Quick side note about reincarnation: don't know about D4 but in D3 when you reincarnated a non generic character (Mao, Almaz, etc) they would gain a permanent 5% aptitude bonus in all stats for the first five reincarnations or so.
It was the first 5 (+25%), though I don't remember if it was from reincarnation in general or if it was from a Genius-level reincarnation. This bonus was separate from the normal +100% Aptitude cap via Class World. I'm not sure on the Disgaea 4 mechanic yet (T.T no copy yet) but I imagine it's similar still, though a higher cap (300%).
Also, about the Magichange Weapons (for Disgaea 3, anyway), I forgot there's some shenanigans to be done with Puppy Paw Stick killing MCW-wielding enemies to get a weapon with obscene stats in the Land of Carnage. Kind of a post-game only thing, sure, but there's that. They were better than Level 200 R40 Weapons but had the whole issue with reverting when a stage was finished with it unequipped :/
Dunno if the same will be the case in Disgaea 4 with the Level 300 equipment. They did add more to Magichange with the Giant Monsters, though, to increase AoE sizes and such.
