Quote (Mr Textbook)
Nightmare - There won't be as many rules now, as things will start to become very hard.
Act 1
You may not use any level 18 skills during your time in Act 1 Nightmare. Once you reach Act 2, this rule no longer applies.
You must find a unique bow anywhere in the Catacombs prior to going to Act 2 (Exception: You may visit act 2 only to quest bug Andy)l. Screenshot this with your stats screen open.
While fighting Andariel, you may not use antidote potions. Screenshot your fight with Andariel.
Found this while doing the den. Kicks are doing decent damage so far. Only having 2 kicks per attack is painful though.

Managed to kill my merc. Play nice!!!

I thought I told you before, only room for one Queen bee here
