I also have a complete set of all 3 Vexus Recipes for the following items:

• Vexus Honor Scarred Plate
  
• Vexus Royal Helm
  
• Vexus Stinger Blade
  

All three items are made only from components extracted from the Royal Carapace resource dropped by the Vexus Queen (Level 150 Super Elite) located in Ekloren (East, North, South, and West).
