Previous attempt
The final boss had about 25% HP left, and it was the second phase, but I made two mistakes and lost. Nothing, try again.
Night 1 (pic 1)
I got Poseidon's boon 25% to get a double reward (here and now I'll describe what the boon does, not its name). I used the trick "30% HP after the boss" to avoid the curse of Eris. I also got +20% HP and MP from Aphrodite. However, I didn't play skillfully enough, so I reached the final boss with quite a low amount of HP (I think 20 or 30). However, a little earlier I got Aphrodite's boon which restores all HP after the room if its amount is more than 80%. I bought a triple grenade from Charon which improved this boon (now it 53%) and a sandwich. All HP is fully restored, from now on - nothing difficult. Chronos was defeated on the first night.
Night 2
It was easy. Now I can get the Daedalus hammers. I take "+50% attack speed" and "attacks hit twice, but cost 5 MP" as well as Hestia's MP recovery (each attack on an enemy will restore 4 MP). This is three times the damage from attacks.
Night 3 (pic 2)
I do everything as usual and after region 2 I meet Eris. She gives me a bunch of resources and her "blessing". But I was below 50% HP, how is that? So DD also affects this. Maybe I rolled back the save (after each night I made a backup of the save). However, then I won. Her curse doesn't affect me much - in the end I only received 70..80% more damage.
Night 8
Time - 17:46, although the first night was 37:30
Night 13 (pic 3, 4)
I finally unlocked the Strength arcana. Now I'm confident in my bonuses and I'm taking vows level 32. I'm lucky, I'll get Zeus's boons "reserve 50 MP to hit enemies with lightning when attacking", Zeus's normal attack and the infusion boon "Minimum damage 50". I'll also get Hephaestus' boon "Reserve 30 MP to have a little armor in each room". This is a very effective build and I win without any problems.
Night 18 and 19 (losing)
As far as I understand, the game developers for some reason believe that the player must die. I had to do this twice, I rolled back my save many times to find Moss, but he only appeared in the first room. I also noticed that there were a lot of enemies on the surface in the reward rooms. It looks like some kind of "Hordes 4", because I had to fight 5 (!!!) waves of enemies. In any case, in two nights I found the necessary resources for the recipe.
Night 21 (rollback)
This is probably the only night where I lost and rolled back my save. Although I can't prove it, I'm still sure that it was a unfair game. I got an incredibly powerful build: Hestia's attack, which inflicts burns, Demeter's special attack, which freezes, and a double boon, which turns burns into damage instantly. However, in region 3, a full-fledged bacchanalia began: there must have been several dozen enemies on the screen at the same time. Or 10 satyrs with grenade launchers, and then I felt like I was in 2000s cover-based shooter with combat rolls. I didn't have enough time to beat Prometheus. I rolled back my save and decided that the game only requires 24 vows SF for the golden statue, and although I could have passed 32 straight away if I had played a little better, 24 would be enough to start with.
Night 21 (pic 5, 6)
And again it was not easy. When I played before I didn't think SF was harder than UW. However, I changed my mind. I got Hestia's boon "enemies explode and deal damage" which made it much easier to defeat a crowd of enemies. I didn't use the Hordes vow (+60% to the number of enemies) but it felt like there were even more enemies than with it. I got the hammer "attack hits twice at a cost of 5 MP". I had little HP left and I met Athena. Should I take DD? On the one hand, I had 90 HP left, which was clearly not enough, and on the other hand, I had 130 free MP, and this boon, which reserves 150 MP, would have halved my DPS. I took a chance and took it. And I was right, before Prometheus I found a little MP, now I had 5 MP and I could attack effectively. I won, but it felt difficult. In the following races, the number of enemies was much smaller (although Hordes was at the same level)
Intermission: Statues
I thought I'd get the golden statue right away, but after the first night on the surface without the curse at level 24 vows, I was simply shown that there were three statues to cover with blankets. I thought it was a scam, but the statues opened after each night. Ok.
Night 26 (pic 7)
So, the night before the first ending. I put 40 vows because I easily beat 32, and at that time I didn't have a weapon aspect pumped, there was no familiar, there were clearly weaker arcana. However, the build was very unsuccessful: Arachne gave a bonus of "100% damage from cast", and I only got the cast itself in the last shop, before the final boss. And I also spent the armor due to careless play. I didn't find the boon for attack at all. The first Daedalus Hammer I got was "your special attacks are doubled and attack 2 more enemies". Clearly not my favorite build. Next I get Hestia's burns for special attacks. This is bad because the speed of the special attack is quite low and I won't be able to deal much damage with burns. Then in the Fields I find "first burn deals addition 120 burns" and "burns deal damage faster". Okay, that's better. However, the hammer is again a failure: my favorites are "attack twice, spends 5 MP", which is not very useful when I don't have a boon for attacks. But now I can activate an arcana that increases the damage from hits when I have less than 100% mana with a simple attack, not omega moves. The other hammers were for omega moves, which in my case were generally useless. Then two more successes - I get the boon of Hephaestus "reserves MP, gives a little armor in each room" - this allows you to play more relaxed. And I finally get Apollo's boon "blinded enemies take more damage from backstabs". Okay, now my chances of winning are over 50%, and after the Sirens I was sure I would lose. The fight with Chronos was easy, I just "clicked" the final stage using infinite DD. I usually play on 50 vows, but without Rivals 4, so I don't have good skills against Rivals final bosses. I get the first ending.

Familiars:
I found it strange that Yi only destroyed this device after two peoples were killed. If he wanted to intervene, he could intervene immediately, without waiting for it. My first thought was that they needed to show how dangerous the device was to get more drama.
However, I just realized: Yi wanted two more "computing cores" added to the system. The fact that he stood calmly and waited simply further reveals his attitude towards people at that moment. And emphasizes the character's change in the good ending.
