MYRIAD DEATH GUIDE : Achievements

Are There Any Unobtainable Achievements?
I apologize if some parts feel unnatural, as I am translating from Japanese.
Here is a list of the difficult achievements in MYRIAD DEATH. Some of them are not just difficult but borderline impossible. I’ll start by tackling the ones I can figure out.
Difficult Achievements
Congratulations
Mori is celebrated by YAGOO
YAGOO is the nickname of Motoaki Tanigo, the CEO of Cover Corporation. Hololive is operated by Cover.
Big Pig Man has a chance to transform into YAGOO. Instead of bullets, his gun shoots money. Defeating him rewards you with a huge amount of cash—just as expected from a CEO.

Sudden Crisis
Completed floor 1 where the mass outbreak of Minotaur is happening
There is a chance that all enemies on Floor 1 will turn into Minotaurs. I’ve only encountered this twice so far, so the probability seems pretty low.
When they turn into Minotaurs, a special event conversation will trigger.

The difficulty of this achievement and “Unprepared Mori” is quite high. As a countermeasure, it’s recommended to bring the equipment you can buy with Enemy Souls from the start.
Procedure
①Buy strong equipment with Enemy Souls.
②Once you’ve bought the equipment, jump into the gate.
③If an event doesn’t trigger, return to the title screen.
④Don’t select “Continue” and go back to the room in the Underworld.
⑤Since you’ll be back in the state before you made the purchase, repeat the process.
Since only Minotaurs will appear, it’s easier to fight with powerful ranged equipment. When you’re trapped in a room, make sure to fight while keeping your distance.

If you run out of things to buy with Enemy Souls… just do your best with the existing equipment. I think the boss is weak, so the real challenge is the path leading to the boss.
Fragmented Memories
In Area 4, you’ll achieve the objective by embedding a heart into the stone with a heart-shaped indentation. The heart can be obtained from the fleeing treasure chest (confirmed in Area 3-B). If you play through a few times, you’ll likely encounter it.
However, make sure to thoroughly explore the floor.

The boss in Area 1 changes randomly. It seems that it’s also selected when restarting, so it’s easier if you purchase a stronger weapon with Enemy Souls and keep re-running until you encounter it.
Ranged attacks don’t work, and only close-range attacks can deal damage. When the boss’s health drops below half, it will perform a wide-area attack at some point. Getting hit by this will result in instant death, so you need to dodge roll to avoid it.
The strategy is to stop using combos when the boss’s health is around half, and instead, attack one hit at a time. When the boss marks a wide-area attack, dodge roll to avoid it. Then, just continue attacking normally, and you’ll defeat it.

A safer method is to reduce the boss’s health to half, then attack with a ranged fire-effect weapon from the wall directly beneath the boss. This way, you’ll be outside the range of the wide-area attack and can easily avoid it.
The activation conditions for this wide-area attack are still unclear. It will always trigger at least once when the boss’s health drops below half. I’ve seen it happen even with ranged equipment that has an electric, so it might not necessarily need to be a burning effect.
Unprepared Mori
Completed floor 5 after direct transfer without enough equipment
The activation conditions and countermeasures are the same as “Sudden Crisis.” However, in this case, you’re teleported to Floor 5, and the boss is Ouroboros, making it more difficult. Fortunately, I had a strong ranged laser left, so I was able to achieve it without much trouble, but I wonder if this can be done with just the starting equipment?
Elite Destroyer&Goddeath of Destruction
You can achieve this by destroying 44,444 objects and 444,444 objects, but this seems impossible, right? Well, theoretically it’s possible, but it clearly feels like the number is off by one digit.
