Map Farming Strategy

Mercenaries of Trarthus 3.26

Last Updated:June 21, 2025|Changelog|FAQ

The Map Farming Strategy is a low investment farming method that focuses on producing the maximum amount of Tier 17 Maps, 8-Mod Corrupted Maps and Memory influenced Maps. While Tier 17 Maps typically yield the most maps due to the "More Maps" modifier tied to certain map mods, they cannot drop other Tier 17s by default.

In Mercenaries of Trarthus, using Originator-influenced maps allows the "More Maps" modifier to apply while still enabling Tier 17 drops. This interaction results in the most efficient and profitable strategy for generating maps currently available.

Set-Up

Pro Tip

When setting up to run this strategy, it is recommended that you purchase enough materials to complete a sizable batch of maps. Failing to do this makes selling your drops far more difficult, as you frequently need to interrupt farming to trade for additional supplies.

Map Choice

  • Tier 16 Dunes Map with Originator Influence
    • Dunes is the best map for the map farming strategy as it is a very open layout with easy access to the boss. This allows you to defeat the boss immediately to remove the boss modifiers from Eldritch Altars. This makes it more likely that you see "Maps have a chance to be Duplicated."
    • If you can, run the 8-Mod Originator Influence maps that you drop which have at least a 100% "More Maps" modifier.
      • If these are too difficult, you can sell them and roll your own maps for 100%+ More Maps.
    • Fortress Map is the Tier 17 that drops from Dunes. This is typically the most sought after Tier 17.

Map Device

  • Kirac Modifier - Domination.
  • Influence - Searing Exarch.
    • Searing Exarch is the preferred influence for map farming due to Wrath of the Cosmos. The key distinction between Searing Exarch and Eater of Worlds is the following:
      • Wrath of the Cosmos causes you to spawn an additional modifier 50% of the time, making the "Map Duplication" modifier more common.
      • Eldritch Gaze causes the modifier to have a 50% higher value.
    • Since Tier 17 maps have diminishing returns on their drop rate within a zone, it's more efficient to have more frequent, slightly weaker modifiers, making Searing Exarch the superior choice.

Gameplay

  • Rush to the Boss immediately and defeat it. This removes all boss related Eldritch Modifiers from Altars.
  • Clear the Map as usual saving any Petal Modifiers for large packs of blue mobs. The best Petal Modifiers are:
    • Memory of Disbelief: Consumes Petals to cause affected nearby monsters to not be able to drop items that can have rarity. The number of Petals consumed is proportional to the Power of affected monsters. (Cost 30 Petals)
    • Memory of Suspicion: Consumes Petals to cause affected nearby normal monsters to have a chance to be upgraded to magic or rare rarity. (Cost 30 Petals)
    • Memory of Panic: Consumes Petals to cause affected monsters to revive on death, dropping loot and granting experience again. The number of Petals consumed is proportional to the Power of affected monsters. Does not affect Unique monsters. (Cost 30 Petals)
