Attribute

Every character and every creature in the Space Truckers universe is assigned attributes. These attributes (Strength, Agility, Constitution, Intelligence, Wisdom and Charisma) affect just about every dice roll in the game. The higher the attribute, the greater the modifier associated with this attribute. Character attributes are often changed by racial traits.

General Rules
A character generally assigns attribute values by rolling 4 D6 dice and adding up the top three values. This is repeated six times and then the values are distributed amongst attributes. The values are then modified based on racial traits, etc.

Attribute scores may be changed, either permanently or temporarily, during the course of the game by the following things:
 * Every character gains 1 point to spend in attributes as s/he levels up to the 4th, 12th, 16th, 20th, etc. levels.
 * Some psionic and tech abilities can reduce or improve attribute scores
 * Several items increase attributes, such as stimulants
 * Some poisons and diseases can affect attribute scores
 * As a character ages, some attribute scores are improved while others are reduced

Attribute Modifiers
The effect an attribute has on various game mechanics is quantified by the attribute modifier. The modifier of an attribute is determined by applying one of the following formulae to the attribute value: Thus the relationship between values and modifiers is represented in the following table.
 * If the attribute value is even, modifier = 0.5*(n-10), where n is the attribute value
 * If the attribute value is odd, modifier = 0.5*(n-11), where n is the attribute value
