Destroyer (aoe 5x fixed magic). If you didn't hit the body with light, the followup will be Universe Annihlation (aoe 8.57x fixed magic).

The body will also counter-attack light or lightning damage with Electromagnetic Explosion, which is an aoe fixed hybrid lightning element attack (lightning resist helps with this).

The body will ressurect both arms after three turns have passed, until all arms are defeated (three sets). After the third set dies he remains permanently in active mode and won't put up the shield. When the body goes under 40% health he gets more aggressive and uses his super attacks more often.

Arm Mechanics

One important point about the arms are the counter-attacks. These counters are multi-hit and can chain. If you're covering them with an evade tank, they don't do any damage, but if you're not using evade, these chaining counters can possibly deal some decent damage.

The first set of arms will do AoE dark magic damage, and AoE fire physical damage. If you're using a physical cover tank, you only want some dark resist on the team (or maybe just a buff). One of the arms will sometimes use a break resistance buff on the enemies, so be sure to dispel this so you can re-apply breaks. There will also sometimes be an AoE heal, and an AoE man-killer buff (dispellable).

The second set of arms are the same as the first, with some new skills. One arm will start using ST Stop, and the other will start using AoE atk/mag buff.

The third set of arms use new skills. They stop using the fire/dark attacks, and now the left arm uses ST stop and ST death/paralyze/disease. The death can be immuned with death resist. The right arm starts using more buffs, like a def/spr buff and AoE reflect.

The Cheese Method

For those of you who aren't ready to do this trial the "normal" way, here's a very easy, very slow way you can go in and kill the boss just to claim that fist weapon, but will fail the UoC mission. This will take something like 60-90 minutes (or more), so only suffer through this if you really want that fist, but don't think you can handle the full trial.

The catch with the body's shield is that it does not give immunity to non-elemental damage. This means, even though it has a 300% unremovable def/spr/resist buff, you can still technically harm the body with non-elemental damage, at a massively reduced rate because of the def/spr buff. In order to cheese the fight, you want to kill off the first right arm (to disable the healing), then leave the left arm alive and focus on the body. As long as at least one arm is alive, the boss won't revive them, and won't shift phases (which means he never uses core laser, universe destroyer, electomagnetic explosion, or his cleanse buffs).

With this method, the only damage you take is the AoE fixed genocide beam once per 3 turns, the AoE dark magic from the left arm (can immune with 100% dark resist), and the physical attacks/counters (can be covered/evaded).

You just slowly chip away at the body with non-elem damage until it's dead, then you finish off the last arm. This is very slow, boring, tedious, but also super easy and safe. I used this method on my very first Aigaion clear in JP when my account wasn't ready for the body's final phase. It took two Bartz chaining non-elem on the body about 110 turns (70'ish minutes) to win. I got the fist and ran it through itemworld before it closed that week, but it was not fun.

An example team for this setup would be:

• Cover ptank
• ATK/MAG breaker for body
• Healer that can w-skill heal mana regen
• Buffer that can mitigate stat buff
• ST non-elem chainer that can just hit repeat every round
• ST non-elem chainer that can just hit repeat every round

A team like this can kill off the right arm, then set their skills and literally hit repeat every round without any thought, allowing you to cheese the trial while watching TV or something.

Strategy Summary

Here's a recap of the basics for the fight:

• Provoker with death immunity
• Physical cover tank for the arm counters (optional)
• Magic cover, or provoker for the core laser (optional)
• High spirit for everyone for the aoe fixed magic attacks
• A way to deal light element damage to the body to weaken his universe attacks
• On-demand breaks to re-break after the boss cleanses himself, which happens every other turn below 40%

Video Example of the fight

Here's my all mission clear (not cheese) from the JP server:
https://www.youtube.com/watch?v=a2Mi3Q31rRU

That clear uses lots of units not available to GL yet, but I feel it's comparable to GL's power level at the moment. CG Dark Fina is about equal to GL Sol in terms of power, and King Rain is much stronger than her.

Here's my cheese method clear, with 90% of the video edited out (the boring repeat rounds):
https://www.youtube.com/watch?v=MiIf1ozXtFY

That team used my example cheese team to just hit repeat every round after dealing with the right arm.

Update

I went back and tested the fight again on JP, and with proper breaks and buffs, the incoming damage is a lot more manageable than I had remembered. I've edited the tips somewhat to reflect that you probably need less survival than I originally suggested.
