So my first time doing the Nightmare run I was forced into taking the melee class because I didn't know that I needed to choose a class and since then I've grown accustomed to it and even started hanging back and windmilling everything away from the entryway as is the apparent norm for the melee class.

Other then putting all your money into one skill and spamming it, what are some tips you've come across? A friend of mine wants the umbrella and I want to get it for her lol
