PoE 2 Map modifiers play a critical role in determining the quality and quantity of loot drops. However, not all modifiers are created equal, and their effectiveness varies depending on your strategy and goals. This guide explores three of the best map modifiers—Increased Quantity, Increased Rare Monsters, and Increased Rarity—offering a breakdown of their impact on rare currency drops, when to prioritize each, and how to diversify for optimal results.

↖ Introduction 

When it comes to juicing maps in Path of Exile 2, many players wonder which modifiers offer the best returns in terms of loot quantity, rarity, and rare monster spawns. Are there diminishing returns to consider? Which modifiers provide the most value without unnecessary risk?

To answer these questions, a detailed data-driven approach was undertaken. Over the past few weeks, hundreds of maps and breaches were tested, tracking over 1.2 million items. The findings aim to provide clarity on how different modifiers stack up and which ones are worth prioritizing.

↖ Increased Quantity

Increased Quantity is, alongside item rarity, one of the easiest and most impactful map modifiers. It boosts the items dropped from monsters directly. For instance, with 100% Increased Quantity, you are likely to receive twice the loot as compared to having no modifier.

Important Notes:

• Baseline Test Results: At a baseline of 105% (with 5% Atlas passive bonus), testing with an average of 118% Increased Quantity gave me the following results:
  • 112% increase in currency drops
  • 129% increase in total item drops
• Diminishing Returns Do Not Apply: The value obtained from the stat scales in a linear fashion which is very good and useful.
• Breach Splinters Exception: For breach splinters, the drop rate was only improved by 60%. This is probably because of them having some sort of additive interaction with a +75% Breach Splinter bonus on the Atlas Tree.

With Increased Quantity, there is no argument that this is one of the best stats when it comes to maximizing loot, specifically when there are no Atlas bonuses which are aimed at certain item types.

↖ Increased Rare Monsters

The Increased Rare Monsters perk increases the spawn rate of monsters which usually drop valueable items like rare and unique gear or high tier currency. 

Important Notes

Testing Data: We took a sample size of ~52K monsters with a mean value of 143% Increased Rare Monsters: 

• Breach Splinters: Examination revealed with increased spawn percentages, there was only a 5% rise suggesting rare monsters are of little value in these drops. 
• Low Tier Currency: Noted a moderate increase of 31% per 100%. 
• High Tier Currency: Noted a 62% increase per 100%. 
• Rare and Unique Items: Noted was an increase of 52% and 55% respectively. 

For players aiming at targeting high tier currency and rare/unique items, Increased Rare Monsters is a fantastic option, though with Breach Splinters, the impact is non existent.

↖ Increased Rarity

Having Rarity Increased will always be useful for finding rare or unique items, since it improves the quality of items dropped. The increase in effectiveness will be negated if other sources of Rarity bonuses are already high.

Important Notes:

Observations of Player Rarity in comparison with Area Rarity: Even with having 206% Player Rarity, there was an effect called diminishing returns while putting more Rarity into the system. For instance:

• Having 0% to 100: Player Rarity increased 66% of rare currency drops.

Area Rarity Observations: Based off a sample population of approximately 51,000 monsters and normalized to 100% Area Rarity:

• Since the amount of players with Player Rarity were so high, currency was collected less and increased by only 15%.
• There was a 67% and 47% increase in unidentified Tier 2-5 items and unique items, respectively.

It is most useful to use Increased Rarity from lower or zero Rarity bonuses. As those bonuses get higher, its used becomes limited in comparison to Increased Quantity or Increased Rare Monsters.
