The aish'vrak potion is used to prepare stones to have runes drawn upon them. To use, pour it on the stone you wish to prepare. Only items with "stone" as their complete noun can be used in this way (a "moonstone" would not suffice). A successful pour will cause a "greenish-blue mist" to rise from the stone.
Crystal core essence cannot be made until rank 15.
