Skill Gems are the heart of your character's abilities in Path of Exile 2. They come in three colors: Red (Strength), Green (Dexterity), and Blue (Intelligence). Active Skill Gems grant you abilities, while Support Skill Gems modify those abilities. To benefit from a Support Gem, it must be linked to an Active Skill Gem within an item's sockets. The more links an item has, the more Support Gems you can apply to a single Active Skill, dramatically increasing its power. Experiment with different combinations!
