Path of Exile 2: Support Gems & Modifiers Explained
In Path of Exile 2, support gems and Path of Exile 2 Currency modifiers remain a core part of build customization, but they’ve been significantly revamped compared to the original game. With the shift to active skills embedded directly in weapons and the expansion of support slot functionality, understanding how support gems and modifiers work is more important than ever.

Whether you're a returning exile or a newcomer to Wraeclast, this guide breaks down the basics and nuances of support gems and their modifiers in PoE 2.

What Are Support Gems?
Support Gems are special socketed gems that modify or enhance the behavior of your active skills. They don't deal damage on their own, but instead alter how your main skill works—increasing damage, adding effects like projectiles or AoEs, modifying cost, and more.

Examples:

Added Cold Damage Support – adds flat cold damage to attacks or spells.

Multistrike Support – repeats melee attacks multiple times quickly.

Chain Support – causes projectiles to chain to additional targets.

Key Change in Path of Exile 2: Skill Gems in Weapons
In PoE 2, active skill gems are socketed directly into weapons, and support slots are unlocked based on cheap POE 2 Orbs weapon type and progression. Each weapon can have multiple built-in support slots that modify the active skill.
