Platinum dragon scale
Platinum dragon scales were once one-off artefacts which were been put up for auction at various times. Drawn from the Greater Dragon Atanamir himself, the scales are said to be imbued with the power of Light and Righteousness, reducing a Priest or Paladin's devotion usage by 50%. They were won by Liliana in 531 AF and by Silvarien in 634 AF but were eventually duplicated and opened for sale to the general populace by Merentesh at the Class Artefacts Shop: Magi - Sentinel in Delos.
