Some notes on my UO views:
-I'd take enemy atk as higher than 60, myself. Not sure exactly where. For today's voting I'll just exponentiate the durability figures by 0.75 and call it a day.
-I probably reduce the potency of first-strike moves in some way... even excluding War Horn as largely DL-useless, about 36% of the cast has one (I may have miscounted) but only 20% of the cast can use them in-game. One option is just to cut the potency of first strike moves to reflect this.
-The most "fair" way to take speed is probably literal first turn but then no doubleturning until the next "combat" which is in 3 turns. I might just half the SD effect instead though, so each SD is 12.5%. Works for today.
-Cavalry do +41% to infantry (there's a pretty strong case to take this higher... open to arguments), this is factored into the average. Average needs to be lowered a little from the cut to initiative damage. Call it 44 today.
Alain: ~283/~191 (still nuts), about 129% speed, 83% damage or 47% with the draining.
Alain vs. Rubicant: As mentioned, Alain might take a hit without resisting fire, which is impressive for a PC. Doesn't matter.
Alain vs. Marcello (DQ8): Marcello does 41%, Alain can use Lean Edge to buy himself an extra turn. Two Spinning Edges and two Lean Edges is 260%, DQ8 boss HP gives me headaches but no way Marcello hits that to me.
Alain vs. Sierra: I think Alain barely misses the OHKO to me (takes it if we increase the cav bonus) but... that means Stealer of Souls actually doesn't fully heal Sierra so he kills her next turn.
Alain vs. Emily: Emily... 3HKOs before Noble Guard which definitely slows Emily down a bit, even though the ITD is there. Lean Edge probably not worth it against Emily evade, Spinning Edge 2HKOs as always but after accuracy it's probably 3HKO. So Alain wins on turn 4, by which time Emily has gotten two shots of full damage and two which are resited to varying degrees. That's probably enough. Close!
Alain vs. Celes: Vanish.
Alain vs. Yuri: Yuri gets rolling which is probably too much.
Alain vs. Nailah: For what it's worth I would definitely consider Nailah infantry, bestrals are after all. That said Savage dealing +72 ITD damage is lethal with any RD kill point and she's getting it off unless Alain wins in two turns (80% over three Nailah doubles).
Alain vs. Lashiec: Lashiec 3HKOs to me, but Alain also has a 3:2 so he gets off the draining he needs to stay afloat. Reinforce might be scary there at the end if Alain couldn't blitz with Spinning Edge, but y'know he can.
Alain vs. Teepo: Teepo only 4HKOs even below half HP so Lean Edge eats him.
Alain vs. Jessica: Really think so.
Alain vs. Alena: NES Alena might have the faintest glimmer of a chance but I don't vote on that these days.
Alain vs. Chaz: Yeah Lean Edge heal-locks unless Chaz opts for shields, so he does that. The issue is that Chaz only does 29% with Megid anyway and needs to stop to heal every two turns... yeah, not close.
Alain vs. Artea: Again, heal-lock with Lean Edge.
Alain vs. Eirika: Eirika is the only dueller in the field Alain doesn't hit weakness on! That said... yeah I think Alain is fast enough to stop her from doubling with the Rapier. He can try to Cavalry Slayer her to seal off one attack and one counter, but Spinning Edge might be better anyway just to ignore counters outright. His physical durability with Noble Guard probably takes things.
Amalia: 209/79 durability (Heavy Guard spam makes her pdur silly), 77% speed, Omega Shatter is 96% (145% with Hawk Eye), Heavy Slash is 73%, Penetrate can backend damage a bit but doesn't really add any.
Amalia vs. Rubicant: Oh dear. No.
Amalia vs. Marcello (DQ8): Amalia would need to OHKO here. Have to imagine I see Marcello as better than 145.
Amalia vs. Sierra: Death.
Amalia vs. Emily: Hawk Eye.
Amalia vs. Celes: Am I willing to see Vanish > Truestrike? I think that's right. Truestrike would trump Image, but not Vanish. Imp renders it moot anyway.
Amalia vs. Yuri: Pretty sure Yuri is tanky enough for this after buffing.
Amalia vs. Nailah: Can tank a Hawk Eye Omega Shatter. Amalia probably shouldn't even attack without Hawk Eye, so like Alain, she's dying to Savage before she gets a chance at a second combat. I guess you could subject Savage's damage boost to Heavy Guard, I definitely don't though.
