Path of Exile 2 Skill Gem System — Complete Guide to Skills and Supports
Updated 2026-06-02
The Path of Exile 2 skill gem system is the foundation of every character build. Unlike the original game, the Path of Exile 2 skill gem system separates skill gems into dedicated slots with support gems occupying their own sockets. Mastering the Path of Exile 2 skill gem system lets you customize every active ability with up to five supporting modifications that change its behavior, damage type, and utility.
How skill gems work
A Path of Exile 2 skill gem grants an active ability when socketed into a weapon or armor piece with an available skill slot. Each item has a limited number of skill sockets determined by its item level and rarity. The Path of Exile 2 skill gem socket system supports linking support gems directly to the skill gem, with each link adding a modifier. A three-link setup with a Path of Exile 2 skill gem and three supports creates a powerful combination that scales through the campaign.
| Socket Type | Gem Type | Example | Max Links |
|---|---|---|---|
| Green | Dexterity | Shrapnel Blast (Crossbow) | 5 |
| Red | Strength | Sunder (Mace) | 5 |
| Blue | Intelligence | Fireball (Staff) | 5 |
| Green/Blue | Dexterity/Intelligence | Tempest Strike (Quarterstaff) | 5 |
Support gem linking
Every Path of Exile 2 skill gem can be augmented by support gems that modify its functionality. For example, linking a Path of Exile 2 skill gem like Fireball with Added Fire Damage Support and Elemental Proliferation Support makes it ignite nearby enemies. The Path of Exile 2 skill gem linking system requires the support gem to match the item socket color. Leveling a Path of Exile 2 skill gem increases its damage and unlocks higher-level support gem requirements.
The Path of Exile 2 skill gem leveling system uses experience points that the gem itself earns as you kill monsters. Gems level independently from your character, reaching maximum level at character level 90. The Path of Exile 2 skill gem system rewards experimentation, so try different combinations to discover powerful synergies.
