@BurningGodzilla07 True and not true at the same time, the spells recorded in the book are defensive, but Dr. Strange has many time used the book for way more than that. Such as resurrecting his brother and turning him into a vampire, invoking the Vishanti to release magical blasts to erase magical beings, mind controlling others, shutting down someone's mind, other spells that invoke other beings (which include Balthakk, Cyttorak, Hoggoth, Ikonn, etc that have very offensive spells). So that saying is completely contradictory in the comics, and the creator of the post didn't specify whether or not its MCU or Comic and if it was MCU, then that statement doesn't apply,
