In Path of Exile, nearly all action RPGs had linear skill systems where the progression of an active skill was preordained by the developers. If you were a fire user, you would progress from a weak fire spout to a more powerful fireball, and eventually to something big and flashy like a flame wave.
Throughout Path of Exile, you’ll acquire many items with colored sockets that correspond to the game’s three attributes of Strength, Dexterity and Intelligence. You can socket the skill gems you find into these colored sockets to immediately gain the use of that particular skill. Each skill gem is aligned with a single attribute. For example, the Fireball skill is aligned with Intelligence, and therefore appears on a blue gem.
The color of sockets on items is strongly biased towards the attributes that the item is aligned with. For example, a Strength/Dexterity sword is very likely to contain red or green sockets and unlikely to have blue sockets. Skill gems can only be placed in a correctly colored socket.
Skill gems can be removed from sockets by right clicking on them. There is currently no penalty for doing this. We want players to experiment with the nearly infinite combinations our skill system allows.
Items can have multiple sockets, which can be different colors. Though the early items you encounter will contain one or maybe two sockets, the number will increase throughout the game. Most armor pieces can have up to four sockets. High end body armor can reach six sockets. One-hand weapons and shields cap out at three sockets, while two-hand weapons can contain six.
In Path of Exile, active skills (i.e., skills that you use on command) are itemized onto “Skill Gems”. These gems confer an active skill to the player when they are socketed into equipment and gain experience as the player slays enemies.
A choice of staple skill gems are given out as quest rewards throughout the game to ensure that players have a variety of skills available. You’ll discover rare advanced skill gems out in the wilderness and dungeons. Like all items, these can be traded between players. Some of the more devastating skills are extremely valuable.
Gems can also level up. When a player is awarded experience, all gems in equipped items gain 10% of that value. This gain is in addition to the experience earned by the player. When a gem is removed or traded, it retains its experience. It’s possible to specialize in leveling up valuable gems and trading them to other players. We haven’t announced the number of levels that gems will have, but it takes a substantial amount of experience to reach the highest levels of gem potency.
Gems have attribute requirements based on their type and level. For example, a higher level cleave skill gem requires more strength than a low level one. If your character doesn’t meet the attribute requirements of the new level of the skill gem, then the experience value sits at the maximum of the previous level until you next gain additional experience and also meet its requirements.
The above is an explanation about the sockets and skill gems. Meanwhile, we can’t ignore the fact that PoE Orbs is important in this game, you can buy PoE Orbs on Gm2v Gamer Online Store.
