is Devilsknife or Devilstail better for beating The Knight? And is it any worth it to get the Puppet Scarf and make Ralsei a damage dealer or is it better to just keep Dealmaker on Susie?

Stat-wise, magic is very useful for training Susie's healing, but I went with the Jevilstail and the Dealmaker.

Devilsknife, Dealmaker, Shadow Mantle on Susie.
Bounce Blade, Chainmail, Tenna Tie on Kris
Fiber Scarf, Tension Bow, Blue Ribbon on Ralsei
Susie is the only one who's doing damage against the Knight, so keeping her alive and maximizing Rude Busters is the best way to get through the fight. Ralsei is the most useless, Blue Ribbon is only on him so you don't need to waste revive items or TP if Kris goes down since it boosts healing items.
I haven't checked to see if Noelle's watch actually does anything useful, I'm convinced the graze time bonus is a placebo. Avoid the graze area ribbons because they lower TP gain. Tension Bow gives the same as two Lode Stones so only use the latter if you don't have the former.
