I'm still fairly early on in Disgaea. I've just started Map 4, and Laharl is only level 18 or so.
I see that I have the option to Transmigrate him. As I understand it, transmigration makes a lot of sense for my newly-created characters, as I effectively upgrade what class they are (like Cleric to Priest or Bishop). However, for characters like Laharl and Etna, they can't upgrade their class or change class, so the only benefit seems to be that they may get some more ability points, depending on how much mana I spend.
I'm left with some questions about when it's worth it do this. Are the ability bonuses cumulative, such that if I transmigrate him 10 times, I'll get 10 times worth of stat bonsues? Or will my 2nd transmigration wipe out the ability bonuses of the first?
If they do stack, does it ever make sense to transmigrate as a Genius, since it costs a heck of a lot more mana (8000) to get 10 points, whereas I could transmigrate 10 times for +1 ability points (only costs 10 mana each time!)?
If it doesn't stack, will I ever need to transmigrate again once I've transmigrated at the Genius level?
What's the "Inheritance Bonus" percentage, and how does this affect things?
