The use of skills is crucial to surviving in the world of Wraeclast. Skills in Path of Exile fall into two main categories: active skills and passive skills. There are no class restrictions on what skills can be used so any class can use any skill (passive and active). Each skill is linked to one of the three attributes, however, meaning that different character classes will favor skills associated with that class's dominant attribute(s).
Passive skills require no special action from the player to provide a benefit. They may inlude effects such as always-on buffs, or enhancements to various types of actions that occur automatically.
Passive skills are acquired by spending skill points. When a point is spent on a skill, the character also receives a permanent bonus to that skill's attribute. The amount of this attribute bonus depends on the character's class.
Active skills must be used or cast to have an effect, such as spells and special attacks or maneuvers. Characters gain access to active skills by equiping items socketed with skill gems(We can get gems from third party websites, such as we can buy POE currency online). These skill gems gain experience while equipped, becoming more powerful as they level up. Active skills may be assigned to the right and center mouse buttons as well as the Q, W, E, R, and T keys.
Skill gems may be augmented by support gems, which change their behaviour or add additional functionality, such as increasing the speed of projectiles launched by the skill, or increasing its area of effect.
