Amulet of supremacy

An amulet of supremacy was an extremely rare type of magical amulet that was only worn by dragons of Toril. It was immensely powerful piece of jewelry and was considered priceless among their species.

Description
A masterpiece of draconic craftsmanship, this amulet was made from the purest strains of metal and was adorned with flawless gems that shone with the utmost brilliance.

Effects
When worn, the amulet maximized the natural powers and spellcasting abilities of a dragon. It increased the destructive potential of the dragon's breath weapon and extended the duration, area of effect and damage of the spells they cast to their highest capabilities.

Any being other than a dragon who attempted to wear an amulet of supremacy died instantly, typically by immolation or disintegration.

Creation
Only the oldest dragons, who possessed the highest levels of arcane power were capable of crafting an amulet of supremacy. As such, only a handful of them have appeared throughout the history of the Realms.
