As a update to my progress, I have beaten Oil and Water, The forgotten, Ocean View, Sword and Shield of Seiros, and Rumored Nupitals and claimed all of the rewards.
Replying to Glennstavos, I have indeed cleared the paralogue with the Thyrsis.
To reply to some people already, I've recruited everybody Black Eagles and Blue lions Students, the Seiros units up to Alois, and all of the Wolves.
I might be trying to do Falling Short of Heaven and a Cursed Relic once I get into the Advanced classes on most of my units like Felix and Constance.
True Chivalry I can try and do once Felix is a Swordmaster because it's not as simple to play than it was on Hard Mode. I can see the Shield being something that could come in clutch later on.
Dividing the World is something I might try a few times pre-timeskip, but if it doesn't work, then I'll save it for post-timeskip.
Secret Merchant is available (for me) before post-timeskip, but it is a difficult one on Maddening.
I think I could try it out, but I haven't invested in Anna as much. I may skip out on it. If anyone wants to inform me on the rewards and how good are the battalions from that level, feel free to do so!
Feel free to give me more feedback! I'd greatly appreciate it!
