Lunar Home Teleport is a teleport spell which provided players with a free transport to Lunar Isle, teleporting them just south of the bank. This was a useful teleport, in any instance players needed to switch from the Lunar spellbook without the use of Moonclan teleport runes. It took around 10 seconds to cast the spell, and importantly, this could be interrupted at any time by combat, and only could be cast 10 seconds or more after combat had ended (similar to logging out).
The Home Teleport spell, initially designed to help players who were stuck, has been slightly changed. If you have the Ancient or Lunar spellbook and cast the spell - when on a free world - you will now be teleported to Lumbridge. When you return to a members' world, these will teleport you to Edgeville or Lunar Isle.
