I delved again into the item world in Disgaea 3 to pick up a few more professionals, but it gets tedious rather quickly, since you only find them in small amounts. I’ve only collected 60 levels total of them so far, and ideally you want 100 for a 100% critical rate.
So, to break up the tedium, I’ve also started working on raising up some other characters, since if there’s one thing better than having an ultra-powerful character, it’s having an army of ultra-powerful characters… The Big Bang skill is the best for powerlevelling due to the layout of the farming levels, so I’m working on fist users first, including Adell (one of the Disgaea 2 DLC characters), my druid, and my female ninja. I’ll have to use the Class World to transfer it to some of them though, since they can’t learn it on their own. I also put Adell through the standard five reincarnations for story characters, just to get it out of the way.
(Edit: Actually, reincarnating them into martial artists would probably be cheaper and quicker, for the non-story characters, especially since I have to do it anyway since they haven’t reached their maximum tiers yet. I could do it again for cleric skills too, like I did for my own character. The reincarnation costs go up, but mana is pretty easy to generate right now. I’ll still have to use Class World for Adell and Mao though.)
(Edit edit: And I still had some time to kill, so I went back and finished unlocking the rest of the DLC characters. The fights were no problem, though they reused the basic classroom map a bit too much. Looks like they all have unique skills and evilities that might come in useful, though. Kogure’s fight was a bit different in that it went into a completely different style for a little while, too.)
