Requests are non-combat missions that involve collecting specific materials and delivering them to various NPCs. These are crucial for unlocking new services, expanding shops, and gaining permanent stat boosts for your characters. Requests are found on the world map, often marked with a scroll icon. The required materials can be obtained from combat missions, enemy drops, or purchased from merchants.
It's a good practice to periodically check your available requests and see if you have the necessary materials. Completing requests can unlock new combos, increase character health, or provide access to better weapon fusion options. Prioritize requests that offer significant character upgrades or unlock new features that benefit your entire roster.
