This feature would allow us to downgrade a Ninja back to Level 1.
Why You ask?
Let me tell you, alot of new players have no idea how the game works. Takes time for them and alot of mistakes to understand the game, Some waste their resources in nijas that won't even have a purpose or use after level 30 or 40. Some invested alot in one ninja that was part of their main squad untill they charge their lucky 10$ and get an awesome Ninja and replace their old core. So, those ninjas who get replaced sit there forever in our backpack never being used. So I tought...
What if we had a feature in the game that allowed us to make that hero level 1 again. And in exchange we get 50% of the resources we used on them. Why 50%, because 100% would just be imbalanced.
Food, Aweken Materials, Cultivation Runes. (No Fragments), will be returned after use.
Such Feature Would make the game So much more User friendly and newbie friendly and plsu it will allow old players to give that small boost for their OP ninjas that need just 1 or two levels of cultivation.
I would even understand if such feature came with an item lets say "Backtrack Rune" or "Reset Scroll" that we could buy with Ingots/Coupons. I don't mind. But I feel that Such feature would be Necessary and amazing to have in the game.
It could even have 2 variants. the 50% and a 100% one.

Please consider.
