Endless 2 NG+ 100+ waves made easy [Defender's Quest: Valley of the Forgotten DX]

I show my character builds quickly at the beginning. Pause if you want to see more details, but I've mostly built them based on the Steam post linked below (which is for NG+ Extreme of the final boss), so using this video as reference is unnecessary. I show my placement at around 1:57, including all of my defenders' attack priorities. As money comes in, I place the rest of my defenders and max everyone out. With this formation, reaching wave 100 is easy as long as you replace anybody who gets defeated and pay enough attention to make sure nobody makes it through. If they do, use spells to take them down. Once I had everyone on the field, it was mostly just auto-pilot and using Berserk just to make things a little faster.
