Arena Battles and Rewards in Fire Emblem: Fortune's Weave offer a dynamic way to earn gold, experience, and valuable items outside of the main story and skirmishes. Located within your My Castle, the Arena allows you to pit your units against a series of AI-controlled opponents in tactical battles. Each victory grants you a reward, which can range from gold and experience points to rare weapons and accessories. The difficulty of the opponents scales, providing a consistent challenge for units of varying levels. It's an excellent place to test your army's strength and to gain a steady income of resources.
To maximize your gains from the Arena, it's advisable to send units that are well-balanced in terms of offense and defense. Pay attention to the weapon triangle and enemy types to ensure your units have a favorable matchup. Winning consecutive battles often yields better rewards, so try to maintain a strong winning streak. Regularly check the available rewards for each tier of the Arena; some might offer items or weapons that are particularly useful for your current party composition or playstyle. Don't underestimate the value of the Arena for quickly boosting your gold reserves and acquiring essential equipment for your army.
