Eagle-vision

The eagle-vision spell has two possible manifestations, either of which the caster can use. The caster must specify which version will be used when memorizing the spell. The first version temporarily duplicates the effect of a 20:1 telescope, under the caster's mental control. The spell manifests itself as a slightly warped-looking piece of air in front of the caster's dominant eye. The second version reverses the magioptic field to produce a microscope with 20:1 magnification.

The material component (consumed) is a piece of optical glass worth at least 1 gp.
