The bonus dungeon is pretty damn difficult.

Unfortunately, Long Range, Read Ahead, Gained EXP Up, Gained ABP up, and Lure don't stack over to Freelancer/Mimic. In my opinion, the only job worth the scratch out of the three is the Gladiator. !Finisher will randomly hit for 9999, or at least a critical hit of ~4000. And Bladeblitz is just obnoxious.

And the first optional boss after Shinryu and Omega freakin' sucks. >_>
