This approach to using the d20 variant for Incarna uses a great deal of extra rules on top of the existing Essential Approach rule changes and the d20 system itself. The Aptitude Approach for the d20 Incarna variant is considered an Advanced concept. It add a lot of Incarna specific mechanics and options that may impact the balance, play, and time spent on the game.

Alternate Take: Allotted Essence

To avoid using the full Aptitude system but maintain the iVerse flavor and context, use “Allotted” Essence. This is Essence offered up permanently to achieve familiarity in the noted function. Example: 5 [Occult] Allotted Essence means the character must have sacrificed 5 Essence towards Occult familiarity.

Characters must assign a Primary Class if they have not already (they may only possess 1); this must be the highest or tied for highest Class Level. This class must be one in which they have a starting level in.
