Skill gem

Active Skills are abilities which an exile activates by using an equipped Skill Gem, they are controlled by mouse or keyboard events. They take mana and grant an immediate effect. They are not Passive Skills, constant effects which are mainly earned through character levelling.

Gems

All Active Skills are contained in portable gems which must be equipped in gem sockets before their use. Support Gems augment these skills when the gems are linked.

Gem Experience

Gems gain experience and levels alongside the character wearing them. For all the experience the exile receives, a gem gains its own additional experience at 10% of that amount. Additional gems do not share that experience, but gain their own 10%. Gem experience is not restricted by player level boundaries, so a high level characters might not gain experience from low level enemies, but the gem will continue to gain the 10% it normally would. Gems do not need to be utilized for them to gain experience, only equipped. Gems equipped in both weapons slots gain experience, though only the currently active weapon slot's skills can be used.

Once a gem has enough experience to level up, it will stop gaining experience and a level-up icon will appear on the right of the screen and in the inventory menu. Left-clicking it will level up the gem, right-clicking the icon will hide it on the side of the screen, but it will still be accessible in the inventory menu. Not levelling up a gem is useful in some situations.

As gems level up, the abilities they grant get better, but the requirements to equip them also increase. Each gem level, the exile must have both the attribute corresponding to gem colour and a character level high enough to meet its increased requirements. If a gem gains enough experience to level up, but the exile currently does not meet the requirements, the level-up icon will appear greyed out and not be useable until the requirements are met. For specifics, see the lists of Active Skills and Support Gems below.

Gems may be traded like normal items and they will retain their experience.

Sockets

Each gem must be set in a socket corresponding to the gem's colour. Sockets can be found in Armour and Weapons and can hold either Active Skill Gems or Support Gems.

Orbs can modify the sockets in items. Chromatic Orb - Reforges the colour of sockets on an item. Jeweller's Orb - Reforges the number of sockets on an item. Orb of Fusing - Reforges the links between sockets on an item.

The random choice of colour for sockets is weighted upon which attributes are required to use it. Gear that requires Strength has a big chance to obtain red sockets. Likewise, Dexterity with green ones, and Intelligence for blue. If gear has two requirements, both colours generate with increased chance. This is also true for any Chromatic Orb / Jeweller`s Orb reforging.

Support Gems are gems which modify the Active Skills they are linked to. To link Support Gems to Active Skill gems, they all need to be socketed in a segment of sockets which have lines between them. Many linked sockets can be used to give many skills a number of support bonuses. For example, the two skills Fireball and Freezing Pulse may be linked with the support skill Elemental Proliferation in a three linked item, or Freezing Pulse may be replaced by Chance to Ignite to enhance the Fireball even more. This is why rare maximum of "6l" or six-linked-socket items are so powerful, they can link up to 5 Support Gems to 1 Active Skill.

Helmets, Gloves, Boots can have up to 4 gems; Chest armor up to 6; Two-handed weapons up to 6; One-handed and Shields up to 3.

The item level required for a number of sockets is:

Number of sockets	Minimum item level	First vendor
2	1	Normal, Act 1
3	15	Normal, Act 1
4	28	Normal, Act 3
5	35	Cruel, Act 1
6	50	Cruel, Act 3

Starting weapons are an exception; they are item level 1 with 3 sockets.
