Weapon Kill bonus

Weapon Kill bonus in Fire Emblem most often refers to getting double weapon experience when a weapon kills an enemy. Weapon experience is needed to go up in weapon rank. However, in Path of Radiance, there is no Weapon Kill bonus, so that is why it is quite difficult to raise weapon rank in that game. Seisen no Keifu has another Weapon Kill bonus. When a weapon has killed 50 enemies, it gains the Critical ability. For every kill the weapon makes after that, its chances of landing a critical hit improve.
