Staff of Ocean's Echo
Listening closely to the conch shell atop this staff. one could swear they could hear the ocean’s waves. Beyond the waves of the ocean, the last message spoken into a conch shell echoes. While you touch one such staff, you can use an action to cast the sending spell from it. The target for this sending spell is any other Staff of Ocean’s Echo. Once any message is spoken into the Conch Shell it overwrites any prior messages. If no creature currently bears another staff, you know that fact as soon as you use the staff, but still overwrite any previous message. As a free action the bearer of a Staff of Ocean’s Echo can place their ear against the Conch Shell to listen to a repeat of the last message spoken into a Staff of Ocean’s Echo.
Once sending is cast through the staff, it can’t be used again in this fashion until the next dawn.
Casting Time: 1 Action
Duration: 1 round
You send a short message of 25 words or less to a creature with you are familiar (in this case all other staffs). The creature hears the Message in its mind, recognizes you as the sender if it knows you. and can answer in a like manner immediately. The spell enables creatures with Intelligence scores of at least 1 to understand the meaning of your Message.
You can send the Message across any distance and even to other planes of existence, but if the target is on a different plane than you, there is a 5% chance that the Message doesn’t arrive.
