Gae Buidhe

Gae Buidhe: Yellow Rose of Mortality (必滅の黄薔薇(ゲイ・ボウ), also translated as The Golden Rose of Mortality) is a cursed spear 1.4 meters long that inflicts wounds that cannot be healed naturally or with medical ninjutsu. Bishamonten keeps it wrapped in a talisman cloth to seal its abilities until he requires them.

Unlike most other notable weapons in the continent, the abilities of this spear are passive in nature. It instantly actualizes its curse of mortality upon striking the enemy, of which lowers the opponent's vitality, thus limiting healing and regeneration abilities to the point where the opponent received the injury. The effect cannot be dispelled, and canceling the curse requires the destruction of the spear or the death of its wielder.
