Teleportstone

Can be purchased from Horadric. Teleport stones allow for fast traveling. So far the only locations you can travel to are
 * Sweet Home
 * Dead Horse
 * Lighthouse
 * Quarry
 * Mountain Fort
 * Talking Skull (Stranger Sins DLC)
 * Refugee Camp (Game of Crone DLC)

There is a cooldown but the stone can be used more than once. Available from version 1.023.

Cooldown
After teleporting to a location, the teleportstone goes on a fixed cooldown of 30 seconds (decreased by 2:30 minutes, bug?).

Note: The cooldown only goes down while the inventory or any other UI is closed. For example it goes on halt if the player is looking inside a chest, has the map open, etc.

Note: Having more than one teleportstone does not allow you to teleport multiple times in a row, as the cooldown affects all of them at once.

Usage
The teleportstone can be used by simply right-clicking inside the inventory. If you are carrying an object such as a log or a zombie it will teleport with you. Currently there are 7 available locations to teleport to.

Note: You cannot use the teleportstone while in the Dungeon.

Trivia

 * The Teleportstone is a reference to the Hearthstone, from World of Warcraft, with similar shape, name and colour.
