Setup by 炽热 (Blazing)
This is one of the easiest cobless setups in roof. I was astounded at how easy this was. Only took 20 minutes
Sequence- Card 4, Doom | Imitator Doom | Cherry | Jala + Ice
The sequence can get wonky if the tempo is too fast or slow. Ideally, the doom should be used right before the zombonies are about to die on rows 2-4 right when it reloads.
Crater sequence- (4-9), 2-9, (2-7), 4-8, (4-7), 3-9, (3-7), 2-8, (2-6), 2-9, (2-7), 3-9, (3-7). For the wrap-up I did (3-8), 1-7 but the 3-8 doom isn't perfect. Parentheses means imitator. At 5:39, I accidentally placed the 4-8 doom at 4-9 which is fine but it's not optimal
There are 2 main issues with this setup
1. Sun loss is pretty crazy. I lost 2175 sun which is actually good for this setup. Multiple max difficulty rounds in a row will be really difficult to sustain.
However, on the easier rounds, it's extremely easy to gain thousands of sun which makes this setup somewhat possible to play endlessly.
2. Jack suppression isn't the greatest. All of the permanent plants will never be touched by jacks I guarantee it. However, the dooms can be blown up. This is considered a limit setup due to the fact that it's pure chance whether the dooms will be blown up or not and there's nothing you can do about it. The normal sequence has eh jack suppression but if the tempo fluctuates, the jack suppression goes from eh to complete horseshit.
Threats-
Gigas- The most threatening zombie but surprisingly easy to deal with. Gigas are at risk of crushing the imitator doom but this can be easily solved with a squash. You have no real way of cannon foddering so sometimes you might have to use a pumpkin to cannon fodder although this setup has really high damage so it's not often.
Zombonies- Zombonies are almost certainly gonna die on all rows automatically although they might require you to remove a pumpkin sometimes like at 5:35 (idk if that pumpkin was necessary to remove). However, zombonies leave ice trails which make this setup extremely annoying. You can't place plants anywhere and you have to use jalapeno to remove them.
Jacks- Can blow up dooms if you get really unlucky
Balloons- Sometimes it's really difficult to find a place to place the blover because you don't have flower pot reloaded
Bungees- Makes wave 20 extremely annoying
Gargantuars and footballs aren't real threats at all.
