Watchtower Teleport teleports the caster to the top of the Watchtower, just outside of Yanille. Players must have completed the Watchtower quest to use this spell.
Players who have completed the hardArdougne Tasks will be able to change the teleport location to within Yanille's walls by speaking to Aleck at the hunting store.
With the release of the ability to change the Watchtower Teleport location, initially the Yanille portal in a player-owned house would not change with the spell. Now the portal location has been fixed, and anyone who uses the portal of someone who has changed their teleport location will also appear inside Yanille's city walls.
