Home Teleport is a teleport spell found on all spell books, that requires no runes or Magic level to cast.
Casting the Home Teleport spell will allow the user to teleport to any of a network of lodestones scattered across Gilienor via the Lodestone Network interface. The map will have several icons representing the 22 different locations. Hovering over the icons will tell you where the icon will take you. Once you have decided upon where you want to teleport, click the icon and the map will close and activate the Home Teleport animation.
The Home Teleport is a ritual, rather than a spell, as it takes some time to cast and will be interrupted by any other actions or combat. Because of this it is not recommended as an escape teleport. In addition, most of the lodestones are placed away from major locations, so other teleports tend to be more convenient.
Note that lodestones are not all unlocked by default, the vast majority must be found and activated (by clicking on them), or unlocked by completing quests, before they can be used. New players will have their Burthorpe lodestone already unlocked. The Lumbridge lodestone will become automatically activated when going through the path system section of the tutorial.
By default both the Lumbridge and Burthorpe lodestones are unlocked. Others must be visited manually to unlock them, or unlocked via the completion of a quest.
Note that the lodestone interface will not show if you have either the tutorial active and have not yet completed it.
