Get out of here Id~Purpose~ and End of All. Twilight of the Gods is my new favorite final map theme in Fire Emblem:
Seriously, THIS is how you compose a final boss track!
What I really loved about this map is that when you first select your units when the battle starts, they each have something to say either to Jedah or Duma, or they talk about how the continent shouldn't be ruled by gods. All of them have a unique way of how they say it, and they really pep you into the battle. My favorite has to be Conrad's: "Duma... O ancient benefactor. Consider this is an act of mercy. A great god is deserving of a great and glorious end." Sounds pretty poetic. Forsyth, Python, Mathilda, Saber, Mae, and Sonya's quotes were awesome too.
My team for this battle: Alm, Celica, Lukas, Forsyth, Python, Mathilda, Delthea, Clair, Clive, Dread Fighter!Gray, Silque, Tatiana, Saber, Mae, Sonya, Dread Fighter!Atlas, Leon, Est, Catria, and Conrad.
The battle was pretty difficult even on Normal Classic, but it was still duable. Lukas, Forsyth, and Clive handled the two Dread Fighters on the left side of the map. Delthea got a KO on the Gold Knight, and then Silque (protected by her Invoke units) warped her away. Clair and most of Celica's units took care of the initial chunk of Moghalls. When it finally came time to take out Jedah, I had to rely on Leon to stall out the curse. Jedah even scored a crit on him at one point, so I had to use Mila's Turnwheel to reverse that. Once Alms units caught up, Python, Delthea, and even Celica helped in stalling out the Curse. It was Mathilda who ultimately killed Jedah. She was the most reliable in getting the job done.
I didn't have any trouble taking out the two Bow Knights, but it was in the second half of the battle dealing with the Medusa Arcanist, Hestia, and Marla when it got difficult. Conrad died at one point because I accidentally put him in range of Medusa and a Witch followed up with a kill, so Mila's Turnwheel came to the Rescue again. Luckily, he took everything else like a champ. Python and Leon worked together to take out Hestia. When it was time to take out the Medusa!Arcanist, I had Python use his Silver Bow art to cancel the Arcanist's attack so that I could safely follow up with Leon and Set for the kill. The Invoke Dread Fighters eventually killed Marla as well. Tatiana was also very clutch in dealing with the Earthquakes.
That left only Duma. It took a while to take him down. Invoke Dread Fighters and Pegasus Knights, as well as Python, Leon, and Set did most of the damaging. Even Catria tried to lower his HP, but she got KOd in the enemy phase when I expected him to go after one of my Invoke units. Oh well, at least Mila's Turnwheel saved the day. Once his HP was low enough to the point no one could attack him but Alm, I had to heal him with Celica and Silque every turn because he wasn't landing the crit to finish Duma off. After about 3-4 turns, Alm finally got the kill on Duma.
In all, the battle was difficult and got annoying at times, especially when dealing with Duma, but I'd say this is up there for one of my favorite final maps of the FE games played, tied with Revelation's end-game map
