The Setting, story elements, and Game Master adjust what Features are relevant and/or appropriate as well as ongoing upkeep/refresher time or costs.
Flat Cost: The Essence or CP cost is a one time adjustment, done at the time the Feature is acquired.
> Inherent by Species: The Feature is gained as part of a species profile (any initial cost is built into that cost).
= Most often used for Traits.
Minor Cost: Minor Cost is scaled, typically a simple cost equal to the difference in value between measures (e.g. a 4 levels/measures = 1+1+1+1 = 4).
= Most often used for Skills and Traits.
Major Cost: Major Cost is scaled, typically an exponential cost equal to the difference in value between measures (e.g. 4 levels/measures = 1+2+3+4 = 10).
= Most often used for Skills.
Significant Cost: This is a scaled cost, typically an exponential cost equal to the difference in value between measures that is usually double the major cost scale (e.g. 4 levels/measures = 2+4+6+8 = 20).
= Most often used for special Skills and powers.
