We already provided this guide for how to add special attacks to Sa[n]crosanct and Inamorata weapons by adding grey glyphs. Those faction locked weapons can be further upgraded by adding a turn spirit to increase their damage, reduce the cycle time on their special attacks, add a profession requirement and remove the Shadowlands expansion requirement, which makes these weapons also highly desired as froob end-game weapons.
What is a Turn Spirit?
There are four main ways to obtain turn spirits. The first method of obtaining turn spirits is by purchasing a Turn Spirit Flesh Pouch from a Yuttos named "Books and Manuals" or just "Manuals". You can find these Yuttos in various zones in the Shadowlands. Make sure when you buy the pouch that its QL is no less than 80% QL of your weapon. Unfortunately the turn spirit you get from the flesh pouch is completely random and the flesh pouches are very expensive.
To open the pouch, right click it. You will then have a random Turn spirit in your inventory.
The second option is to buy them from the "Superior ICC Weapon Supplies" teminal in the tradeskill department in neutral shops. This option is a lot more expensive than buying them from Yuttos; 5 times more expensive from the Advanced terminal and 10 times more expensive via the Superior terminal. The Basic terminal doesn't sell any.
The third method for obtaining a turn spirit is to loot them from the the corpses of dyna bosses in Shadowlands. Turn spirits are a rare and random drop off dyna bosses in Shadowlands.
The fourth way to obtain a turn spirit is to purchase them from other players. Since turn spirits are both profession and faction specific, when a player gets one that isn't for their profession or faction, he or she will likely be inclined to sell it rather than hold onto it.
Turn spirits can be either white or black:
White Turn Spirit
Black Turn Spirit
Which Turn Spirit should I use?
Here is a table showing which turn spirits are available for your profession, depending on your affiliation.
The final step of the tradeskill process makes the weapon NODROP. Therefore, after you get your favorite tradeskiller to combine the grey glyph and the base weapon for you, make sure you add the turn spirit to the weapon yourself.
The process requires 6 X QL of the weapon in Weapon Smithing, 5 X QL of the weapon in Electral Engineering, 4 X QL of the weapon in Field Quantum Physics when adding the grey glyphs to the Sa[n]crosanct/Inamorata weapons, but the final step of adding the turn spirit to the weapon requires no tradeskills. The Grey Glyph's QL does not matter; you may add a QL 100 Grey Glyph to a QL 300 weapon. The turn spirit needs to be at least 80% of the QL of the weapon. For example, a QL300 weapon will need a turn spirit that is QL 240 or higher. The final QL of the weapon depends on the QL of the original Sa[n]crosanct or Inamorata weapon. The QL will not bump if you have high tradeskills or add a significantly higher QL turn spirit.
The following tables show the various turn spirit weapons organized by profession and then by faction (use the Table of Contents at the top of the page to jump to your profession). Some things to remember: Inamorata weapons are for the Omni faction and Sa[n]crosant weapons are for Clan. Some of the clan weapons are named "Sacrosanct" (no 'n') while others are named "Sancrosanct". Turn spirits cannot be added to any upgraded Inamorata/Sa[n]crosanct weapon but rather only the weapons with the specific upgrades listed below. Some turn spirit weapons do not have special attacks. For instance, the Engineer pistol does not need a grey glpyh, whereas adding a turn spirit to an upgraded bow with special attacks will result in a Meta-Physicist bow will with the special attack removed. Finally, turn spirit weapons occur between QL 100 and 300, with the QL 300 weapon having a different name from the QL 100-299 weapon. The following table lists the name of both the QL 100 as well as the QL 300 weapons for your reference.
