Huh. Culise, why'd you cancel your attack if you have such good odds?
I would need Sharpness. Without it, I only have a 67% chance to hit. The biggest concern is that it basically focuses both of our Sages on one attack; the alternative plan would be to have Raquel and Edwin both use Sharpness on two people, who then get two attacks. I'm still gaming through those possibilities.
EDIT:
OK, of our available players, Tantallos, Edwin, and Riven are out of range, leaving Charlotte and Gregor as our available alternatives to Raquel. Charlotte can get a guaranteed hit (113%) with Sharpness and Gregor, even through Daunt, but can at most do 24 damage with a 44% chance at crit through her Killer Bow (drat pillars and their lack of defensive boosts). Gregor also is forced to go up against his strong protection stat (DEF), and also has to worry about being in range. That said, he can get a guaranteed hit with Sharpness and Charlotte, along with Sworn Protector triggering. He would do 12 damage or 36 on a crit (46% chance), then take the counter-attack, which will be significant but not devastating in spite of being doubled. Dag and Mannan are our alternatives, but putting Sharpness on them creates a situation where Aaron gets a free move. He didn't actually move at all last turn, but I would not bet on that continuing.
Basically, Raquel can hurt him (29 damage) and has a coin-flip's chance at one-shotting him in return for two actions (Edwin + Raquel); that also leaves our others free to make less-accurate follow-through attacks. On the flip side, we can take four actions (Edwin + Raquel + Charlotte + Gregor) to go for 20 damage with a 20% chance of putting him in negatives.
...hmmm. Does that summary seem accurate? It's fundamentally reliant on my maths not being completely wrong, which is a bit of a fool's bet. And that's my last edit, hopefully. ^_^
OK, one last edit. Raquel does have a chance at missing altogether, and given how entertainingly the dice can dance, I wouldn't rule it out. ^_^
