skill-wise this banner is a big skip for me. shannan's art work looks really cool and will probably be the target of my free pull, but another strong sword infantry is pretty forgettable. it's also weird his special, which does the exact same thing as regnal astra, doesnt have the specification it can't be inherited but regnal astra does. i doubt imperial astra will be inheritable tho, since it isnt weaker than regnal astra. they probably just wanted to avoid confusion since regnal astra has appeared on more than one unit now, and they might have worried people will think it is inheitable.
altena is the obvious demote here, with all of her skills being pretty unwanted and easily attainable from grails or 3/4* units, but her weapon looks fun so i might promote her if she does demote. cid is cool but i think lewyn's tome is stronger, and has special spiral. finally, loli Arya Larcei. same story as shannan, i like her art and she's got some cool stuff in her kit, but the sword infanry class is so stuffed i've already got 3 other fast sword units with prfs in my barracks i could build instead. real shame theres no direct demote on this banner, it was looking like a permanent thing so i wonder why they didn't this time round.
