Gunslinger Build (Lv. 10-200)

Even though I do have Bishop friends that are willing to train with me, some for pots, some just because they get good exp as well, I'm still leaning towards Cannon -> Air Strike. It definitely looks like a good build for anyone for who bossing isn't the highest priority.

With one point in it, I'm hitting something like 8k to 15k at level 122. Maxed Air Strike at early level 14x should be able to hit something like 26k-46k, I'm guessing. That's enough to kill most monsters in 2-3 hits. The main advantage of Air Strike over other skills is that it lets you hit things without being near them at all. No matter how fast you can kill with your other skills, you'll hit a point where you can't kill any faster because they're too far away. Even if it doesn't do quite as much damage as Torpedo, or help with bossing, Air Strike will improve your killing speed overall.

I also think it's possible for a 14x Corsair to kill Harps or Windraiders nearly as efficiently as 12x mages with a good level of Air Strike and Torpedo. The implications of this are obvious, I think.

I think Air Strike ignores bullet attack or something. It is a little weaker than you'd expect it to be from the %, but not that much.
