Unique Gems and Path of Exile 2 Currency Legendary Skills
While most Skill Gems in PoE 2 will come from the standard system, there will also be unique gems tied to specific legendary items or achievements. These gems offer exclusive abilities that cannot be obtained through the regular skill gem system.

Legendary Skill Gems: These gems will be tied to powerful, endgame content and will often come with dramatic effects that alter the flow of combat. They may have unique mechanics that bypass certain restrictions, such as energy or mana cost, cooldowns, or other limitations. For instance, a Legendary Gem tied to a boss encounter might allow you to summon the boss's powers for a short time, temporarily gaining their abilities for your own use.

Boss-Specific Gems: Some of the most powerful gems in the game will be tied directly to boss drops. These gems will contain abilities or effects associated with a specific boss, creating a sense of progression as players acquire these rare and powerful gems throughout their journey.

Gem Scaling and Quality
Each gem will have a leveling system that increases its effectiveness as you progress through the game. Additionally, gems can be improved through quality, which increases the gem's power and efficacy.

Gem Quality: Quality increases the effectiveness of the skill granted by the gem, such as increasing damage, improving cast speed, or reducing mana cost. In PoE 2, there will be more ways to improve the quality of gems, either through traditional means like Gemcutter's Prisms or new methods unique to the game’s expanded crafting system.

Gem Scaling: Gems will scale with your level and your gear, ensuring that they remain relevant throughout the entire game. As you progress, you'll be able to upgrade your gems to higher tiers that unlock more potent effects or alternate forms of the skills.

Conclusion: The Heart of Combat
In Path of Exile 2, Skill Gems continue to be the heart of combat. With powerful new features like multi-class synergy, alternate gem effects, and cross-class support gems, the game offers more ways than ever for players to experiment and build creative, powerful characters. Whether you're a veteran or a newcomer, understanding and mastering Skill Gems will be a key part of your journey in PoE 2. This system offers players immense flexibility, allowing them to tailor their skills and POE2 Currency abilities to create the ultimate combat experience.
