Angel Voice

As a voiceless angel-spawn, you communicate using this cantrip. Your voice fills their mind at the same volume of a normal voice, unless you use the Thaumaturgy spell to empower it to three times the volume.

While this is your only form of "vocal" communication, targets that wish to keep you out of their mind can make a DC 15 Wisdom saving throw. On success your are blocked from their mind until they allow you back in, or an hour has past and they forget to keep their guard up.

If you wish to force your way into their mind you can cast this at a higher spell, adding 5 to their saving throw for each level added, but expending the appropriate spell slot.
