The Teleport to house (chipped) tablet is a quest item unlocked in the Love Story quest. The player can obtain it by using a chisel on a teleport to house tablet, requiring 77 Magic. However, before it can be used, the player needs to solve a puzzle to obtain the complete version. This is done by opening the tablet up and manually modifying its core to allow it to travel to the Wise Old Man's old house.
When using a chisel on a chipped Teleport to house tablet, it can be modified back to Teleport to house tablet.
It is possible to keep the tab after the quest. You can make 2 before fighting Zenevivia and keep 1 for yourself. This gains nothing but having a souvenir. This can also be turned back into a normal 'Teleport to House' tab (Using a chisel).
