Well, you get 5 swordmasters, two of which start in the class. Of said 2, Eyvel is useful when you have her, but is kinda deadweight once you get her back in chapter 24x, while the other, Shannam, is a joke character whose only use is buying things at a discount with his bargain skill. Shiva is probably the best of them, having the best availability, a PCC of 4, Sol, and oddly high Str and Def growths for his class(45% and 30% respectively), and while his speed growth is pretty low for a myrm(35%), it's offset by his high base(12) and Thracia's low caps. Mareeta is very good as well, despite joining kinda underleveled, she has very good offensive growths(though her defense is pretty bad), luna and eventually astra, a PCC of 5, and a personal weapon that has a brave effect, 20% crit, and the nihil skill. Troude is okay, but very unremarkable compared to Shiva and Mareeta.
