The portable item system from "SAMURAI WARRIORS 3" returns for this title. You can customize your items to each stage or difficulty level by choosing ones that focus on the area of your greatest need. Load up on Health boost items for a particularly difficult stage, or use those that boost your Attack strength for a stage you need to clear quickly.
|Dango||：Restores the Health of you and any surrounding allies.|
|Cup of Vitality:||：Restores your Musou Gauge.|

These are materials required to upgrade your weapons. There are four categories (red, green, blue and yellow) and each of them have two types: normal (like Garnets) and rare (like Rubies), making for a total of 8 different kinds of gems. You can obtain gems by defeating enemies or by melting down unneeded weapons.
You can use gems to upgrade the weapons that you obtain in battle. Each weapon can have up to 8 Skills that fall under 4 different categories, and the cost in gems to upgrade the weapon differ by category. All Skills have a current Skill Level, as well as the maximum Skill Level they can obtain.
Additionally, some weapons have some Skills that are locked. These Skills require rare gems from their specific category in order to be made available. These locked Skills are usually more powerful than unlocked Skills.
You can take weapons from one character and reforge them so that they can be equipped by another character. This feature is useful for developing newly available characters or when you wish to manage the number of weapons you have in inventory. However, the Skills associated with the weapon during a reforge will revert to Level 1, meaning that you will need to upgrade the weapon all over again in order to strengthen it.
You are able to exchange gems from one kind to another, making it possible for you to obtain the gems you need to upgrade your weapons. In order to obtain a normal gem (such as a Garnet), 3 normal gems of a different type are required. To obtain a rare gem (such as a Ruby), 10 normal gems are required.
