With the update released on August 28, 2018, an improved teleportstone version was released. You can buy it from Horadric for two silver coins. You can buy a teleport from the very beginning of the game and you are limited only by the wealth of your wallet.
To use the teleportstone you must enter your inventory and use the item. Then 3 options will pop up: use, equip, destroy. You must select the use option.
After choosing this option you will be able to choose the zone to which you want to teleport: sweet home, dead hours, lighthouse, quarry. However, Teleport has a loading time of about 4 to 5 minutes. So after each use you have to wait a while to change your location.
