that shouldn't be too much of an issue. If you only went back to grind, it's fairly easy without using the MC's chimera abilities. Then, when you're done, just teleport back to Dragon Peak, and surrender to a group of Kobold enemies to gain it back. I recommend the grinding beforehand, because after a certain amount of surrenders to kobolds, they do eventually take you directly to the boss fight. I suggest getting to level 30 before returning to Dragon Peak, or restarting the game entirely.
(I'd say you should probably restart if you haven't leveled up each of the MC's forms separately, bc they all gain XP and skills independently from one another)
