Okay, let's figure out what we're doing with this turn.
The mini bosses are coming up from the west, so we have one more turn before they're on us. The General will be a turn late either way I think, but I can't think of a way to tear through all of the fliers in that time, so I think we're between a rock and a hard place either way.
If Seyena picks me up and then sets me on 19,12, and then someone (Alex, probably) heals me, I can give Charisma to all three of our front-liners this turn. That'd also give Olison support to maybe smash another Why-vern. I'd suggest one of the ones with higher health. C only has 5 hit points, and I'm fairly certain Alexander can do at least that on a counter.
If Sal can land it, he might want to kill Why-vern C.
EDIT: The minibosses themselves.
Silverio would Destroy Alexander, barring Great Shieldhax. He also has top-tier evade, so even though Valor could crit him to death in theory, I only have a possible 58 percent chance to actually hit him with my Killing Edge. And my crit chance would be 81, so it's a lot further from a sure thing than we worked from last turn.
With his Killer Lance, Salvatore is probably our best bet against Silverio, as he only takes 2 damage per hit from Silverio (If he's being supported by Alexander anyway), meaning a maximum of 12 hp lost in a fight with him. He does 20 Damage with a 43 crit chance, but a piddly 45% chance to hit. Still, he can drop him in one turn, and more safely than Valor can do so by a wide margin.
I think we determined that Gleipnitz is more or less impervious to most of our attacks. We should probably leave him for last, surround him with physical fighters, and let our NPC's magi-murder them. We could chip damage him all day long, but that'd be tedious for everyone.
June is going to be a bitch and a half. Benediction will allow her to either evade one attack entirely, or autocrit one person. Also, she'll survive one attack that would drop her with 1 hp, which will activate her Resolve, driving her Speed up to 31(!) and her Skill to 36(!?!), making her even more difficult to hit and kill. We may have to rely on Seyena to deal the final blow. Waiting three rounds or so for her to come out of Resolve range from her ring is probably not an option.
Edit: What level is Tiron? If he's 10 or better, Sharpness would give Salvatore or Valor the edge we need against Silverio.
