The ability to make the tablet is unlocked with rank 4 reputation in the Worker district. It may then be made from 1 soft clay and 2 law runes at any lectern in a Player-owned house. No Magic experience is gained from making the tablet. There are no requirements to use the tablet - they may be bought and used even without the reputation required to make them. The teleport tablet can be placed in the pocket slot. The teleport option on the Menaphos journal allows the use of the teleport tablet, even if the tablet is in the bank at the time.
