Let's talk about Diadem mechanics

[SaitoHikari]

Yeah, I figured we needed a theory/infodump thread on exactly how the new Diadem works, hopefully without being drowned by everything else about what people think about it elsewhere in the forums.

So far, things seem quite random, but I did notice a few things - and it's quite likely that boss FATEs and even the emergency mission itself might have specific trigger conditions.

----

Every 10.000 Evaluation triggers Emergency.

Unconfirmed but definitely worth testing, if at all possible. Literally the ONLY way to test if this is true is to get a full 8-9 parties to enter Diadem in a fresh instance and keep track of Evaluation gains across all parties, which is near impossible to organize (and perhaps very intentional by the devs). Anecdotal observations from many players indicate that EM spawns at a far higher rate in Matron than in Fury, and Matron gatherers gain Evaluation at about double the rate than Fury players (as Fury parties tend to just AFK and wait for boss FATEs/EMs after the initial objective is completed). Evaluation building is also the only thing that is common between both Diadem modes.

Also, I realize not everyone checks Reddit (on top of their godawful formatting), so if you run into an Emergency Mission, here's the guide for it. And yes, you DO need a guide for the Emergency Mission, because one mistake CAN wipe the instance and render it unwinnable since bosses gain an attack up debuff for each one still alive + do not reset upon a wipe.

Basically to sum it up, priority is Presidential Hounds (center) though kill the woes that spawn directly in the center first -> Any further Woes that spawn that are close to the center (though disengage to deal with Ice or Lightning Elemental Sprites accordingly) -> Elemental Lions -> Crystals. If a Legatus dies, kill the crystal behind it, it will stop Woes from spawning from that direction. Kill the final crystal after all other adds are dead.

BE SURE LIGHTNING AND ESPECIALLY ICE LEGATUS STAYS AWAY FROM THE CENTER, ICE AND LIGHTNING ADDS SPAWN ACCORDING TO WHERE THEY ARE, AND 90% OF EMERGENCY MISSIONS FAIL BECAUSE THEIR AOES CROSS INTO OTHER GROUPS AND ESPECIALLY WITHIN STRIKING RANGE OF THE CENTRAL PILLAR THAT FREES BUER EARLY AND CAUSES TOTAL FAILURE IF BROKEN, WHICH TAKES DAMAGE FROM ALL AoEs BY THE WAY, NOT JUST THE WOES. Ideally once the center is cleared out, the center party should assist with killing Ice or Lightning first. (I don't know what Wind does, but you never hear about Wind going out of control and it's often the first one killed anyway...)

Found a gathering map on Reddit. No idea who created it, but credits to him/her.

- 'Corrupted Sprites' have a chance of spawning after each successful FATE, regardless of whether or not it involved a damage/debuff field. Killing one awards you a treasure coffer. (CONFIRMED)

REGARDING BOSS FATEs:

It is highly, HIGHLY probable that Boss FATEs are actually completely random, depending on weather/Eorzea time, as all of them can be observed spawning in Matron too, where nobody really does FATEs there at all. I have even observed Brachiosaurus spawning in Matron, meaning the Baby Brachiosaurus FATE has nothing to do with it at all. Even though some have observed Brachiosaurus outside of Fog, be aware it is a 30 minute FATE (meaning weather will cycle twice during that time period), what matters is the weather at the time that the FATE spawns.

We can rule out Evaluation being a factor in Boss FATE spawn, because a fresh Diadem instance will ALWAYS begin with at least one boss FATE spawn. There is also likely a timer between boss FATE spawns. (You can tell if you're in a fresh instance if you open your map upon loading in and notice FATEs popping into existence with every single one of them having 3-5 minute timers, along with buried coffers being found on each island and cave.)

https://www.reddit.com/r/ffxiv/comme...ther_relation/

Secret of the Lost Legend (Brachiosaurus): Spawns only in Fog during AM hours. (CONFIRMED)
Embrace of the Serpent: Spawns only in Fog during PM hours.
Purple Haze (Worm): Spawns only in Gales.
Where's the Beef: Spawns only in Umbral Wind.
On the Inside: Spawns only in Clear Skies.

On that note...

Blood Wings (Pegasus) is a special FATE where you fight a Pegasus, and it has the same rewards as a boss FATE (1 lockbox, 50 damaged boxes), except the actual target is a Rank V monster instead of a full fledged boss. It also has a chance of dropping the baby pegasus minion. Spawn condition is to clear 'Darker than the Blackest Witch' FATE, but with one major detail: The unicorns have to be running in a circle, in which Blood Wings will spawn 2-3 minutes after completion. If they're not, clearing the FATE just has the same FATE respawn after 1-2 minutes. (CONFIRMED), thanks to Astronym Stormlove for the circle observation.

