Attributes in EVE affect the training time for the skills of in-game characters. Each level of the training time of a skill depends on two seperate attributes that are determind by the type of skill involved. For example, skills in the Gunnery tree depend on the attributes of Perception and Willpower. Below is a list of the five attributes, a short description of each, and a list of the skill trees and the attributes that effect them.
