I was just doing the Eden TI quest. With battle manual, the ground petits were giving me 3510 exp, so when I turned it in I expected
400 * 3510 = 1,404,000 exp. The battle manual effect was still on when I turned it in. Instead, I got half of that, 702,000 exp. It leveled me up from base 89 to 90 and reached up to about 33% of level 90.
According to the iro wiki, pre-rebirth level 89 to 90 is 900,000 exp, so the upper limit should have been about 1,800,000 exp, right? Is there something I missed?
