Round 91
Round 91 in BTD6: 100 Fortified Super Ceramics and 20 BFBs. RBE, cash and how to handle this heavy ceramic round.
Guide
Round 91 combines a 30-second stream of 100 Fortified Ceramics with 20 BFBs that arrive between about 7 and 17 seconds in. Past round 80 every Ceramic is a Super Ceramic, so each of those 100 has 120 health on its ceramic layer.
The BFBs (about 854 health each after ramping) then release 80 MOABs and 320 more Super Ceramics on top of the stream. That mix of tough ground bloons and a big BFB wave is why round 91 often catches out defences that were built only for blimps. RBE is 71,160 and the round pays $4,000 from pops plus a $191 bonus.
Bloons in round 91
- 100 × Ceramic Bloon (Super, Fortified) (0–30 s)
- 20 × BFB (7.4–17.4 s)
How to beat round 91
You need serious ceramic damage, not just MOAB damage.
- Fortified Super Ceramics: use high damage per hit. Sun Avatar and Sun Temple, Glaive Lord, Inferno Ring, Plasma Monkey Fan Club, Grandmaster Ninja, Wizard Lord Phoenix and the Bloon Solver are reliable.
- BFBs: 20 BFBs in ten seconds is a decent single-target load. Elite Snipers, MOAB Eliminator, Sticky Bomb and Plasma Accelerators handle them, with MOAB SHREDR or Rocket Storm for the MOAB children.
- Buffs: Berserker Brew alchemists, a Jungle Drums village and Overclock or Ultraboost engineers raise ceramic damage a lot.
- Abilities: fire area abilities as the BFB children and the ceramic stream overlap, roughly 15 to 25 seconds in.
In CHIMPS a Spike Factory with Spiked Mines or Super Mines near the exit is a cheap insurance policy for the ceramic leaks this round can cause.
