While some Fire Emblem titles are structured in a way don't allow for grinding, Fire Emblem Engage will let you earn as much EXP and money as you want. So if you are looking to get some extra cash, here's how.
The key to grinding in Fire Emblem Engage is through fighting Skirmish battles. Skirmishes will start showing up after Chapter 6: The Stolen Ring. While these additional battles are completely optional and don't move the story at all, you can fight as many of these as you desire to grind money, EXP, Support ranks, Bond ranks, Bond Fragments, and other various rewards.

Fire Emblem Engage How to Respawn Skirmishes
But once you've fought several Skirmishes in a row and cleared the map, you might be wondering how to respawn more skirmish battles so you can continue your grinding spree.
Skirmishes primarily respawn after enough real-world time has passed. So if you wait long enough, more Skirmishes will appear, eventually. But what if you want to fight another Skirmish now?
The answer is simple. The easiest way to respawn skirmishes on the world map is to manually change your Nintendo Switch clock. You don't even have to close your game to do this.
Simply press the Home button on your Switch to return to the mains system menu, head to Settings->System->Date and Time, then manually set your clock an hour or two ahead of the current time, and jump back into the Fire Emblem Engage. The next time you enter the world map, more Skirmishes should show up immediately. Simply repeat this process whenever you need more Skirmishes to appear.
There are four types of skirmish battles that can show up at any time.
- Skirmish: This is simply a regular skirmish battle that take place at most locations on the world map. You can gain EXP, character Support ranks, and Emblem Bond rank during the battle. After battle you can earn Bond Fragments, adopt animals, and various ingredient items while exploring the battlefield.
- Training: This is a slightly different type of Skirmish battle that takes place at select locations on the map, usually allied castle locations. These battles work nearly identically to regular skirmishes, except you'll earn a money reward after clearing the map, plus a bonus 50 EXP to every unit that participated in the battle.
- Silver Corrupted: This is like a regular Skirmish battle, except some enemy units will be replaced with special 'Silver Corrupted' enemies, which reward more EXP when defeated.
- Gold Corrupted: This is like a regular Skirmish battle, except some enemy units will be replaced with special 'Gold Corrupted' enemies, which drop money when defeated.
