Eclipse (月光 Gekkō, lit. Moonlight) is a skill exclusive to the Black Knight in Fire Emblem: Radiant Dawn. Eclipse serves as his mastery skill, and is thus non-transferable to other members of the player's army. When activated, Eclipse multiplies the Strength of its user by 5, alongside neutralizing the enemy unit's defenses (excluding ranged attacks).
An overwhelmingly powerful skill, Eclipse is capable of killing any unit, save for those with skills such as Miracle and Mantle. It has been proven, albeit with hacking, that this skill is capable of killing even the Goddess Ashera, the final boss of Radiant Dawn. Its total damage has been placed at 208 points.
|Effects||Multiplies the Strength of its user by 5, alongside neutralizing the enemy unit's defenses (excluding ranged attacks).|
|Notes||Class skill of the Black Knight class.|
- When Eclipse is activated with a sword, five hits are performed, like Astra. With a lance, it is shown to perform four hits, like Impale.
- While Eclipse isn't available as a skill in Fire Emblem Heroes, Black Knight in that game can learn Black Luna, which is an upgraded version of Luna skill unique to him. That skill most likely serves as a reference to Eclipse, as its original form would be too powerful to include.
