=== Known creation chances Creation ===Quality A dioptra is a somewhat difficult item to make. Assuming you use a [[protractor]] of about equal quality to your blacksmithing skill it can be created with as low as 30 skill in blacksmithing. It is recommended to improve the protractor first before you try to create it in order to increase the success rate. The quality of protractor affects creation chance.
* The dioptra uses 0.025 kgs of [[bronze lump]] to improve.
* A starter [[compass]] may be be used in the creation.
*90 blacksmithing skill, 14ql protractor gives 29% chance
*66 blacksmithing skill, 14ql protractor gives 16% chance
*42 blacksmithing skill, 42ql protractor gives 25% chance
*31.9 blacksmithing skill, 18ql protractor gives 6% chance
=== Notes ===
*Quality of dioptra affects how long the planed bridge may be.
*The maximum distance in metres between planner and helper is quality x 1.6, as an approximation for the number of tiles it is quality x 0.4, but as its almost impossible to stand on the tile borders its best to add 1-2 quality
*The dioptra has a relatively high value and is worth the same as, for example, mooring ropes and door locks of equal quality. [[Get price]] = QL^2 * 0.50.
== Usage ==A [[dioptra]] is utilized by activating it and right-clicking another player holding a [[range pole]]. There will be a 'Plan Bridge' option which will proceed to plan the bridge with automatic event log messages as follows: You carefully place the dioptra on its tripod in front of you. You make sure the dioptra is level. You point the dioptra at <Player>. You wave at <Player>. You line up the dioptra with <Player>. You look through the dioptra. You focus on the range pole. You read the graduations on the range pole and work out the height difference. You check the heights of the plan ends. You appear to be <xx> dirt <Higher/lower> than <Player>. You work out the orientation and width for the bridge. You check for clearance between the bridge ends. You check for protruding foliage. You check for nearby cave entrances. You check for any items in the way. You check that you have permissions to build the bridge. You check for any bridges that may interfere with this bridge. You check there would be no buildings under this bridge. You work out the styles of bridges that would fit. You start working out the bridge components required. Planned bridge area is <x> tile(s) long and <x> tile(s) wide. You stop surveying. You pack up the dioptra.Should there be any reason why the bridge can not be planned, it will interrupt the sequence with the appropriate message. ==See also===
