Are Superpowers Legit?
Rambam Avodah Zarah 11:16
All the above matters are falsehood and lies with which the original idolaters deceived the gentile nations in order to lead them after them. It is not fitting for the Jews who are wise sages to be drawn into such emptiness, nor to consider that they have any value as [implied by Numbers 23:23]: "No black magic can be found among Jacob, or occult arts within Israel." Similarly, [Deuteronomy 18:14] states: "These nations which you are driving out listen to astrologers and diviners. This is not [what God... has granted] you."
Whoever believes in [occult arts] of this nature and, in his heart, thinks that they are true and words of wisdom, but are forbidden by the Torah, is foolish and feebleminded. He is considered like women and children who have underdeveloped intellects.
The masters of wisdom and those of perfect knowledge know with clear proof that all these crafts which the Torah forbade are not reflections of wisdom, but rather, emptiness and vanity which attracted the feebleminded and caused them to abandon all the paths of truth. For these reasons, when the Torah warned against all these empty matters, it advised [Deuteronomy 18:13]: "Be of perfect faith with God, your Lord."
"I see in the Gemara many things…which were permitted, from the realm of fortune-telling, incantations, and witchcraft…these are innumerable…as long as one's intention is for the Heavens, and he knows that the true healer is G‑d…not like those whose intention is some guiding angel."
(Responsa of the Rashba, 1:413)
