Scale shift

Scale shift was an alteration spell that allowed a dragon to change the color of their scales to those of another type of dragon. It was a rather unpopular spell among the dragons of Toril as many of their kind drew considerable pride from their specific species.

Effects
When this spell was cast, the scales of the casting dragon shifted to those of another type of dragon within their shared classification. There was a distinct limit to this effect, as chromatic dragons could not change the hue of their scales to resemble a metallic dragon and vise versa.

While this spell did change the color of a dragon's scales, it did not alter their form in any manner. The change was fairly convincing and could disguise the dragon from the identification of casual observers and those were un-educated in the specifics of dragonology. Other dragons would seldom mis-identify one of their own who was under the effects of scale shift.
