Measurement

Area; Information 
Tells the caster any one of the following things about the subject: (a) its weight; (b) its measurements in all dimensions; (c) its area; (d) its volume. This spell will provide information in the native system of the caster, be that pounds, grams, or stones about the size of your head. The measurement is as precise as the caster can comprehend. 
In some settings, where other quantities are commonly measured, other measurements may be possible. At high TLs, for example, the wave-length of a color may be determined, or the frequency of a sound. The speed of a moving object or the local gravity are also quantities that could be measured in some settings.

Base cost: 1.

Item 
A different item exists for each of the above functions: an enchanted ruler for measurement, scales for weight, a lens for color, or an onyx cube for volume. The item must touch the subject.
