While the questline is mainly about following the story and interacting with the right NPCs, there's another requirement that may catch some players off Elden Ring Runes guard. To progress through Brother Corhyn's quest, you will need a certain level of Intelligence. This is because some of the key conversations and actions required to complete the questline are tied to Intelligence-based interactions.

If you're playing with a non-Intelligence build, don't worry—you can always respec your character. Respeccing in Elden Ring requires the use of Larval Tears, a valuable item that allows you to redistribute your attribute points. By respecing and adding points into Intelligence, you can unlock the necessary abilities to progress with the questline.

For those using a full Intelligence-based build, this requirement will be no issue. However, if you're unsure, stock up on Larval Tears just in case you need to tweak your build. These items can be found throughout the game, but it's always helpful to buy Elden Ring Runes have a few on hand for any future respec needs.
