Haha no problem man! ALL numeral things but the Hours i think so far can be changed while in that state (Saving) and can be changed without any problems. AP/MP/HP/SPP/Etc all with CE can be modified and kept. Atm the trainer doesn't do much so i rec using CE for the time being til they update.
the trainer allows unlimited health, mana, and special attack, as well as upgrade points, and Gil.
"not much"?
modifying all those traits is not even necessary.. since the trainer keeps you topped off constantly
