Chromatic Calibration: Retinal Armor

This achievement requires you to craft all seven Pandaria goggles and will reward the cosmetic appearances for each, even if they are a different armour type than the character crafting them. According to PTR data, the appearances will be available on all non-Engineer characters upon completion of Chromatic Calibration: Retinal Armor. This achievement can be completed on a single Engineering character, as all armor type patterns were made available in the Dragonflight prepatch. The goggles are BoE and you could try and sell them on the Auction House once you've crafted them for the achievement.

You can learn all the patterns from the Pandaria Engineering trainer [npc=55143] in Valley of the Four Winds, and you'll need Pandaria Engineering (75) to craft these items.

This achievement does not grant goggle mogs to your non-engineer characters. Doing these achievements only gives your engineers access to the colors not normally available to your armor class. I've put in tickets to Blizzard and received multiple responses saying this is as intended. It is not like the PTR Data where non-engineers got access.

Had I known this I wouldn't have spent the million gold and all the time doing these achievements.

If you are looking for an easy way to track how many of which materials you need in-game, Profession Shopping List may be for you. You can manually track recipes, or use /psl [achievement] to track all the recipes required for the linked achievement.

The addon will calculate all the necessary reagents and show you how many of them you already have. You can also Ctrl+Click any reagent that can be crafted itself (i.e. Bronze Bar) to track the recipe for that as well.

Happy crafting!
