You're not merely the amalgamation of every Hokage, no, you’re also the latest and most powerful Incarnation of the Uchiha progenitor Indra Ōtsutsuki himself. You’ve gained all the combined physical ability, chakra, skill, wisdom, talent, jutsu, and knowledge of every single incarnation of Indra that has existed. Indra was known for excelling at everything he tried, a genius of caliber almost unseen. You now possess this talent and can with almost contemptuous ease learn and develop anything you wish. As the creator of Ninjutsu himself, you’ve gained enormous talent and genius with jutsu in particular. Creating a new jutsu is now as simple for you as it is for a normal man to construct a sentence. Your chakra quality and potency is doubled and your chakra control is perfect. All your Dōjutsu are further amplified by an order of magnitude.
