Details
attacks similarly to with a detection range of 5×3. When the zombies enter the range, fires 8 heavy fumes 4 times every 1.9 seconds. Heavy fumes explode on expiration, damaging zombies in 5×5 area.

explodes on death, dealing 1,800 cremator damage and freezing all the zombies on the screen.
Pros
- High area efficiency — Each attack cycle can hit several zombies, generating far more total damage than its base cost implies.
- Wave specialist — Peak performance during the high-density flag-wave moments when zombie clusters are largest.
- Burst damage — * (100 + 100 × 8) × 4 (Fumes) burst clears weaker zombie types immediately on contact.
Cons
- Single-zombie waste — Area damage is overkill when targeting lone zombies in empty lanes.
- Moderate durability — 300 requires a wall plant in front to survive long enough for multiple attack cycles.
- Timing critical — Peak value requires timing placement around incoming dense waves, not pre-placed broadly.
1
Hold off placing Oblivion-shroom until you see a large flag wave incoming — peak enemy density maximizes each explosion's hit count.
2
Pair with a slow plant like a snow variety to push clustered zombies tightly together before Oblivion-shroom fires.
3
In large maps, a single Oblivion-shroom placed centrally can cover zombies approaching from multiple adjacent lanes simultaneously.
4
Protect it with two columns of plants in front so it fires at least four cycles before being threatened directly.
