Rapport Spores

You have absorbed the knowledge of a unique species of fungus that enables telepathy. Once per short or long rest, as an action, you can use these spores to psychically link up to eight willing creatures of your choice within range each creature to all the others for the duration. Creatures with Intelligence scores of 2 or less aren't affected by this spell.

For the next [proficiency bonus] hours, the targets can communicate telepathically through the bond whether or not they have a common language. The communication is possible over any distance, though it can't extend to other planes of existence.
