Mirtokh potion

This is an enchanting potion commonly used for advancing the enchant of an item from 6x to 7x. Each bottle contains either 4 or 5 doses, depending on the location of its purchase.

It is commonly available at the town alchemist shop in most major towns, and is sometimes used for lower level enchants as well.

At the 2007 Winter Festival outside Icemule Trace, indigo and violet striped jugs were sold which contained 20 doses. Unlike standard enchanting potion bottles, these jugs do not shatter when empty, and can be refilled (but only to approximately 8 doses).
