Focal stone (spell)

Focal stone was an alteration/transmutation spell that transformed the structure of a clear or translucent gem stone, enabling it to receive the dweomer of a spell.

Effects
When cast, the gemstone would glow internally, radiating a faint dweomer. It could then be used as a focal stone or receive the life force from a magic jar spell. If it were then submerged in a poisonous liquid, it turn a vibrant purple color and could be commanded by touch to neutralize poison.

Usage
The ancient gold dragon Valamaradace used this spell, along with abeyance and multiple castings of greater levitate to keep her private sanctuary, the earthmote known as the Floating Mountain, aloft in the skies over the North.

Components
The material component for this spell was a pinch of opal dust.
