Equipment Infusion

Equipment Infusion is mechanic added to TERA in level 70 patch in March/April 2019.

Dungeons, high level monsters and certain quests drop randomly blighted/rusty gear, that has low stats and is not useful to equip. However, some stats can be transferred to your gear.

"Infusion" button is added to bottom of inventory. Selecting gear piece and equipment material gives your gear random lines from blightedoath or Duranium equipment, which is consumed. Frostmetal Gear can have one line added to it, Stormcry Gear and Heroic Oath Gear can have two lines, Mythic (Kaia's Fury and Wisdom)gear has three lines. Kaia's Soul Gear also has three lines. It might take several tries to get optimal or useful rolls.

Fodder material
Fodder gear comes in various grades: Blighted, Blightrage, Blightoath and Battered Oath, latter having higher stats.
 * lowest materials are trash and should not be used Blighted and Blightrage no longer have any uses.
 * Blightoath is now the lowest, but it also has lower lines, total 6 lines.
 * Battered Oath has only four best random lines, which include 4 power, 7 crit factor, 4 endurance and 7 crit resist factor (crit resist is useless).
 * Refined Duranium Medallion Exchange is now the middle tier as of Patch v99, Information below.
 * Enhanced Duranium Medallion Exchange is currently as of Patch v99, the best in game. information below.

In patches before patch 99 some dungeons are guaranteed to drop blightoath infusion box: AQ and DAN drop weapon, AAH gloves, GVH cheast, GLSH shoes. However, this is removed in October 2020 patch. After January 2021 patch v102 closed Macellarius Catacombs even low grade infusion material is harder to find.

Guaranteed sources of Blightoath Medallion's should include Azart Hatchery and world boss Cerrus, Hazard, Ortan raids. Also Hidden Wooden/Silver Crates from dungeons seem to give these tokens. Also "winner" of world boss raid and random participant get random Battered Oath piece. ( Battered Oath also sells for if it's not worth using. )

Crafted material
Since patch v95 you can craft infusion material (Artisan in Processing, master in Smelting needed). Materials for this are Duranium Shard Fragments and Duranium Essence Crystals from Exodor. These are refined with 3 step process: (You can use partner adventures to gather these materials.)
 * Duranium Shard Fragments -> Duranium Ore -> Flawless Duranium Ore -> Glorious Duranium Ore (12&times;12&times;3 = 432)
 * Duranium Essence Crystal -> Duranium Crystal -> Flawless Duranium Crystal -> Glorious Duranium Crystal (10&times;10&times;3 = 300)

Smelting skill uses these to craft Processed Duranium Medallion. Based on patch notes this is token for material similar to Blightoath token. Critting gives Glorious Duranium Medallion which is similar to Battered Oath token.

Patch v99 added and with new style effect (amplification instead of power). Max stats seem to be 3280 amplification, 1640 resistance, 10 crit factor. If we use rule-of-thumb 1 power = 360 amplification, max amp equals more than 9 power.
