Infusion

Mursaat are nearly untouchable when you first encounter them--not because you can't damage them, but because you can't live long enough to touch them! Their Spectral Agony attack can bring down the toughest of heroes in seconds. Fortunately, there is a method to protect you from this devastating skill: Infusion.

Infusion is the process of imbuing a set of armor with magic that shields against Spectral Agony. An armor with this magic is said to be "infused." All armor can be infused. When a Mursaat's Spectral Agony attack strikes a piece of infused armor, the damage is greatly reduced (click on Spectral Agony above for details).

To get your armor infused, you must seek out a Seer and give it the Spectral Essence of an Eidolon. This is first explained in the Iron Mines of Moladune mission. The Seer will inform you about the location of the Eidolon and ask you to slay it and bring back its essence. This same process is repeated at a few other locations (see below). The Seer, once given the essence, will then infuse the currently-worn armor set of everyone member in the party who speaks to it.

Note: Because the Spectral Essence is an item a party member has to carry in their hands (and not in the inventory), it cannot be transported from one place to another. So, everytime you want to get infused you will have to find a Seer and an Eidolon to kill.

Tips

 * 1) Infuse every piece of armor you want to wear! Aside from the missions, there are Mursaat in many explorable areas in the Southern Shiverpeaks and the Ring of Fire Islands.
 * 2) If you keep multiple sets of armor, or if you change your armor later in the game, you must come back and infuse the new set to survive against the Mursaat. No armor in the game is pre-infused not even the most expensive ones.
 * 3) Only armor you are wearing when talking to the seer is infused, unworn items in the inventory will not get infused. Make sure you have the right pieces equipped.
 * 4) Thunderhead Keep is the first outpost where Henchmen have infused armor too.

Other infusion locations

 * There is a seer in the north-easternmost section of Mineral Springs that will infuse your armor. The Ediolon in that area is right next to it and is called an Ice Beast.
 * There is a seer in the Ring of Fire (Mission) that will infuse your armor, see mission for details.
 * There is a seer in the Abaddon's Mouth (Mission) that will infuse your armor, see mission for details.
