Because of the large assortment of weapons in Elden Ring, every mage can find a seal to their liking, but players with Black Flame spell builds will not be able to ignore the Godslayer's Seal. As the sacred seal of the Godskin Apostles, this weapon will buff all Godslayer Incantations by 10%, providing an essential late-game bonus. This weapon also has one of the highest Faith requirements, which can be a stumbling block for some mages.