Amalia vs. Lashiec: Lashiec just misses the OHKO to me. Their speed is very similar! Best case scenario could even give Amalia two turns, and she still has no chance.
Amalia vs. Teepo: 3HKOs, isn't 2HKOed.
Amalia vs. Jessica: Magic Burst.
Amalia vs. Alena: Alena is the Heavy version of Nailah, this isn't good enough.
Amalia vs. Chaz: Explode.
Amalia vs. Artea: Artea has a 3-2 to me, but not an instant double.
Amalia vs. Eirika: Or maybe Eirika is the Heavy version of Nailah. Same story.
Dinah has 45/52 durability and 123% speed. Good evade too, on top of being able to dodge most things that would hit her. 19% damage, or spend 2 AP for 14% damage and poison (with does 30% target MHP). Weakness Hunter can pile an extra 43% but that's 2 valuable PP. Taking her base evade at 70% due to some combination of considering more accurate enemies, difficulty mode differences, and and a slight side-eye to scarves.
Dinah vs. Rubicant: Rubicant has two toys here which help: Fire 2 counters and a doubleact physical. So that's about 9 attacks per combat. If he lands 4 of them he does real damage. He's got a 27% chance of doing that, and 2HKOs Dinah if he does. (He also has a 10% chance of getting 5, which would mean an immediate win.) Dinah might prefer to do less damage, if she only attacks once she only faces 7 attacks, and at that point the chance of Rubi breaking through is 13%... okay, that's not worth it. Anyway Rubicant needs 6 combats to have >50% chance of breaking through the evade twice. Does Dinah kill in six combats? That's (probably) 3.42 PCHP damage she does. I... have memories of calculating Rubicant's HP as just over 3.5. But I haven't yet considered doubleturns, and she should get a few of those in there, and that's probably just enough, for me. Very close match.
Dinah vs. Marcello (DQ8): With only six actions, Marcello only has a 7% chance to land at least four hits, and again he needs to do so twice. Not happening.
Dinah vs. Sierra: I... think? I want to say S2 had magic repel enemies (really hope I'm not conflating with S3 here, but I can remember S2's animation for it in my mind) and Finger of Death / perhaps pure status in general didn't work on them. ... for that matter, does Dinah's evade catch pure status in UO?
Dinah vs. Emily: Okay, eight hits this time, i.e. 24 per combat, that's way too many. Emily will need to sneak a few through but she will, and in the meantime she has evade of her own and poison immunity to get her the time she needs.
Dinah vs. Celes: Nope.
Dinah vs. Yuri: Think some of his stuff had crazy hit numbers, and since he immunes poison and is tanky Dinah can't kill him ever.
Dinah vs. Nailah: Nailah is just too accurate. She's taking Dinah's evade down to like 30. At this point she is probably hitting by her third attack, and OHKOs when she does. That said... Venom Thrust doesn't trigger counters, so if Dinah lands that and three poison ticks she wins? ... no, because she does less than 10% with Venom Thrust (and spending PP on Weakness Hunter makes her die a turn sooner, not to mentino probably DOES trigger a counter).
Dinah vs. Lashiec: Thunder Halberd is ITE.
Dinah vs. Teepo: Uh. Triple Blow may punch through... it's the same odds as Rubicant. Except it doesn't even 2HKO so never mind, that's not working. Teepo needs Howling to turn off evasion. I have no idea if it does or not, and the match hinges on that entirely, so abstain.
Dinah vs. Jessica: If evade doesn't stop Kasnooze, I suppose...
Dinah vs. Alena: Maybe if Alena OHKOed, but needing the second hit is too much.
Dinah vs. Chaz: Explode.
Dinah vs. Artea: See Random, Artea immunes poison and can't die ever. Since he gets more turns (at least to me), sooner or later he'll land the hit he needs, although yes it might take a very, very, very long time.
Dinah vs. Eirika: Unlike Nailah, Eirika probably isn't doubling here, and certainly isn't with the only weapon which OHKOs.
Alain 9-5. A pretty clear Godlike, borderliners only beat him if they spoil him.
Dinah 5-8. I feel like this field is a little light on ITE so she might actually be worse than Amalia, I dunno. Weird dueller, definitely belongs in Heavy though.
Amalia 4-10. Bad speed and magic durability coupled with lots of holes in her immunity list mean she's probably not Godlike, but she is certainly a good Heavy with that big turn 1 ITE damage and physical tanking.
