Similar to its predecessor, Sengoku Musou 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 8 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. Note that rare skills are inaccessible unless a rare skill gem is used to unlock them.
