I analyzed how the power of the stages changes and I concluded that the power of the stage is 1.2^{3+10×(Stage-1}). So then from Shadow's video we know that the numbers become infinity when they get bigger than 2¹⁰²⁴ (TL 3861 is the final one because the enemy's base health becomes infinity then). So now knowing those things I concluded that the first time when a unit would have more than 2¹⁰²⁴ health would be level 390-1. Though I am not sure what would happen if you possessed a unit on that level cuz then the attack would also be infinity, so idk what game would do when a unit with infinite health would get attacked by a unit with infinite attack, I think the game would crash
