All the Octopath this week, I see...
Yuna (Final Fantasy X) vs Simeon (Octopath Traveler)
Sephiroth (Final Fantasy VII) vs Alisa Reinford (Trails of Cold Steel)
Shadow Namatame (Persona 4) vs Miguel (Octopath Travler)
Miguel debuffs the wrong stat here. While Namatame's elemental damage pre-Quad Converge is pretty pathetic, I'm used to thinking of landing multiple breaks on an 8PT boss as usually being fatal. That said... hmm, Miguel doesn't get more shield points post-break, so he's always broken in 2 spells. That said, if he survives the first break and then resolves a full focused Hurl Spear, that probably smashes Namatame. Both of these bosses are a bit overrated by smart AI in the DL of course (Namatame for hitting the right weakness, Miguel timing the Hurl Spear correctly). I think Miguel takes it off the stat topic, although you can argue Miguel is overrated by the "suggested level" for Alfyn's C3 really being lower than it should (he's scarier unscaled than most of the later C3s).
EDIT: Eh, I feel like Miguel needs more judgment calls in his favor than Namatame here.
Heavy
Arnaud G. Vasquez (Wild ARMs 4) vs Claude (Fire Emblem: Three Houses)
Arnaud's strategy is Lock Out -> Illusion -> Extend -> Win. Claude... still doubles with a Brave Bow+ and easily one-turns if all the shots hit, but think he barely misses the KO if only 3 hits connect, and even getting 3/4 is a lot to ask vs. Arnaud. A rare time where DL Claude would rather go Archer (like he probably does in-game) rather than Brigand for Hit +20. Ignatz > Arnaud hype?!
Tohru Adachi (Persona 4) vs Erik (Dragon Quest XI: Echoes of an Elusive Age)
DQ11 has unusually good status blockers for a DQ, so just block or resist ID. Could argue that Evil Smile -> Ghastly Wail still works, and Fear is a great status to land anyway, but if it's only 50%, Adachi isn't living to get 2 attempts off.
Middle
Miakis (Suikoden V) vs Ophilia Clement (Octopath Travler)
A 3 BP Holy Light deals 0.67 PCHP damage (to the 1/2/3/4 combined turn average), although Miakis's default equips have bad magic resist. Miakis's healing is 0.42 PCHP. So if no doubles are incoming and Ophilia is sitting on 5 BP, 0.67 - 0.42 + 0.50 (a 2 BP burst) = 0.75 PCHP to average MRes. Miakis has 0.90 PCHP. If MRes is straight-up subtractive, she takes an extra 50 damage every magic hit, so + 0.20 PCHP damage = Miakis is dead? Dhyer, back me up here. If S5 MRes means less (although it clearly means SOMETHING, you can watch Georg get owned), then it's a contest of who runs out of MP first, which is probably a Miakis win. (Unless Miakis has a Fury strat that works here?!)
EDIT: Apparently Miakis can hope that her high Magic score means a free damage-halved proc kicks in? Which even with a fair amount of disrespect due to the whole cast having that, probably is enough to tip things here.
Tifa Lockhart (Final Fantasy VII) vs Cerya Phoraena (Tactics Ogre: Let Us Cling Together)
Nergal (Fire Emblem: Blazing Sword) vs Maya Amano (Persona 2: Eternal Punishment)
Light
Viktor (Suikoden) vs Primrose Azelhart (Octopath Traveler)
While Prim probably wins a "fair" slugfest, according to Dhyer's topic, the entire goddamn Suiko2 cast halves Dark by default off Silver Hats. S2 Viktor should probably take it if Primrose's damage is halved? Although there's certainly an argument for scaling down such an easily universal resistance, or possibly allowing Primrose Allure summons as a "compensation" thing to get around her being Dark-locked. So definitely fine with a Primrose vote, but probably only via switching to the Anything Goes rules and damage average in 8PT.
