How to beat round 131
Only top-end single-target damage will do.
- Blimp-focused Paragons carry this round. Several Elite Snipers, Sun Temple or True Sun God and The Anti-Bloon add support, all boosted by Jungle Drums, MIB and Overclock or Ultraboost.
- Since the ZOMGs arrive about two seconds apart, spread your abilities instead of firing them all at once.
- Stall with Maim MOAB, Cripple MOAB or Super Glue, and keep area blimp damage for the 72 Fortified BFBs that come out.
