Well, that is a moment when Cheat Engine is awesome :3 You can just give yourself Gurthang's. But if your doing that, you would be better off with a MGL.
That won't be necessary, because I just got one
That +360% attack bonus fits Nitori quite well.
Also, some of the 30F randoms seems to be becoming doable. I have beaten up Suwako, Orin, Rumia, and Tenshi so far, and gotten Utsuho down to the point when she destroyed my entire party with a single Giga Flare. No drops yet, though.
EDIT: Make that 18F v3 as well. The battle must have glitched out quite badly, though; for whatever reason, he just refused to use any spell other than Form Destruction after his first Form Shift , even when I didn't even have the time to do any damage to him in between... And then his final form went down with a single 800k Blazing Wheel. No idea what happened :V
