1 Vs 18 Challenge (Knight Commander)
So there's a few things that make this particular challenge feasible in this case.
First of all, though Cursed Weapons are generally viewed as as one colossal waste of time to get, they can still be really useful in the hands of someone with enough damage bonuses to not need any help breaking through most damage thresholds. In this case, because Ozma could reliably use her innate high damage, sword and anatomy bonuses to break through any armor the other team had, she could easily do absurd amounts of damage with Strengthen and Instill Ice applied. Although her spear skill was at it's lowest, the buffs still allowed her to break through and do some reasonable damage with it. If You're wondering why I didn't just give her two swords, she has a tendency to hit a lot of crits, which can only be followed up by a spear if using two weapons.
Secondly, the Knight Commander class has the semi-unique ability to both avoid one magic attack per round, as well as get high enough dodge from a combination of sword skill, stat buffs, and equipment bonuses to dodge or tank anything coming her way physically. She actually has enough armor to completely plink crossbow bolts, as You can see. Also, due to intercession, I believe some of the Shackle hits from Infernal Kiss bounced off. I'm not sure on that one, but in general, I was using intercession and Bloody Mary to keep the enemy team occupied, and hopefully keeping them from doing anything more useful, such as healing.
Thirdly, I put her in a position where she would only realistically have to deal with a few inaccurate units at once, using the few available openings at the start to take out as many familiars, rogues, warriors, and terror knights as possible, in order to not have to worry about using parry to deflect guaranteed hits, or getting screwed over by a Frighten hit.
If You're wondering if this would work in the original...it would, and it would actually be a lot easier on account of the stat system being utterly cheesable. Also, Rending Gale ia basically a one-shot move for her.
Also, if You haven't played the mod before, You may notice that there's a lot of new and interesting things going on! That's the amazing One Vision mod, one massive overhaul that's still getting updates, and really just makes the game click.
Updated for 05/08/2018: Since the Cursed Spear was changed to a 2h weapon again, this strategy is better done with the Cursed Sword and Cursed Dagger, though a Bashing Shield or Reflective Shield may be better in that second spot. Personally I just love the idea of hitting something 6 times.
