Beginner's guide request
Dear all,
I just got into playing this game (Disgaea 7) and I find it very hard to progress. I see that online there really isn't any beginner friendly guide. I have made it through Ep2-4, but unable to take even one attack from the jumbified boss. I wonder how does one progress in early game? Should I just grind those that I can beat and hope to level up as much as possible?
Also I am really not sure what class I should use, it would be great if you could provide some starting class combos.
Thank you!
