Fly Me to the SKY

There are 4 camps for Steamcleaner. It means 4 Steamcleaners can pop at the same time. ( Maybe just 2 is max at West and East )

You don't need Invisible/Sneak to get this camp.

There are 2 Detectors(Place Holder) in each Camp. At the first kill Detectors (not PH one) to open route for fishing. Then fish a Detector(PH) with weak attack ( Don't kill PH Detector and don't make him DoT ) to Camp.

Any job can fish Detector(PH) but the Detector will summon a Caretaker ( Maybe Steam Cleaner :p ) before the fisher gets to camp. So make sure if the fisher is enough strong.

When the fisher, Detector(PH) and a Caretaker reach the Camp, sleep Detector(PH) and kill Caretaker. After the Caretaker dies, Detector will summon another Caretaker. Wait for next one keeping the Detector asleep. Steam Cleaner is lottely pop with the Caretaker.

Now Detector summons Caretaker just 5 times. If you can't see Steam Cleaner until Detector's 5th summoning, kill the Detector then fish another one.

Detector(PH) repops in 30 minutes. If you can't get Steam Cleaner from 2 Detectors, you should change camp not wait for repop.

Camp A ( Seiryu side ) is the best spot to camp. Camp B ( Genbu side ) is the worst spot because if the yellow gate is closed someone has to open the gate touching a Monolith at (H-13) near Brigandish Blade pop point and you have to clean 2 Detectors before fish.

Steam Cleaner is not strong, TP burn with straight tank style is enough to kill him. When Steam Cleaner pops, kill Detector as soon as possible.
