Re: Sengoku Rance
so which commanders do you have, its hard to offer advice with so little to go on
if you have any people in prison you might be able to recruit them for that little bit of extra damage, then dismiss them later if you're short on national power
just remember that when you fight xavier, its important that rance stays alive (you basically auto-lose if he dies) so put him in the back row if you dont have a miko to keep healing or some dude to guard-shikigami on rance (and even then its still safer to put rance in the back)
if you really need rance's damage, put him up front along with a foot soldier and make sure to keep guard up so xavier cant oneshot rance
another hint i can give you is that if you switch out a character in the back row, it will usually be sil who comes to replace them, who can heal rance for alot of hp every time and also restores one action point (allowing you to spam rance attack)
also, if you have any spare tacticians, put them in the field at the start (as they will buff random people at the start of battle, similiar to casting battle strategy) and swap them out with suzume (due to her speed she will usually not lose a turn after swapping)
personally, i did only 2 dungeons and used no special weapons, went in there with:
Rance (duh)
Sil (duh)
Suzume (again, duh)
Ranmaru
Shibata katsui (or w/e his name is spelled)
Yamamoto isoroku
Uruza (important!)
Senhime
these were all the people i needed, uruza will shoot xavier to scrapnel in a few hits, combined with rance and suzume attacking, ranmaru dealing a little damage on the side, sil healing rance and shibata guarding the front line (and once he got murdered senhime took over)
in addition to these guys you can simply use alot of trash commanders from your prison if you run into trouble (recruit anything you can before doing the event)
hope it helps!
