Elf: Go edit that into Xorn's entry in the G3 topic, then! ...but yeah, Darkness doesn't OHKO the Auras anyway, and I'm not sure it's close enough to overcome the regeneration, so that leaves Death Knell's GT. Not happening in time.
Re Nergal, yeah, that was a result of a quick glance at the stat topic saying "See stats above!" Average cast damage of 21 vs. 10 RES. Nergal has 30 RES. Okay, so immune to stuff that isn't Forblaze / Aureola / etc. ???
Jo'ou: I did say *inclination*. It's the same issue as Dario, we usually let bosses have perfect AI in the DL, how much does it mean if the AI is "cheesable" in-game by forcing the boss into doing what you want if you know what you're doing? Yes, Cathedral can be controlled by the human player into doing whatever you want, but bosses with rigidly fixed scripts are "already" controlled to do something, and that is exploitable by a human player too (see: P3 / P4 superbosses like Margaret, where you look up the attack order and switch personas who resist the next attack & defend with characters who'd have their weakness hit). I'm certainly not on board with forcing Kefka to uselessly open with Fallen One vs. bosses. The point is, this kind of "figure out what the acceptable AI translation from in-game to DL" is an art, not a science. If it makes you feel any better, I probably do grudgingly hold Cathedral to enforcing the rules on Wheel of Memory, but if there's any kind of tiebreak needed where a looser interp of Cathedral's AI would allow it to win, that would be fine. (Note that just as holistically Cathedral's AI is something it gets punished for too heavily - I certainly had no clue that White Robe was so bad at killing - Cathedral's ID is something that holistically sucks in-game, but is badass in the DL where there's no party members to switch with! Blah. The holistic Cathedral loses the ID but gains not being stuck in White Robe, the strict version has BS ID and not much else.)
As an additional complication for Wheel of Memory... okay, in XS2 this can never happen so there's strong reason to holistically kneejerk against, but Melville is from a turn-based game where there's a lag between entering commands & executing them. Usually this isn't woth caring about in the DL, but sometimes it comes up, most notably Pokemon with Protect where you have to enforce that kind of mind-games rules (Protect vs. someone with a single big shot of damage doesn't work if the other dueler "knows" Protect is coming!). Anyway, Cathedral can threaten to make Melville waste some turns whenever their turn order is close enough; if there's a Melville inputs command -> Cathedral -> Melville executes command sequence, Melville has to consider that Cathedral might use Wheel of Memory, and thus Melville will have to consider passing. This gives Cathedral free turns to do damage if Melville is very conservative & Cathedral only uses Wheel of Memory rarely, or if Melville is aggressive he just wakes up Call to Arms. I'm not sure I give this argument much credit, but it's something to consider.
Jo'ou, re Beatrix: So what that it's a timed fight? That certainly isn't a reason to disqualify it (and I believe you can still Game Over the fight, it doesn't just continue if you die, at least for some of the fights). Also, checking chat, it seems boss Beatrix does have a OHKO, and even if she doesn't, the dark spectre of FF9 boss speed hype might mean she doubles before the time limit is up anyway. So yeah.
