Q:

Diablo II LOD How to change difficulty levels online?

I'm currently stuck in hell mode with an lvl 56 character, how do I get back to nightmare?

A:

As soon as you're in Hell difficulty, you'll only see Games that are on that difficulty. You can create a Nightmare game by yourself any time however... or ask a friend who is in Nightmare difficulty if he could tell you the name of an open NM game.
