Skill gems are the foundation of a character’s abilities in PoE2. These gems grant active skills such as fireball, summon skeletons, or whirlwind attacks. Each gem can be leveled and modified with experience points, improving damage, utility, or survivability. Support gems further enhance these abilities by modifying elements like attack speed, area of effect, or damage type. For example, linking a fireball gem with a faster casting support gem can transform a standard projectile into a rapid, high-damage barrage, making combat more dynamic and responsive to different scenarios.One of the most engaging aspects of PoE2 is the interdependence between skill gems and character attributes. Strength, Dexterity, and Intelligence not only determine gem usability but also influence effectiveness. Strength-heavy characters excel with melee skills, while Dexterity supports bow and evasion builds, and Intelligence enhances spellcasting potency. Understanding this interplay allows players to maximize output while ensuring survivability, encouraging experimentation with gem combinations and attribute allocation.
