With the launch of World of Warcraft: Shadowlands 9.1, countless changes have been brought to the game, among which the most interesting is the changes in legendary items. Perhaps the biggest change in legendary items in Patch 9.1 revolves around the way basic items are upgraded. In the case of only four levels of legendary items, after the first eight months of expansion, players will have the opportunity to upgrade their basic legendary items to the fifth and sixth levels. But if you want, you will need several key reagents. The most important of these reagents is Korthite Crystals, which can be found in Korthia, the latest open world area of the game. Here is all the information about Korthie Crystals and how to use them to upgrade the basic legendary items in World of Warcraft: Kingdom of Shadows. What are Korthite Crystals? Korthite Crystals are a new crafting reagent that was added to World of Warcraft with the release of patch 9.1. For now, Korthite Crystals does not seem to be of much use except as an integral part of the production process of upgrading the basic legendary items. Korthite Crystals can be obtained from various activities and objectives in Korthia, the latest area of the game. From completing tasks to destroying rare enemies, and even participating in assaults in Korthia, almost everything you do in the area has the opportunity to reward you with a Korthite Crystals. Some missions will reward you with one Korthite Crystals, while other missions will reward you with up to two. The results are usually random, so there is no fixed number on how many grams of iron ore crystals you can get in a given weekly reset. How to use Korthite Crystals Korthite Crystals are currently sold at very high prices on auction houses because they are used to craft higher-level basic legendary items. To create your 5th and 6th level legends, you need 40 Korthite Crystals. In addition, you also need some class-specific materials, such as cloth, ore, leather, and essence, in order to fully create a level five or six legend. Then you can convert your raw materials and Korthite Crystals into an item called "Origin Ruins", which can increase the level of the base legendary item by 2. If you have been trained in one of the blacksmith, jewelry making, leather making, or tailoring professions, you can make the relics of origin, because each profession has a different formula containing 40 Korthite Crystals. If you have not received training in one of these professions, you will need to purchase a pre-upgraded basic legendary item from the auction house.
