Two neat things I've noticed now that the embargo on job actions was lifted. Spoilers for Endwalker, natch.
Firstly, the presence of "Zot Hypertuned" enemies, sharing the same model as "Inferno" from Castrum Abania. Suggesting to me that Zenos's pet projects, Hypertuning and the Resonance Chambers, may show up again in Endwalker.
Also of note is the presence of "Zot Armored Fiend" enemies, which are modeled after FFIV's take on a series staple, the Iron Giant. This version has a cannon and claw hand instead of a gigantic sword. Though I may be slightly mistaken in this claim, as while both the original FFII Iron Giant and the FFIV Iron Giant have the same name in English and Japanese (Iron Giant and Tetsukyojin), the spelling for their names uses entirely different lettering (FFII: テツキョジン, FFIV: てつきょじん). Still, I think it's neat to see this enemy.
Secondly, confirmation that the Magus Sisters are the final boss for the Tower of Zot dungeon. This means that only one of Endwalker's Trial bosses is known at this moment: Anima. The rest are a mystery. Given that their usual placement in the story is levels X3, X7/X9, and X0, I can't help but wonder when and where they'll be fought.
