As like many video games currently on the market, Fire Emblem Echoes also has a number of Downloadable Content (DLC) that a player can purchase to further aid them in the game. Most of the DLC Packages will award a player with rare items and even some experience too, and they usually cost, individually, between $1.99-3.99. There are three DLCs that player can get for absolutely nothing called Mila's Bounty, Mila's Bounty 2 and Mila's Bounty 3.
After purchasing a DLC, a player will need to know where to look to access it. Once you reached the point where Alm can access the World Map, simply go to the menu from said map, find the Connect option, and then choose Manage DLC. From there, you will have the option to play and/or purchase a DLC. Buying the Season Pass will give you a great discount compared to buying them individually, but since you won't get a refund after any purchase, you should decide up front whether you want all the content or just a few DLC.
