Luce (ルーチェ Rūche) is a high-levelled Light Magic tome from Fire Emblem: Rekka no Ken. A more powerful version of the A-ranked Light Magic tome Aura, the Luce tome may be obtained in the final chapter of Rekka no Ken by defeating the Kenneth morph. When cast, swirls of divine energy will centripetally congregate into the centre of the immediate battlefield, charging up and eventually giving rise to an orb of light. As this orb of light absorbs more and more energy, it will eventually shatter and send a fury of light stakes in the direction of the selected enemy target.
The Luce tome is widely considered to be the best Light Magic tome in Rekka no Ken, surpassing even the likes of the holy Aureola tome, owing to the fact that it possesses a higher Might and Critical rate than the latter tome does. However, it lacks the ability to deal effective damage to Nergal and the Fire Dragon, does not possess a boost of 5 Resistance, and is more cumbersome, so Aureola is usually better during the final stages of the final battle.
"Luce" means "light" in Italian, and is derived from the Latin word lux.
