Dragon scales (Tiamatan spell)

Dragon scales was a divine alteration spell used only by specialty priests devoted to Tiamat called Wyrmkeepers.

Effects
This spell protected the wyrmkeeper by causing dragon scale plating to grow from their skin, covering their entire body except their head. The wyrmkeeper was able to choose the color of the scales from any chromatic dragon species, but the protection they offered was not determined by the color.

Components
In addition to verbal and somatic components, this spell required as material components the priest's holy symbol and a single dragon scale to cast.
