Luna (Skill)

Luna (月光, gekkou, lit. Moonlight), also known as Moonlight Sword (月光剣, gekkouken), is a skill first introduced in Fire Emblem: Seisen no Keifu. When activated (skill% on attack), it allows the user to bypass enemy defense, totally or partially.

Seisen no Keifu
In Seisen no Keifu, this skill is known as Moonlight Sword and, when activated, completely ignores enemy defense. However, there are two restrictions about it: first, it will not trigger at the same time as Shooting Star Sword; second, it may only be inherited by infantry sword users - like Sword Fighters, Dancers and Thieves.

Only Holyn and his children (if any) may have this skill.

Thracia 776
In Fire Emblem: Thracia 776, it works as in the previous game, but it can be taught (through a Skill manual) and effectively employed by any unit. Furthermore, it may also activate at the same time as Sun Sword and Shooting Star Sword, should a character have two or more of such skills.

Mareeta and Galzus start with this skill.

Sacred Stones
Pierce, the class skill of the Wyvern Knight class, is basically Luna renamed.
