First stop, Delmud.
Here's a look at chapter 21 Tanya, in range of her Othin support. I assume she got the Neir and Hezul scrolls for ~60% of her levelups between levels 7 and 20, and Dain and Hezul 60% for the remainder. Effectively, I just turned +10% growths into +6% growths, and so on. I don't think the community has agreed on just how much people can be assumed to have scrolls, so I'm eyeballing things here.
Tanya 20/5, in range of Othin support:
38 hp
9 def
5 mag
Steel bow: 25 mt, 118(+leadership) acc, 15 AS, 58(+leadership) eva, 30 crit
Silver bow: 30 mt, 128(+leadership) acc, 18 AS, 64(+leadership) eva, 30 crit
Killer bow: 26 mt, 128(+leadership) acc, 18 AS, 64(+leadership) eva, 60 crit
Brave bow: 29 mt, 153(+leadership) acc, 17 AS, 62(+leadership) eva, 50 crit
Tanya has 2 PCC, so even with a 0 crit weapon, she has a 90% chance of critting at least once over two attacks, which kills basically anything. And then of course her only real competition for the brave bow is Xavier, who has plenty of other options (enough bld to make the master bow plausible, if nothing else).
Here's base level Delmud, in range of Nanna support (Nanna's charisma factored in):
36 hp
9 def (8 unmounted)
5 mag
Steel sword: 20 mt, 116(+leadership) acc, 12 AS, 51(+leadership) eva, 22 crit
Master sword: 25 mt, 111(+leadership) acc, 8 AS, 43(+leadership) eva, 32 crit
Beo sword: 27 mt, 121(+leadership) acc, 10 AS, 47(+leadership) eva, 52 crit
5 PCC, so he's always critting anything he doubles. And if that's ever in doubt, the Beo sword grants wrath and ambush. He also has charisma as a personal skill.
Defensively, Tanya wins. Higher hp, tied defense and magic, higher evasion, even with Delmud always in range of Nanna's charisma, which Tanya can take advantage of too. The difference isn't huge, but the difference is there, and is a point in Tanya's favor.
Player phase offense is identical. They both kill whatever they target. Tanya doesn't have to take a counter from a significant number of enemies, though, while Delmud does. This drives Delmud's defense down more; he has to rely on a 25% crit or a heal staff to avoid going into the enemy phase with less than full hp.
So, now some points in Delmud's favor. He has 2 more move by this point (Tanya's move rounds up to 8 at this level), and of course has canto. However, out of the remaining chapters, only 21, 22, and 23 are outdoor chapters. 21x is usually just raided for treasure and then left without combat, but that leaves 24, 24x, and 2final as indoor chapters--a full half of Delmud's availibility. In indoor chapters, he loses canto, and actually has _less_ movement than Tanya.
Delmud also has enemy-phase offense. Provided he can counter the enemy, he insta-blicks them with an ambush critical 25% of the time, and is pretty much guaranteed to kill them with his pursuit attack. Taking a look at chapter 22 enemies, though, he's 3HKOed even if you give him a few levels, and the Gelpritter occasionally 2HKOs him. Factoring in his ambush crits, he can afford to face 2-3 enemies before you're putting him in a tactically unsound position. This is no challenge in chapters 21, 24, and final, but severely limits his enemy phase offense in chapters 22, 23 and 24x--half his availibility.
Tanya has the same durability concerns, but we all already know archers have bad enemy phases--I merely wanted to show Delmud's enemy phase isn't so hot either.
Delmud's final advantage is charisma. No real explanation is needed.
So, during the time Delmud is present, he has over Tanya charisma, a mediocre (as opposed to terrible) enemy phase, and (half the time) movement. Tanya has over him a slight durability lead, and movement the other half the time.
A Delmud win? Maybe. But if so, a slight one. And here's the kicker-- Tanya has 20 more chapters of availibility. The only way this is not a blowout in Tanya's favor is if she actually has negative utility while training her. I'd be _very_ happy to argue against anyone who thinks that, but for now I'll let this argument rest.
