Hi, everyone. I'd like to thank everyone who commented on my previous post and give an update on how I decided to build my knights, with a little explanation of the thought process behind each unit. Starting with:
Agrias: At first I was going to give summons to Lavian and leave her with geomancy. Then I realized she has the most HP of the whole team and enough MP to cast Golem even without a robe. I also gave her Moogle, Lich and Sylph for varied support capabilities.
Mustadio: Big thanks to Zazieranyday for recommending the companion app. Not a lot of knight builds there, but the Gun Knight one for mustadio immediatly caught my interest, specially since a lot of comment suggested a knight with guns. A fun fact I found out about machinist in the TLW remix mod is that the snipe secondary has innate equip guns built in, freeing up the support skill slot for stuff like concentrate and attack up. At some point I might just ditch the shield and pick dual wielding, we'll see.
Joanna: This build was heavily inspired on TitaniumLegman's Paladin build, so not much to say besides how easy it is to set up. I gave her abandon for now, but I might switch back to weapon guard once I get a defender. Hard to improve perfection.
Alicia: Huge thanks to Nyzer for recommending an archer/knight hybrid for disruption. Also to adratlas and Major-Corner for recommending mixing aim and dual wield with arts of war, I'm a bit surprised those three synergize so well. I'm often tempted to just switch her to ninja for extra speed or archer for dual crossbow action, but I already have another unit for that.
Lavian: By far the build I've been most indecisive about, since I already have a dedicated Mystic. I left her with equip spear and martial arts for a decent while, but since so many people recommended a knight with mystic arts, I decided to keep her like that for now. I'm still considering giving her a spear or doublehand later along the line, though. Or maybe I'll turn her into a tanky barehanded knight, who knows! Btw, thanks to LancerGreen for reminding me of swiftcast, I still gotta train that on Agrias.
Anyway, I'm off to raid a church library and beat up some zealots. Wish me Luck!
