Phantom Brave: The Lost Hero - Bonus Story: Heroes of the Past

This is the second DLC that gives you two characters and two maps, the other being Walnut and Castille. Like that one, I recommend this one as it's a good value. The story is preposterous for all of them (obviously!) but the characters are both good, and they have unique voices, too.

Sprout is a straight-up fighter (spec: Sword, Dagger, Hammer) who draws enemies and gets a stat boost with most melee weapons. Scarlet is a magic knight (spec: Sword, Dagger, Staff) who is also carrying a level 1 magic sword you can steal. It comes with all three elemental spells so it's a good way to level swords and spells at the same time.

As with the other DLCs, each character has a unique fusion with Marona, and the maps have items that scale to your level on it, so it's a good way to farm those items when you need them. These maps are snow maps, so you get lily of the valley flowers, snowy trees, and black rocks (which you need to upgrade your ship).

Finally, all DLC characters have the "Pirate" title that gives +19% to all stats except speed, which gets +12%. You can swap it out if you don't want it (or give it to someone else) once you get the Old Man NPC.
