The Mappa Mare is a free 4-star Catalyst available to all players. There isn’t any special unlock requirement, but crafting the weapon does require some grinding because the weapon requires a Northlander Catalyst Billet, only available through weekly boss drops or as quest/exploration rewards.

Once you obtain a Northlander Catalyst Billet, you can use it to forge either the Prototype Amber or Mappa Mare. Mappa Mare is a niche weapon that is mostly outclassed by other options, and not many characters can use this one.

Is the Mappa Mare any good?

The Mappa Mare is a niche weapon that is outclassed by a 3-star option, the Magic Guide. Additionally, only one Catalyst user really benefits from Elemental Mastery to this extent, and that’s Sucrose.

Sucrose prefers two Catalysts that are easily obtainable, the 3-star Magic Guide and the 4-star Sacrificial Fragments. Both are Catalysts that can be obtained from summons, but the Magic Guide is common, and getting multiple Sacrificial Fragments is not impossible.
