So I've cleared Conquest Lunatic/Classic with no deaths (no, Xander's tragic death by RNG in Endgame doesn't count)
Thoughts on characters:
Corrin - Even with a def bane, he could tank quite well with a dragonstone. Funniest moment was in Chapter 25, where Ryoma had <10% hit rate on him, and he could double Ryoma with base speed.
Felicia - Useful as a staffbot. Damage potential is null until flame shuriken or reclass into strategist.
Gunter - Jeigan. Benched as usual.
Silas - I liked him, and wanted to use him. But 9 speed at level 14 was the last straw.
Elise - Staffbot + aurabot + glass cannon. Also, mother of my favourite unit.
Arthur - I'd have used him, if not for the fact that he couldn't hit the broad side of a barn. I'll give him a try next playthrough.
Effie - What can I say? She started oneshotting enemies since the archers in Chapter 10. Promoted her to Great Knight, and she capped Str, Luck and speed.
Niles - Best utility unit + shuriken breaker/10
Odin - Eldritch Smackdown! Used him as a swordmaster. Was not disappointed.
Nyx - Benched. At least Elise was a good staffbot.
Azura - Azura/10. Almost gave me a heart attack when I accidentally left her in range of a kitsune in Chapter 19. Luckily she somehow had enough HP to survive the hit.
Camilla - Hit level cap in Chapter 24. That's how good she was <3
Beruka - Benched her because I didn't have enough deployment slots. Still, she seems like she'd be good. Using her in my next playthrough.
Selena - Pretty good once her strength starts to pick up. Her personal skill was totally made for killer weapon attack stance shenanigans.
Kaze - Mage slayer/10
Laslow - Turned out to be Lafast. Equipped him with a killing edge for hilarity. Also, master ninja with Sol is <3
Peri - Once again, benched due to deployment slots. Offense seems good, although she lacks bulk.
Benny - Would make a solid general, but I already have Effie + incoming Xander. Benched.
Charlotte - Pair up fodder/10
Leo - He's probably good, but once again: deployment slots. Should give him a try sometime, preferably reclassed to sorcerer because I don't really like dark knight.
Keaton - I NEED MORE DEPLOYMENT SLOTS! Seriously, stop giving me units that look like they'd be useful when I've already filled up the given slots.
Jakob - I forgot he even existed.
Xander - Totally worth 2 deployment slots. Most problems were solvable by throwing Xander at them. Should probably have reclassed him for Sol just to see how broken that would be.
Shura - Filthy Corrinsexual Actually his stats don't look half bad. But I already have Niles, so to the bench it is.
Children characters were all recruited after Chapter 20.
Elise!Ophelia - Goddess. Nuking everything out of existence since Chapter 21. Next playthrough I'm making a +Mag Diviner female Corrin just to see how much she can break the game.
Selena!Soleil - Laslow x Selena may not have been the best pairing. Had nothing much in terms of skill inheritance. Still, Soleil was pretty decent. Stats were good all around.
Felicia!Nina - Niles x Felicia supports were hilarious. The resultant Nina's combat abilities turned out to be hilariously bad. At least she had decent utility as a pass staffer.
Effie!Midori - Probably not an optimal pairing for Midori, but her strength did turn out to be pretty ridiculous.
Memorable chapters:
Chapter 10 - One of my favourites. I love defense maps.
Chapter 19 - Was annoying until I figured out how the gimmick with the foxes worked.
Chapter 20 - Again, annoying until I figured out the wind gimmick. ​Hayato's hexing rod pissed me off, so I sent Camilla in with the dual club to delete him.
Chapter 21 - Stoneborn with high HP, defense and wary fighter? Meet Ophelia Dusk, goddess of destruction. Also, why is Golembane so useless?
Chapter 23 - And now I have a grudge against Hinata. That avoid is just unfair.
Chapter 25 - To hell with stacking debuffs and 3 range lunge. Time to break out the freeze and entrap staves. Also, I had to make sure Corrin didn't accidentally kill Ryoma when attacking.
Chapter 26 - WHAT THE ACTUAL FUCK. I'm just going to avoid that infinite hexing rod and ignore the room with the faceless.
Endgame - What a bitch. How does anyone not cheese it with rescue staves? It was the only time I regretted choosing +Spd/-Def Swordmaster. Luckily I had reclassed for Life or Death and grabbed Trample from waifu!Camilla. With capped strength from stat boosters + tonics + rallies + S rank sword from arms scroll, I barely hit the benchmark for a reliable ORKO on Takumi. And Corrin went on to activate Dragon Fang for overkill…
EDIT: Forgot Jakob.
