5 - Sowrd of Night and Flame

Highlighting the faith portion, the unique Ash of buy Elden Ring Runes War Night-and-Flame Stance has the comet beam and the fire the first scales with intelligence and the latter with faith. The beam is way better at doing more damage and being easier to use in battle, that being said the fire damage is good for bosses weak to fire and also great against mobs. That being said it definitely has a long windup time so be aware of that, but when you use it for mobs or bosses that are weak to fire, you can get massive damage from the faith portion on the sword of Night Flame.
