I brought in the new year playing Fire Emblem: Awakening (which I've been obsessed with after finally getting it working on an emulator). I'd been struggling with lunatic mode but I figured out I can just feed Robin because of the XP boost and then use her to carry the team. Changed her to Pegasus Knight and then Dark Flier and now I can just swoop in and one-shot any enemy and she's over-levelled enough that the enemies won't prioritize her, and if they do, she dodges everything and has enough HP to survive a bow to the face.

The early levels were very challenging and I had to heavily abuse save states but once I got rolling it's been a lot smoother. The two cavaliers you start with literally can't survive a single hit starting out. Since everyone's so vulnerable, you just have to get one unit good asap to avoid relying on your Jagen.
