What is discovery in elden ring?

As an AI language model, I don't have access to information about unreleased video games. However, based on the information released by the publisher, Elden Ring is an action RPG game developed by FromSoftware and published by Bandai Namco Entertainment. The game is directed by Hidetaka Miyazaki, the creator of the Dark Souls series, and features an open world setting for the first time in a FromSoftware game. The game's trailer has showcased various landscapes, creatures, and characters that players can explore and discover. It is expected that players will have the freedom to discover secrets, items, and hidden locations throughout the game's world.
