A new Elden Ring mod that has been shared online this week makes the game considerably more challenging with some choice tweaks.

The Prepare to Die mod not only increases enemy stats but also introduces a revamped AI that allows enemies to see and hear the play from much further and generally makes them smarter. Fast travel mechanics have also been changed to make everything more challenging.
