Infused armor, where and how to get this?

I know that people say you can get infused armor at Iron Mines of Moladune. I have completed this mission and killed Markis. I did not get my armor infused. I understand it protects against spectral agony.
Can anyone tell me where and how in this mission I can do this?
Or are there other places to get infusion done that might be easier?
Thanks for your help.

The easiest way to learn about infusing your armor is to join one of the constantly spamming Infusion Run groups that will be advertising in town. Basically it involves taking a roundabout path to the Seer on the mission map who will give you a job to do, which, once done, will allow you to pick one of your pieces of armor to become infused. Even if you don't generally like grouping with people, doing it once just to see how to get to the Seer is worth the time you'd save trying to figure it out from written directions.

Infusiong is a must do to, or you'll never servive long...

whats an infused armor?

Even though they're hard to come by, try to find a group that is willing to watch the Seer cutscene. The Seer explains that Infusion does.

In a nutshell, Mursaat love to spam Speical Agony, which could do up to 300 damage in one blow. Times that by 3 since I've never seen less Mursaat in a group. With fully Infused armor, Special Agony does about 10 damage to me.
