FE13: Lunatic+ ch2

This one is pretty tough.
Normally on regular Lunatic I like to pair Virion into Robin and attack the mercenary at the start, then finish them off with Frederick. This is usually safe since the barbarian leaves base Robin at 1HP and prevents them from taking more hits, while also luring the remaining enemies towards frederick. You're also able to let fred pick up the elixir if you forgot to do that last chapter, which is neat. With Luna+ being a thing however makes this strat unviable, however.
I instead went with an opening I sorta copied from hiiyapow where you move Fred far northeast with Vaike, baiting more enemies but being at a higher risk of death. From there I mostly just improvised, though I basically needed every attack to land. After the bottom half was done the rest of the map was pretty much a cakewalk.
