yes it does, every main character have his nature cultivation, so if you change like lightning for example you have to finish them again, but if you rechange to fire your progress won't be deleted, so you can change to any main, your fire main progress won't be deleted

That was exactly what I was afraid of XD

Thx for your help

Hello!

I would like to correct this information. Changing Main Characters will not affect your current progress in Nature Training. It will be saved and you can continue finishing it after you go back to your chosen Main Character. The Fire Gamer seems to misunderstood your question or he worded his answer wrongfully in the way you got it wrong. Hope you understand and thank you.

that's what i've said, but in a delicate way XD, thanks for make it easier, and i just meant that this progress won't stay the same for the other mains except fire , for lightning,water,wind,earth he needs to refinish the missions to activate the nature cultivation.

hope you did understand XD.
