Grinding for EXP and Gold is a vital strategy in Fire Emblem: Fortune's Weave, especially for players who want to ensure their units are adequately prepared for the game's increasingly difficult challenges. Skirmishes are your primary avenue for this. These randomized battles appear on the world map and offer a consistent stream of enemies to defeat, thereby earning experience points for your units and gold for your coffers. It's advisable to engage in skirmishes whenever they appear, particularly if your units are lagging behind in level compared to the main story's progression. Prioritize using units that need the most experience, and ensure you have a balanced army to handle various enemy types.

To maximize your EXP and Gold gains, consider the following strategies. Firstly, always aim to defeat all enemies in a skirmish; this yields the highest rewards. Secondly, utilize units that have the "Rally" skills or other support abilities to boost the experience gain of your allies. Thirdly, if you're struggling to defeat enemies quickly, consider using units with high damage output or effective weapon types against the current enemy composition. For gold, remember that selling unwanted items or equipment can supplement your earnings. Don't neglect the benefits of the Arena, which also provides a steady income of gold and valuable items through combat.
