Teleportation Focus

You choose an object and mark it with a memory of the place you are located when the spell is cast. At the time of casting, you can also cause a phrase or symbol to be permanently engraved on the object covering an area no larger than six inches on a side. If a marked object is held whilst casting the Teleport spell, the object counts as an 'associated object' for the purpose of familiarity, allowing you to teleport without error to the location where the spell was originally cast. The mark lasts until Dispelled
