In Tasha’s Cauldron Of Everything, Soulknife Rogue gets the following feature at 3rd level:
Psychic Whispers. You can establish telepathic communication between yourself and others—perfect for quiet infiltration. As an action, choose one or more creatures you can see, up to a number of creatures equal to your proficiency bonus, and then roll one Psionic Energy die. For a number of hours equal to the number rolled, the chosen creatures can speak telepathically with you, and you can speak telepathically with them. To send or receive a message (no action required), you and the other creature must be within 1 mile of each other. A creature can’t use this telepathy if it can’t speak any languages, and a creature can end the telepathic connection at any time (no action required). You and the creature don’t need to speak a common language to understand each other.
Can this be applied to enemies? If yes, can enemies stop this telepathic connection?
