So this is our thought process when it came to deciphering Fate Calibration Alpha and obtaining the Enigma Codex. You either need to be a tin foil hat wearer or watch a lot of Rick and Morty to solve this mechanic.

When we first saw Fate Calibration we didn't have a clue what was going on. Boss just stands still and then annihilates your team with either a motion/still mechanic and then lasers + other mechanics. We said to ourselves we need more data so we went back to see if there a pattern. We split up into 4/4 groups trying different things. Half the group would move and half the group would stay still to at least see what was going on with the lasers what hidden mechanics existed. As it turns out there didn't seem to be any sort of role pattern and we could not predict still/motion.

The boss says the following in English when starting his cast "Difference engine fully powered... Beginning future simulation...". Future simulation made sense to me at the time but difference engine seems to state that he is basing this off of something that has already happened. He will do the opposite of whatever has previously happened. This was our first mistake.

We looked at Perfect Alexander during the previous phase to see if there was any correlation between his order of motion/stillness and what happens during Alpha. There didn't seem to be any but that doesn't make any sense? There has to be something! We kept pulling and some of us had the dumb idea of thinking the boss was doing a "diff" on my movement during the cast bar. If I would stand still then the boss would do motion next. Specifically the group stacked up in a line in front of the boss in a specific order not moving. After two pulls this was deemed incorrect and seemed to not influence the mechanic at all.

We checked if the mechanics players got earlier in the fight in anyway influenced what we got there. Why else would SE give you such a long cast time? It's clearly so you can watch footage or think back to previous phases and remember what mechanics you got. This was quickly shown to not be the case especially since the defamation seemed to represent no pattern.

Next we got hit with the biggest bamboozle of all time. PERFECT ALEXANDER GLOWS AT IRREGULAR INTERVALS. Perfect Alexander will glow randomly during his casts and during the fight. This is great because we have plenty of footage of this from our previous attempts. What's even more evidence is that we have footage of Perfect Alexander turning his glow on and off during Fate Calibration Alpha at 25% intervals. This has to mean something! So now we know that the boss can glow up four times during Fate Calibration Alpha and there are four robots. Cool this makes sense but we need to consider what a double glow means. If the boss glows from 25-75% this would correlate to two safe robots. Furthermore we noticed the glow wasn't exactly correct in determining the safe spot UNLESS you read the robots from right to left instead of left to right. This was also proved somewhat inconclusive. But then we thought maybe it depends on if hes glowing during motion/stillness at the start of the fight. What if he is glowing during the start of Fate Projection Alpha. Maybe this means the boss is inverting everything he has done so far. It is the boss using a "Difference engine" after all.

As you can probably tell by now this got really complicated really fast. Some of us were dead set on the glow being the solution while others were not convinced and pretty sure this was just a weather effect of the zone. The zone has strange lighting in the background where a bunch of light seems to be pulled to a blackhole. We couldn't say for sure what was going on.

Going back to what the boss was saying in the RP text "Difference engine fully powered... Beginning future simulation...". The word future means this might have something to do with time. We noticed early on that Brute Justice and Cruise Chaser had an Enigma Codex buff that "gives the power to control time". I asked about the lore behind this in the games story and was told "The goblins used it to control Alexander". Why would the developers give the two side bosses this buff and do absolutely nothing with it? There must be SOMETHING we can do to obtain that buff. We were far enough along in the fight that given the boss's HP we were pretty sure we were done with Brute Justice and Cruise Chaser. Its possible they would drop the buff later in the fight and this is a completely lost cause.

We played around in the burn phase and found zero interaction. The only thing you can really do there is let them enrage, kill them, or walk around inside them. No Monk One Ilm Punch memes here. We started looking at previous phases at this point. Wormhole interaction was minimal and everything that could be done was done while we were figuring out strats. Fun fact our original strat had the 3rd/4th person placing Brute Justice in front of Alexander and shooting down mid in a straight lined cone. Placing Brute Justice on a void puddle is a pretty common thing early on so we know that did nothing.

We started looking at what we could interact with during Inception. We decided to try doing inception without one judgement and placing it in the middle of the room. Cruise Chaser would spawn on the crystal, blow it up, and do SOMETHING. We would then bait Brute Justice on top of a crystal which was pretty easy to test. This seems to make a lot of sense since the heart can be slowed and you only need three crystals to do Inception since if no crystal explodes then you know its the empty spot. The heart's HP is also pretty low meaning we could kill it before it reached the middle of the room with cds easily. The theory didn't work but during one of the attempts we messed up and had some orbs blow up so we couldn't kill the heart. The heart ate the crystal and gained a stack of damage taken down. I thought nothing of it and we went to bed.

We were tied as fuck at this point and really confused. I was dead set on just going back to Fate Calibration Alpha at this point and figuring it out. I was getting a bit upset that my group was throwing this hard by testing out dumb as fuck crazy theories. In UWU they said "Predation must be a bug". We just didn't understand the mechanic and the situation has to be the same here.

We all decided to sleep on it while Clees was looking at videos trying to come up with literally anything. While sleeping a bunch of us had the idea that we had one last interaction to test. I kinda skimmed the chat but I know Sfia specifically pointed this stack out. What if we give the heart four stacks? I was pretty tilted at this point to be quite honest. I figured this was a waste of time. How do you even solve inception anyway with no crystals. This was no easy task to execute anyway. The damage seemed insanely high and if you place two judgement crystals on top of each other they begin to pulse and explode. While pulsing they can't be taken by the heart.

We tried creating a line with our crystals but that doesn't work either since Alexander will just blow one up. This means you can only feed three crystals in a line. We saw that the heart's hitbox was about that of a waymark and decided to go with a box strat. We would use tank lb3 + all tank cds to at least see what would happen. Unless the damage was a 10million damage one shot the tanks could at least live. As it just so happens a close proximity damage crystal is not 10million damage. Gave that a shot and to our surprise the heart turned gold and gave us all a buff.

Killed the fight the very same day we got the buff. Thanks for reading.
