Combat art

First game

Echoes: Shadows of Valentia

Foudroyant Strike (Japanese: 雷迅 Thunderclap), known as Foudroyant in Shadows of Valentia, is a combat art which debuted in Fire Emblem Echoes: Shadows of Valentia. A weapon skill linked to the Lightning Sword, Foudroyant grants its user a sizable Avoid boost while also doubling the user's Attack stat, but at the cost of one square of the user's outer range.

In Three Houses, it is instead a combat art granted by Thunderbrand, and has a different effect; it increases damage, hit, and critical, and deals bonus damage to armored and dragon units.
