The Yanille tablet is a modified house tablet that is created by using a chisel on a normal Teleport to house tablet. Once you break it, it teleports you to just outside the Yanille house portal. The quest Love Story must be completed to make this item. When the hard task set of the Ardougne Tasks is completed, Watchtower Teleport can be toggled to teleport to inside Yanille walls and just a little bit east of the portal.
