Endfield Sky King Flats Auto-Defense Level 4

Arknights Endfield Sky King Flats Auto-Defense Level 4 The main idea is that in each of the four direction, you need 1 marsh gas backed by mortars as your damage dealer. 0:23 In the north (main gate), you only need 1 marsh + 1 mortar, supplemented by either deluge or acid soaker. 0:18 In the southeast (toward the water mill), you need 1 marsh + 2 mortars. This will deal with both the ground floor and 2nd floor. The southwest approach has the toughest bosses and needs at least 4 mortars plus 1 marsh and 1 acid soaker. In my case, I placed 2 mortars at the ground level (0:10) and 3 more at the top (0:32) which will co-fire at other routes, plus a backup Armor Fragger where the brutes jump up. There is also a backup marsh gas up here as well for leftovers from the other route.
