DFOArchive: Ruthless Cell Gaper

Struggle

A gauge appears next to your character. If you step outside of the green area, you take damage and the gauge fills up.
Fill up the gauge will put you on hold state. Another player can bump to free you. Note that you can manage this gauge through jumping.

Abyssal Turbidity

Gaper traps everyone in each corner then release one player. This player will have a green circle underneath them that shrink over time.
When the free player touches a trapped player, slashes appear and free said member. At the end, if all 4 players are freed, touch Gaper to get groggy.
The pattern seems easy but the trick here is that this pattern takes about 30 seconds, so you need to make sure you don't rescue other people too fast. Since the shrinking green circles are your safe zones, rescuing too fast meaning you don't have enough circle to survive.
Another thing to note is that you will see panel closing in vertically and horizontally. You need to check where the panels are coming from and rescue the person closest to them first.

Reverse Struggle

Gaper spawns various circles on the map. They start out as grey, then turn green. Stay inside the circle before it turns from grey to green.
Once it's green, touching the circle will reduce your HP greatly, so it's best to dodge Gaper other pattern while inside the circle.
You want to stay inside the circle because right after, everything outside circle take damage. After cast bar, inside circle take damage, so run outside.

Gaper Clones

If you see clones on the map, attack them. Often time you can have green circles around everyone. Make sure you clear pattern while keeping distance from each other.
Then a gray circle forms around one person. This is the safe zone that everyone should stay in.

Obliterate

Gaper creates 2 whirlpools. 2 Players should enter each pool.
Once inside, you see a bunch of grey circles. You will see Gaper and his clones. Make sure to note the clones' location.
As those circle turn green, they cause damage at touch. When circles turn grey again, run to the clone and eliminate them. Once clones are done, eliminate Gasper.
Afterward you can move out. If both team success, pattern is complete.
