The Pike-Ruin Club (槍砕きの金棒 Yari kudaki no kanabō, lit. Spear Crushing Metal Club) is a Club that is introduced in Fire Emblem Fates. Like its name suggests, the Pike-Ruin Club is capable of inflicting effective damage against Lance and Naginata-wielding enemies (3x its base weapon might); however, it is ineffective against non-lance or naginata wielding enemies, dealing 4 less damage against them and suffering a -10 penalty to hit rate.
The club is based on a kanabō (金棒), a long, iron club riddled with knobs. The kanabō was a common weapon amongst the oni (鬼), a race of huge demonic ogres in Japanese folklore. Kanabō were also sometimes used by samurai to to smash their opponents armor and bones.
