Communing Roots

You extend your mind out from beneath your feet, through the roots in the earth, and send a mesage to up to 6 targets that you can feel. The target(s) (and only the target(s)) hears the message and can reply in a whisper that only you can hear. The targets have to touch the ground

Limitations: Magical silence, 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood blocks the spell.
