WOW Gold: Portals can also be used outside of instances at the Meeting Stone
Teleportation, Portals, and Summoning: All three of these are methods that Mages and Warlocks use to travel around the world. The first one, teleportation, WOW Gold is used by mages to travel to the major cities of their faction as follows.
Portals are the warlock variation of teleportation. Rather than teleporting yourself to a location, portals pull group mates to your location. Warlocks gain the summoning ability at level 20.
Portals require the help of two other people and a soul shard. Portals can also be used outside of instances at the Meeting Stone. One player targets within the group who they wish to summon then they click on the Meeting Stone.
A second person inside of the party clicks on the Meeting Stone and that player is then asked if they'd like to be summoned to that Meeting Stone.
The person who is being targeted must meet the level requirements and WoW gold for that instance (which is listed when you hover over a stone).
To activate your hearthstone, right click it; it activates a spell that takes 15 seconds to cast (so be sure you're safely out of combat and outside enemies' reach - if the hearthstone cast is interrupted, deal with the interruption and you can begin casting the hearthstone again immediately).
