Wondrous Item, Very Rare
This dodecahedron is covered in a grainy sapphir coloured material, with dwarven runes written along all its edges.
A creature can spend one minute concentrating and touching the dodecahedron to teleport itself and up to 6 other creatures that are also touching the dodecahedron to a known location on the same plane of existence. A successful DC 15 Wisdom check is required to determine how close the creatures are teleported.
A creature can chose instead to teleport itself and the other creatures to an unknown location, decided by the Dungeon Master.
The dodecahedron has one usage that it can attempt to recover once a day at dawn on a successful DC15 check.
