Infernal Tyrant Climax (Brutal) Cheese tutorial in description

the Bad Guys combo (or kimono champs) is pretty important
BATTLE ITEMS: speed up & sniper the cat

once the battle starts, wait for the doge dark to come and kill it with pizza/courier + dual eraser spam

when the gory appears, start spamming everything except healer, combo units or warlock. Start counting the amount of Sir Rels that appear. 4 appear in total.

Once the gory dies, stop summoning courier, pizza, dual eraser. This usually happens while the second sir rel is alive or after its dead, or when the third sir rel is summoned.

(you probably need to do your own trial and error for most of these)
Soon, the Haniwanwan will soon follow the same fate of the gory.
immediately stop spawning everything (this is usually when third sir rel is alive or after its dead)

Now, is when luck and skill comes into play.
ensure that the 4th sir rel can kill off your couriers and pizzas (ur lucky if a pizza hits a sir rel once or twice but not more)

once all of them are dead, ensure sniper is on, summon boulders and hope it dies before your base does. Once the 4th sir rel is dead and there are no units on the battlefield, congratulations, you've completed the hardest part of the cheese.

Once a li'l doge spawns, wait until it hits your base and summon healer. (now is just luck whether the doge's dodge procs a small amount of times) and then start summoning Warlocks.
(summon about 3-4 healers with their attacks not synced so that the doge doesn't bite your base too much)

when there are 2 lil doges, summon boulder (usually twice if they don't dodge) to kill one off. This prevents your base from losing too much health.

My warlock is level 40, thus I only need to stack 4 of them. Level 49 warlocks will only require 3 warlocks to be stacked, tho 48 is possible if you summon a boulder to do 80+ damage to the base before the warlocks hit it (but make sure the boss doesn't summon from it, if the enemy base was untouched then u can use a boulder)

if Lv30 warlock, u need to stack 5. so try to get it to level 36
lv35 would need 4 to be stacked but yet again, your healers or boulder need to deal at least 80 damage but less than 20k to the base. but works

once the warlock stack hits the base and you know its going to get one shot (there won't be 1hp of base remaining as shown in vid, so lucky the first brutal stage is cheese able) then congrats, you got jetpack cat just like how I did.
