== Description ==
''An astronomical and surveying instrument, mounted on a tripod.''
== Notes ==
*A Dioptra is very a somewhat difficult item to make and will need . Assuming you use a decent [[sight]] of about equal quality materials and to your blacksmithing skill it can be created with as low as 30 blacksmithing skill. It is always recommended to improve the sight and protractor first before you try to create themit.*The protractor affects the unfinished Dioptra quality and ultimately the finished quality.
*Quality of Dioptra affects how long you can plan a bridge.
*Starter compass can be used.
*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.
