Does Leviathan Cheat?

[Ooshima]

Put simply, your DPS were too good for the fight and pushed his phase. Which results in Leviathan going "lolno" and killing you no matter what.
My advice is to stop damaging Leviathan as soon as Mercy Stroke and Misery's End pop up, as he seems to hit his "NOPE" button around 17%.

There are actually a couple of fights where over DPS can be a problem. Wiped in Titan EX once due to over DPS. Twintania and Raffelsia needs to control phase changes if not it could be messy.

We had to stop our Summoners from using Bane during the final nail phase of Ifrit Extreme because it would push him into the hard enrage.

Fun times.

I understand having to hold dps for phase switches and control, but something like Ifrit's hard enrage or apparently Leviathan just wiping your group on the shield are incredibly poor mechanics. Instead of things like the original Pharos Sirius, where rapid dps could make the fight harder, there is not warning that you are doing too well and is a huge slap in the face for a group that is executing the fight well.

If they are going to have a fight that is about controlling DPS, thats fine - Pharos Sirius was full of good examples of those mechanics. Holding for phase transitions is ok, but would make more sense if we could see the enemy's HP as a percentage, so that parsers are not needed. Wiping because your dps was too high through the entire fight with no warning is just plain infuriating and poor design.

Actually.. I've never personally encountered that. What's the Ifrit sudden hard enrage about? For me there were once we fought Ifrit EX with 3 BRDs and we DoT the hell out of every single nail and ended up like half of them exploded back-to-back (with probably time spare before he cast hellfire) and that resulted a wipe

Pretty much the same as here. If Ifrit hits a certain % while the final nails are still up he will just wipe the party with a nails still up Hellfire. I'm assuming it's there to make sure you don't just ignore the last nail phase and just burn Ifrit down.

Can't stop DoTs already on Ifrit from ticking though so sometimes accidents happen when the DoTs push him below the threshold.

As Vaer said, if Ifrit's health gets too low during nail phase, he just jumps right away and wipes your party. I've run into it a few times while in DF trying to unlock Leviathan. I was so frustrated the first time it happened because in no way did it feel like a fair wipe. We had everyone up, had downed just under half the nails, and had ~10 minutes left in the duty, and then even though we were following the mechanics, Ifrit decided to wipe us.
