Consumables: These are single-use items that provide immediate benefits, such as restoring HP or MP, curing status ailments, or temporarily boosting stats. Stock up on several consumables before heading into dungeons or boss fights. You can purchase them from convenience stores, pharmacies, or find them in treasure chests.
- Healing Items: Bento Boxes, Hawaiian Punch, First Aid Kits.
- MP Recovery: Energy Drinks, Coffee.
- Status Cures: Antidotes, Eye Drops, Refreshing Towels.
- Stat Boosters: Attack Boosters, Defense Boosters (temporary).
Key Items: These are unique items essential for story progression, unlocking new areas, or completing specific quests. They are usually acquired automatically through main story progression or as rewards for substories. Key items do not take up inventory space and cannot be sold.
Always keep a healthy stock of healing and MP recovery items. Don't be afraid to use them during combat; it's better to use an item than to have a party member knocked out. Key items are automatically managed, so you don't need to worry about them.
