Similar to its predecessor, Samurai Warriors 4 enables players to affix their weapons with a variety of skills. These are divided into four different categories based on their effects and usage. A single weapon can only carry a maximum of eight skills at a time. By collecting skill gems from defeated officers or disassembled weapons, players can use them to strengthen their arsenal or purchase more skills at the shop.
Rare skills are inaccessible unless a rare skill gem is used to unlock them.
- * means it is a rare skill.
