Path of Exile 2 Catalysts: A Comprehensive Guide

Catalysts are a cornerstone of endgame optimization in Path of Exile 2 (PoE 2), offering targeted enhancements for rings and amulets. This guide covers everything from farming strategies to advanced crafting techniques, ensuring you maximize their potential.

What Are Catalysts?

Catalysts are specialized quality currency that boost specific modifiers on rings and amulets. Unlike generic quality items (e.g., Blacksmith’s Whetstones), Catalysts only enhance modifiers aligned with their designated category. For example:

• Tul’s Catalyst amplifies Cold modifiers like +% Cold Damage or Cold Resistance.

• Flesh Catalyst strengthens Life modifiers such as +Maximum Life or Life Regeneration.

• Breach Rings, a unique variant of jewelry, can achieve up to 50% Quality with Catalysts (vs. 20% for standard rings), making them the most powerful candidates for optimization.

How to Farm Catalysts

1. Breach Mechanics

Catalysts primarily drop from Breach encounters, a high-risk/high-reward endgame activity. Here’s how to maximize your yield:

Breach Basics

• Spawn Mechanics: Breaches appear randomly in the Atlas or via Precursor Tablets. Look for a purple hand emerging from the ground to start the encounter.

• Objective: Kill monsters rapidly to expand the Breach’s radius. Faster clears = more loot.

• Key Targets:

  • Clasped Hands: Interact with these to loot raw currency (e.g., Divine Orbs) and Catalysts.

  • Rare Monsters: Prioritize these—they have a higher Catalyst drop rate but require focused DPS to defeat.
    

Optimizing Breach Runs

Build Recommendations:

• Use AoE-focused skills like Lightning Arrow or Spark to clear mobs efficiently.

• Equip Pierce, Chain, or Fork Support Gems for off-screen kills.

Atlas Passive Tree:

• Crumbling Walls: Spawns multiple Breaches per map.

• Frantic Invasion: Increases Breach Splinter drops (used to craft Breachstones).

• Xesht's Madness: Grants Catalysts a chance to drop in stacks of 10 but adds the Soul Eater modifier to rares (high risk/reward).

Map Modifiers:

• Roll maps with +% Increased Quantity of Items and +% Pack Size to boost monster density.

Using Catalysts Effectively

Step 1: Identify Modifier Tags

Catalysts enhance modifiers based on their hidden tags, which are not visible in-game. Use third-party tools like poe2db to check tags:

• Visit poe2db.com/rings or poe2db.com/amulets.

• Search for your modifier (e.g., Leech #% of Physical Attack Damage as Life).

• Check its tags (e.g., Life, Physical, Attack) to determine compatible Catalysts.

Example:

A ring with +12% Cold Damage and +30 Intelligence:

• Tul’s Catalyst boosts Cold Damage (Cold tag) but ignores Intelligence (Attribute tag).

• Adaptive Catalyst enhances Intelligence but replaces existing Catalyst effects.
  

Step 2: Apply Catalysts

Select a High-Value Base:

Prioritize Breach Rings (50% Quality cap) or jewelry with 2-3 modifiers of the same type. Example: A Breach Ring with Cold Damage, Cold Resistance, and Life pairs well with Tul’s Catalyst and Flesh Catalyst.

Apply the Catalyst:

Open your inventory, right-click the Catalyst, then left-click the jewelry.

Replacing Catalysts:

Use a new Catalyst to overwrite existing Quality effects (e.g., swap Flesh Catalyst for Adaptive Catalyst).

Catalyst Types & Modifier Categories

Advanced Strategies

1. Breach Ring Optimization

Breach Rings can achieve 50% Quality, allowing modifiers to reach 150% of their base values. For example:

• A Breach Ring with +10% Cold Damage becomes +15% Cold Damage at 50% Quality with Tul’s Catalyst.

Pair with Catalyst Stacking:

Use multiple Catalysts on the same ring for hybrid builds (e.g., Flesh Catalyst + Reaver Catalyst for Life and Attack modifiers).

2. Hybrid Modifier Synergy

Some modifiers have multiple tags, enabling synergy with multiple Catalysts:

• Leech #% of Physical Attack Damage as Life:

  • Tags: Life, Physical, Attack → Compatible with Flesh, Uul-Netol’s, or Reaver Catalyst.

Strategy:

Use Flesh Catalyst if the ring has other Life modifiers.

3. Loot Filter Setup

Configure loot filters (e.g., FilterBlade) to highlight:

• Breach Rings and high-tier Catalysts (e.g., Xoph’s Catalyst).

• Avoid strict filters—Catalysts are often hidden in semi-strict settings.

Frequently Asked Questions

Q: Can I remove a Catalyst once applied?

A: No—applying a new Catalyst overwrites the previous effect. Plan your enhancements carefully.

Q: How many Catalysts do I need for 50% Quality?

A: Breach Rings require 25-50 Catalysts (1-2% Quality each). Standard rings cap at 20% (10-20 Catalysts).

Q: Are Catalysts tradeable?

A: Yes! Use the Currency Exchange at Alva’s Hideout to buy/sell in bulk.

Conclusion

Mastering Catalysts in PoE 2 requires a blend of efficient Breach farming, strategic modifier tagging, and synergy exploitation.
