Updated on June 25, 2025, by Nahda Nabiilah:Dragons are a bit of a rarity in Elden Ring.Players will encounter many dragons in their journey, but most of them are in the form of bosses, meaning they won’t respawn, unlike other enemies. While theShadow of the Erdtree does increase the number of existing dragons, It’s still considered a small number. So, it’s essential to defeat each one of them to not miss out on any rewards. The Lichdragon Fortissax, for example, is a hidden boss that’s locked behind an NPC quest. Defeating it rewards a Remembrance as well as a decent number of Runes.
