Convocation Stone

Wondrous item, rare (requires attunement)

This dark gray, rough-hewn granite disk is 1 foot in diameter and 2 inches thick with chiseled symmetric runes on both sides. To activate the disk, two creatures with at least 3 Intelligence must hold the disk and concentrate for 3 rounds on a specific individual they both know, with concentration checks required to maintain concentration if they take damage or are otherwise distracted. If either creature’s concentration is disrupted, the 3 rounds of concentration must begin again. If the concentration is completed and the creature they have chosen is on the same plane and within 900 miles of the disk, that creature receives a mental message with the names of the two creatures and a request that it be teleported to them. The target creature may ignore the request or may accept it as an action but must accept it within 1 round or the magic is wasted. If accepted, the target creature is transported to the location of the convocation stone (as teleport). If the target creature fails to arrive, the creatures that triggered the convocation stone receive no information about whether the creature refused their request, was out of range, or was otherwise unable to accept the teleport. A convocation stone can be used four times per day, and each attempt to contact a creature, whether successful or not, expends at least one daily use.

A single daily use allows one Medium-sized or smaller creature (carrying gear or objects up to its maximum load) to teleport adjacent to the stone with no chance of error. If the area around the stone is unable to support the creature, the teleportation fails. Teleporting a Large creature costs 2 uses and a Huge creature costs 4 uses. Casting teleport on the stone restores one daily use, while casting greater teleport on the stone restores all four daily uses.
