* To set the place that you wish to teleport to, activate the stone and right click a vein tile, then choose 'Set teleport marker'. Thereafter you can teleport to that location by activating the stone, right clicking on the ground and choosing 'Teleport'. You will be taken there instantly and the stone will disappear from your inventory.
* Your mount and/or pet does not teleport with you.
* Used on a vein tile only while underground.
'''Warning : This seems not to work on created (transmuted) veins. You can set the location, but it will not teleport you. This is being tested to verify the situation.'''
