Corrupted Mementos are a new currency introduced in Patch 8.3 to research through the Titan Research Archive and purchase cosmetic rewards from Wrathion.


What are Corrupted Mementos?

Corrupted Mementos Icon Corrupted Mementos are a new currency awarded to players in Patch 8.3 that is used in the Titan Research Archive to research new passive effects to aid in Horrific Visions.


How do you earn Corrupted Mementos?

This currency can be earnt in a number of ways, but their primary source comes from Horrific Visions.


Horrific Visions

Players will receive huge amounts of Corrupted Mementos as they manage to progress further through Horrific Visions, with a full clear with 5 Faceless Masks active granting upwards of 5,000 Mementos.

You will receive Corrupted Mementos for almost every action that you take in Horrific Visions, including:

  • Completing objectives in different zones (this is given through the chests at the end of the run).
  • Killing enemies (this is given in real time and can be tracked via the objective tab).
  • Looting chests (this is also given in real time, just as Mementos for kills are).

It is worth noting that for every Faceless Mask you have active, you will gain 20% increased Corrupted Mementos Icon Corrupted Mementos.


Completing Objectives in Horrific Visions

There are 3 types of zone in Horrific Visions and each one grants a different amount of Mementos, based on the difficulty of the zone.

For the Tainted area, which is the easiest of the three types, you will always receive a minimum of 50 Corrupted Mementos Icon Corrupted Mementos, regardless of whether you kill the boss or not.

If you do manage to kill the main boss in the Tainted area, you will receive a minimum of 100 Corrupted Mementos Icon Corrupted Mementos. You will then receive additional Mementos depending on the objectives you have completed elsewhere in the Horrific Vision. Note that this is independent of the chests for the other zones; this means that, if you clear 1 Corrupted (Tier 2) zone and then kill the final boss, you will receive a chest with 150 Corrupted Mementos Icon Corrupted Mementos for the Tier 2 objective, as well as additional Mementos in the main chest that are added on to the 100 you would get for killing Alleria or Thrall.


Killing Enemies in Horrific Visions

The enemies that you kill in Horrific Visions will give you Mementos, which you can track in the objectives tab. The amount you receive for kills is updated in real time, meaning the amount you receive is immediately updated in the objective display.

You will receive the Mementos that are displayed here once you leave the Horrific Vision, rather than in a chest, as with the objective Mementos.


Looting Chests in Horrific Visions

Once you have researched Clear Sight Icon Clear Sight in the Titan Research Archive, you can find chests in Horrific Visions that grant additional Mementos.

You will get more from each chest as the difficulty of the zone increases, with Tainted areas giving the least and Lost areas giving the most.



You can earn small amounts of Mementos from Assaults, most notably from the cache that you get after completing an Assault and handing it in.

You can also have Mementos drop from mobs in Assaults, but the amounts are normally fairly low.


Visions of N'Zoth

The daily Visions can also give players Mementos, both through completion and kills. While you normally will not get a huge amount of Mementos from kills, once your cloak is upgraded and you are well enough geared, you can very easily mass pull mobs inside the Visions to farm up a decent amount of Mementos.
