The Yewfelle (イチイバル, Ichii-bal in the Fire Emblem Museum, alternately translated Ichaival in Fire Emblem Treasure) is one of the holy weapons in Fire Emblem: Genealogy of the Holy War and was the weapon of Ulir. It grants the Life skill to its wielder as well as +10 Strength and +10 Speed, but only units with major Ulir holy blood may use it.
In the game, the only people who can use it are: Briggid in Chapter 3 till the end of the first generation, and her son Faval when he is recruited until the end of the game.
