Aish'vrak potion

The Aish'vrak potion is used in the preparation of a Runestone. To use it, simply pour it on a stone that you wish to prepare for drawing upon. Most gems from the treasure system that end in the base noun "stone" (Note: base nouns like "moonstone" do not count). If you see a greenish-blue mist rise from the stone, it has successfully been prepared. Each potion has exactly one dose.
