D20 Mechanic: Prime Attributes

From Trinity Wiki
Jump to: navigation, search

In some instances, in character creation, you may be allowed to select a so-called "prime attribute." The selected ability score does not need to be one that is relevant to your class; you could, for instance, select Strength as a wizard. The prime attribute is meant to reflect upon your character's personality, rather than chosen profession. In essence, think of it as a mechanical reflection of your character's personality onto his level progression.


When you create a character, choose a single ability score, which becomes your prime attribute. Whenever your character level increases, so does your prime attribute level (essentially, simply tack on whatever abilities you gain from your prime attribute at a given level to whatever class level you just gained).

Note that some abilities granted by prime attributes mimic class features of actual classes; this is seen as a feature, not a bug, as there should be some things that can be done in more than one way.

The Prime Attributes

Select one of the following prime attributes. The selected attribute must correspond to an ability score being used in a given game.

  • Strength. The strong.
  • Dexterity. The fast.
  • Constitution. The tough.
  • Intelligence. The smart.
  • Wisdom. The dedicated.
  • Charisma. The charismatic.
  • Perception. The perceptive.
  • Luck. The lucky.
  • Faith. The faithful.
  • Education. The educated.
