So you made it through the longest Act of Nightmare. You now have a pretty good idea of the level of difficulty that you are getting into. You have probably faced some annoying combinations on the Champion mobs (Invulnerable Minions and Shielding? I hate it!). As far as difficulty goes, you can expect the same jump from Act 1 to Act 2 in Nightmare as in Normal. This should be a relatively easy jump, all things considered. If you find yourself needing help, return to the Nightmare Act 1 guide and make sure you can clear Act 1 with very low difficulty. Act does bring in some new monsters that have are a bit trickier to take down, but the Skills and Runes section of the guide will outfit you with the best possible skillset to take those minions of hell down.
