Nice. Soon you won't even need to take out the copters yourself ;P
Worked for me and only had boots from wave 15 Mass. Endless spires and nightmare chest. I did have to make sure to take out the chopper from the south, and I used a Mass. Camp. Fusion Draketooth.
Pretty easy run. Sit on DST/aura stack with Speedy Gemstone. Keep an eye on walls/auras.
