How to beat round 66
Steady MOAB damage matters more than burst here, because the waves are spaced out.
- Make sure your MOAB damage can finish each wave before the next one arrives about seven seconds later.
- The 3 fortified MOABs at the end have 400 health each. Save an ability or a hero ability for them.
- Your ceramic splash from round 63 handles the ceramics, and sharp pierce finishes the rainbow children.
This round is a good benchmark for the MOAB-heavy rounds in the 70s.
