Sending stone

Sending Stones come in pairs that allow the user to cast the Sending spell to the holder of the corresponding stone.

Description
The stones are smooth and sometimes carved so as to be recognizable as one of a pair. The stone found in the Sutan residence was described as being a single polished palm-sized river stone. Yussa Errenis's stone was also a smooth polished river stone but light blue in color.

Campaign Two: The Mighty Nein
Lord Diedric Sutan had a sending stone which was stolen by Caleb Widogast during the party's break-in of the Sutan residence. The holder of the corresponding stone was Ionos Jagentoth.

Yussa Errenis and Allura Vysoren held corresponding stones. Yussa had instructed Wensforth to use it to contact help in the event of an emergency, and he did so when Yussa disappeared into the Happy Fun Ball.

Essek Thelyss gave a sending stone to Dagen Underthorn so that he could contact the party in the event that the Tombtakers arrived while the party explored the ruins of Aeor.
