==Description==An item used to limit access to a mine''A door made from the purest silver.''

=A '''silver mine door''' is an item used to limit access to a mine. ==Usage===*Activate the mine door, right click a mine tile border and select ''build Build door''. == Maintenance == Once installed, the silver mine door slowly loses strength if off deed. To keep it from decaying, it has to be repaired. To repair the silver mine door, activate a [[silver lump]], right click the mine door and select ''Improve''. The lump does not need to be glowing hot to be used. The maximum strength you can improve a silver mine door to depends on the silver lump and your blacksmithing skill. The formula is 100 * (Lump QL / 4 + Blacksmithing skill / 2).  Each improvement uses 0.1 kg of the silver lump and raises the strength of the mine door by a fifth of the difference between current strength and maximum strength. The following graph shows the decay of a silver mine door over the course of over a year. The Mine door has been repaired a few times since.The decay has been about 28 strength per day on average over the whole period of 400 days. [[File:Silver mine door decay.png|Decay of a Silver mine door]]

* '''Mine doors cannot be placed on entrances with a slope of greater than 90.'''* '''Remember that off-deed mine doors can be bashed by other players, so your mine is not entirely safe just because it has a mine door attached. A deed [[perimeter]] does NOT protect mine doors.'''* If you wish to place a [[fence]] around a mine entrance this should be done before attaching a mine door.* On [[Elevation]] and [[Defiance]] servers, there must be a minimum of 3 tiles between mine doors and only 4 mine doors in an 11x11 area. There is a check in a 5 tile radius around the door being placed.*Right -click on the door to manage the permissions.*Need door lock.*Needs a high blacksmithing skill with a high ql QL door lockto start.*Very hard to start and continueat low skill, though there is no hard coded limit.
