Fire Emblem Engage has several Paralogues, and the last two won’t unlock until you are near the end of the game. This includes the last Emblem Paralogue, which belongs to Marth, a tough opponent who can be rather hard to deal with on the battlefield. The guide below goes over how to defeat Marth in The Hero King Paralogue without losing any of your units and how to get all the treasure on The Broken Castle map.

How to Unlock Marth’s Paralogue: The Hero King in Fire Emblem Engage¶

You will unlock Marth’s Paralogue, The Hero King, after you beat Chapter 22. Be warned, though, this is the last Emblem Paralogue, and it’s a difficult one.

How to Defeat Marth at The Broken Castle¶

This is the very last Emblem you will need to face in battle, and Marth isn’t going to make things easy on you. To survive this map and get all the treasure, you are going to need to have a good army built. The strategy here is to bring in magic users for the armored units, so Lindon, Pandreo, Ivy, and Hortensia are all good choices. You will want to bring Seadall and Byleth for extra movement, as well as Corrin to use her Torrential Roar ability to tame the Martial Mages.

In addition to this, units that can warp, like Celica can help you easily maneuver around the map. Archers, like Alcryst, can also help you to hit Marth from a distance. If you don’t want to bring a weaker unit like Alcryst, then using Lyn is a good idea. When you start the battle, you will notice that this map is rather sectioned off, making it hard to move around for anyone but your flyers. You should also note that Marth is in a sealed room, he either has to open the door himself or you will need to break it down.

You can either choose to go directly for Marth or go around the map collecting the treasure. The best way to get the treasure is to let the Thieves grab it, then kill them to obtain it. If you don’t want to do this, then you can warp to the locations for a quick job. Once you get the treasure, you will need to head toward Marth.

Once there, either use a ranged attack to get him to start moving out, or you will have to break the door down with your units. There is a General you will need to defeat twice, as he has a revival stone. A Sage and Martial Master are also present that you will want to quickly wipe out to keep him from helping Marth.

When you face these two enemies, Marth will begin to move. His Loadstar Rush is a powerful attack, so try to keep your distance from him to avoid it. Depending on your playstyle, you can either enter the room with Marth, which is a bit more dangerous or let him exit, which is the ideal scenario. Marth is a fast close, range attacker, so try to keep a safe distance and hit him with ranged attacks. If you do want to get up close and personal, then use Emblems to quickly cut down his health bar.
