This build was made and tested with 6k main stat heroes in mind. It is made to be as safe and consistent as possible. For me, a slow builder, I average 1-minute build time, and 1m 40s for wave 23 and 24.
Build Notes: The reflect beams are to protect your TB monk from the occasional spider web that's cost my a run or two.
Wave Note: When I run this map, I just use a single TB monk for wave 23 and 24 and I upgrade throughout the wave. During wave 24 I bring in the last 3 heroes to get 4 genies at the end of wave 24.
