Alert

You sound an alert too warn your allies of danger.  All non-hostile creatures, with an Intelligence score of 4 or higher, within 300 feet of you receive a non-verbal warning of possible danger.  The recipients know that you were the one who sent the warning and know how far they are from you.  The spell does not tell them what the danger is or where it is.  Creatures who receive the warning can send you a non-verbal acknowledgement of it immediately.
