I had an idea to solve the problem of people always complaining about there not being enough content for high level players. You could add a battle tower like thing with infinite randomly generated floors, getting more difficult as they go. Clearing a floor could give you progressively more xp as you go and maybe at certain milestones you could get a unique item. I am not a coder but from my understanding this would not be incredible difficult to code. However I can’t think of a way to make this lore friendly sadly.
