The final campaign – “Even Angels Cry” [7th campaign – 1st mission].

concurent, up to level 4, it only requires a million experience points. At the end of the second final, I spent a lot of turns skipping, which allowed me to upgrade the Staff of Eight Aspects of Ashi to level 5, which required about 8 million experience points. And I wouldn't say that it's very easy on easy difficulty. I couldn't complete 4 missions from all campaigns on normal difficulty, but on easy difficulty, it's more or less manageable.
