Item Storage can be accessed from the upper left corner of your menu.
Once you are in your Item Storage, there is a navigation bar at the top of the screen, where you can select the various categories of items.
Space in your Item Storage is limited, so you will want to make sure to check in periodically and clear out any items that you do not need to hold onto. Additional space in the Item Storage can be purchased by using Diamonds.
This is where you will find all of the ingredients that you have earned from quests and from farming Free Stages. Additional information about how to farm for Ingredients in Free Stages can be found here.
This section is where all of the completed recipes can be found. You can use these either as gifts to increase Hero Affinity or to utilize boosts for combat. Cooking can be done in the Tavern by speaking with Ban and is a daily task to perform to earn free rewards. A table of all available recipes and their necessary ingredients can be found here.
If you are running out of Item Storage space, this is the easiest place to find items that you can clear out. In this section, you will find one-time use items, such as tickets to use in the store, stamina potions, dungeon keys, equipment draw boxes, and awakening material boxes. Make sure to check here periodically to open up your boxes to help you grow and also keep your inventory clean.
A listing of all 1-Use items can be found here.
This section contains all items that don’t fit into any of the previous categories and aren’t equipment. Primarily in this section you will find treasure chests, giftable items that can be gifted for Affection, and any applicable event items. A listing of all non-event Misc items can be found here.
If there is an event going on that requires spending spin coins or exchange tokens, make sure you check here to see how many you have on hand. Once the events are over, any remaining event items on-hand can be sold for silver.
If you want to save time and sell multiple items at the same time, click the Sell Multiple button in the upper right-hand corner.
Equipment inventory is separate from the rest of the items inventory that is listed above. If you run out of space in your Equipment inventory, you can either sell the Equipment for Gold or salvage them for materials with Diane in your Tavern. For more information on what Equipment you should prioritize holding, see the Equipment guide.