(Be aware that FATE spawning doesn't apply when Eorzea Time crosses into 12 AM - 11:59 AM, where no unicorns are present.)



Note that to reach the platform where the Pegasus is on, you have to run to a whirlwind on the far northern end of the lower Diadem island, meaning that the platform was created specifically for this FATE (as there is nothing else up there). And be aware that fighting the Pegasus is arguably harder than fighting most of the real boss FATEs - it begins by casting a 20 second Confuse in an AoE, so don't pop your attack buffs immediately or you may end up killing your healers.

There have also been sightings of the Proto Ultima Raffalesia spawning at night time in various locations around Lower Diadem, most notably near where bosses spawn. Unknown if they drop Proto Ultima Exoplating when killed, but they supposedly did in the previous version of Diadem. Need observations to determine exactly when and where they spawn, if not random.

As said in another thread the day/night cycle seems to influence enemy type spawns (those monkey dogs seems to be up only at night for example) as such this might have implication with boss spawn too

Btw I saw the pegasus/unicorn in the pool in the south dunno if it has to do with anything but wanted to give the sigh location just to be sure

The pegasus seems to stop for a while whenever it walks into a fate. Maybe we need to defeat the fates that are stopping it? maybe it has it's own timer that it needs to reach a spot before it despawns?

[A_Hortensia]

So far people I've qued with have only wanted to fate grind after objectives.

Waiting to go in with my LS so that we can actually learn.
Though I'm hoping by then someone will have figured out something so that we can get more out of it.

I really don't think Diadem was locked out and re-released to be a fate grind.
There's very obviously more to it, I just can't figure it out.

[SaitoHikari]

I forgot, I actually streamed my last Diadem run. I should actually stream all of them for data collection purposes, although I don't have Twitch Pro or whatever, meaning that everything I record gets lost to the void after 2 weeks or so.

Of particular interest is what happens at 1 hour and 3 minutes. As soon as the Baby Brachiosaur dies, the fate 'Slaughter of the Lost Legend' spawns IMMEDIATELY.

EDIT: Asked a few more people, some had their maps trained to the island the entire time to watch for the Baby Brachiosaurus FATE, only to end up watching the actual boss FATE spawn without observing the other FATE ever appearing. Of particular interest is that the actual text of the Baby Brachiosaurus FATE may be a hint - it mentions that if the Baby Brachiosaurus are left alone, they may grow up into something dangerous. It's only a theory though. Another friend also tried killing non-FATE Baby Brachiosaurus to see if the FATE could be force spawned, only to fail, so either what happened in my video was either an amazing coincidence (which I doubt) or there's a timed aspect to it as well.

Also watch what happens at 50 minutes onward if you want a laugh. (Involves the Wisent boss fate)

Oh, also... I've noticed other FATEs with unique names that only spawn in one place, especially the one called 'NOT THE TREES'. I've never done that FATE personally, but is there anyone in here that can share what they've observed on it? What triggers it to spawn, and what happens after clearing it?

[KageTokage]

NOT THE TREES is just a standard tier V monster FATE. Most of the lower islands have a unique set of monsters and unique FATEs to go along with them.

I feel like those are probably the most efficient for farming lockboxes as far as time spent vs. reward goes.

[A_Hortensia]

I can confirmed Corrupted Sprites popping after successful FATE clears;
And they produce chests. ( ' w ')b
Reward for Purple Haze was 50 damaged Lockboxes and 1 Lockbox.

Some mobs have cleave abilities without telegraphs, can be dodged in the same fashion as large beasts like those from The Stone Vigil (Hard).
Rank II mobs very difficult to solo.
Rank III; I couldn't. I tried. :P

[Culfinrandir]

Following the Pegasus took us to an Aetherial Rift that launched us into a cave with FATEs that seemed to give better rewards, even if gold wasn't achieved. They require more players though & it can be like herding cats at times. Several people tried to walk into the cave but a magical barrier prevents it, clicking on the Rift was too difficult because they'd have to dismount. -_-

[Remedi]

Oh about the purple worm he tends to attack any enemy nears it (the FATE description says it devours anything as such it's fitting) as such don't be too trigger happy if you see him rushing to something

[Moomba33]

I've been twice so far and unfortunately both times people started leaving en masse once the objectives were done and there were no boss FATEs up. It'd be cool if reasons to stay and clear normal FATEs were discovered to trigger special events.
