@Vladosaurus @Princeharris1993 Thank you for the smart replies. We can't simply assume sasuke expended massive amounts of chakra to open that one portal. Moreover, we can't compare obito to sasuke. Obito had the mangekyo and little six paths chakra left, whereas sasuke has the rinnegan and a lot more six paths chakra. When sasuke was using amaterasu, susanoo etc with his MS, it was causing massive chakra drains, when he got EMS, he was spamming these techniques like it was nothing.

Kaguya had the rinnegan and was traveling through dimensions effortlessly (yes, traveling through dimensions is different from swapping dimensions) without any significant chakra drain and sasuke has the rinnegan as well, along with six paths chakra so it means that the chakra drain is not as massive as it would be for sasuke compared to a mangekyo user.
