==Distance==
Maximum measurable distance is based on item quality.
The dioptra’s effective range is calculated as: '''maxTiles = QL * 0.4 + rarity'''
This value is compared against the actual 3D distance between the dioptra user and the target, converted to tiles (meters / 4).
If 'maxTiles < distanceInTiles', the measurement fails.
