Arme's 4th job skill "Deep Impact," huh?
You're getting hit by multiple huge meteors that cover up the whole screen. Of course it's gonna be OP. Still, not sure if it does more damage than Black Space or not, because it's really hard to fit a skill like that somewhere. The meteors go everywhere and not all of them hit a single target. Maybe at least two or three meteors will.
Time to redo the list:
1.) Lass' 1st job ST skill "Raven Walker"
2.) Arme's 1st job cash skill "Firestorm"
3.) Lire's 1st job ST skill "Stardust Rain"
4.) Ryan's 2nd~4th job skill "Nephilim"
5.) Dio's 1st job Left Tree skill "Necrotic"
6.) Dio's 1st job Right Tree skill "Onrush" (with AP reduction bonus from 2nd job)
7.) Arme's 4th job skill "Deep Impact"
8.) Sieghart's 1st job ST cash skill "Mocking Blade"
9.) Dio's 1st job Left Tree skill "Black Space"
10.) Arme's 2nd job skill "Big Bomb"
11.) Jin's 2nd job skill "The Glow" (Burning)
12.) Mari's 1st job skill "Eraser"
EDIT: Yep. Sure does do more than Black Space.
