Attributes

Attributes show the strengths of a character and determine the speed at which he/she trains skills of a certain category. Every skill has a primary and secondary attribute. The formula for the speed of skill training (points per minute) is: (primary attribute + secondary attribute/2) x (1 + 0.02 x learning skill level). The attributes used to train a skill can be seen in the Attributes tab of the skill info.

Remapping

Cutting-edge neuroscience allows capsuleers to shift their natural strengths and weaknesses around between the five key cognitive areas. This technique is frequently used to facilitate a change in the direction of a capsuleer’s skill plan.

Rules concerning Neural Remapping

• Each new character will start with two free neural remaps as a virgin mind.
• You can use the neural remap feature again one year after you last used it.
• You can not have more than 15 base points in an attribute. This leads to a maximum score of 30 for any given attribute with maximum skills and the best implants available.
• You must have at least one assigned attribute point in each attribute.
• You can not save your neural remap request if you have not assigned all your attribute points.
• You can not assign less than 4 points to each attribute.
