Infusion

Infusion is the process of imbuing a set of armor with magic that shields against Spectral Agony, used by the Mursaat. 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.

To get your armor infused, you must seek out a Seer and give it the Spectral Essence of an Eidolon or Ice Beast. 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 every 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 via map travel from one place to another. So, every time you want to get infused you will have to find a Seer and an Eidolon to kill.

Tips

 * 1) Infuse each piece of armor you want to wear! Aside from the missions, there are Mursaat in many explorable areas in the Southern Shiverpeaks.
 * 2) If you keep multiple sets of armor, or change your armor later in the game, you must come back and infuse the new set to survive against the Mursaat.  None of the armors in the game start infused, not even the most expensive ones.
 * 3) Only armor you are wearing when talking to the seer is infused.. Items in your inventory will not get infused.  Make sure you have the correct pieces equipped.  Note: If you are wearing fully infused armor when the essence is GIVEN to the seer, you will not be able to change armor for infusion.
 * 4) Thunderhead Keep is the first outpost where Henchmen start with infused armor.
 * 5) When the seer infuses your armor, your henchmen's armor will be infused as well.  This is usually only relevant for the Iron Mines of Moladune mission.  (This was changed during the 1/26/06 update.)
 * 6) If you have access to several heroes, it can make missions with Mursaat much easier, especially with barrage/pet ranger heroes. Heroes and pets are considered infused when affected by Spectral Agony.

Other infusion locations

 * There is a seer in the north-easternmost section of Mineral Springs that will infuse your armor. The Eidolon in that area is right before you reach the Seer and is called an Ice Beast. You will have to defeat it and several Ice Imps and a Siege Ice Golem to reach him.
 * There is a seer in the Ring of Fire (Mission) that will infuse your armor, see mission (bonus) for details.
 * There is a seer in the Abaddon's Mouth (Mission) that will infuse your armor, see mission for details.
