This Langrisser M map event can be kind of annoying when you first unlock it, because it seems like a big time-consuming brawl. The quick clear strategies involve blitzing the first wave of enemies with AoEs to take them out on the first turn, but what if you can't do that?
The keys to the fight are rushing the middle and drawing aggro from the top enemies ASAP. If you don't go to the left or right, none of those extra enemies will spawn. And if the top reinforcements can attack you, they won't bother going for the chest anymore.
Hopefully this approach will make it a bit easier for you to get some sweet SSR equipment from this map. Never let one of these events slip by unconquered!
