Valimancer / Theurge: Because I have mastered the ancient magics of the Primal Element of Positive Energy, the raw quintessence from which all material things are formed, I may combine my Divine and Primal Archetypes when I am casting spells related to radiance (pure energy), healing, creation ex nihilo, directly opposing negative energy, and so forth.
Voidmancer / Anatheurge: Because I have mastered the ancient magics of the Primal Element of Negative Energy, the void which eventually claims all things, the null state that counterpoints existence, I may combine my Divine and Primal Archetypes when I am casting spells related to stagnation, entropy, undeath, enervation, life draining, directly opposing positive energy, and so forth.
Urban Jungle: Because I have mastered the art of fading away, blending in, and avoiding notice even in urban areas among people, I can use Primal instead of Roguish to create advantage and overcome when attempting to avoid being noticed in civilized areas (Primal is already usable for this in rural, wildland areas).
Death To Undeath: Because I have mastered the manipulation of Positive and Negative energies, when I am Sneakily Primal and attack I may spend a Fate point to target all Undead in my zone and all adjacent zones without having to split my shifts between them. Because I have the support of my goddess Pharasma, I may also add my Divine Archetype as a bonus to this attack.
