How to beat round 57
MOAB damage near the start keeps the ceramics from piling up near the exit.
- Pop the opening pair of MOABs early. A 0-3-0 Bomb Shooter or higher, a 2-x-x or 4-x-x Sniper or a strong hero ability handles them.
- The ceramics from the MOABs need explosive or buffed damage, and the rainbows need sharp or magic pierce.
- The second pair of MOABs arrives at about 12.5 seconds, so your MOAB damage must recover by then.
