Duality Domain

In the realm of faith, there exists a domain unlike any other, a sacred union of two deities' souls sharing a singular divine body. The Duality domain, deeply rooted in the legends of the tempestuous Arahan and the serene Naestra, known mostly as the sisters of twillight, the inseparable sisters, brings forth a unique blend of courage and serenity, might and tranquility, psionic force and psychic mastery.

Duality domain clerics are usually lovers, brothers, sisters or anyone with a bond tight enough to bind their fate together, come hell or high water. Most clerics of the duality domain are usually paired off as two, this way with each of the paired cleric following one of the twillight sister's path while the other one follows the other sister's path. Just like the twillight sister's themselves, these paths are usually conflicting and often contradictory. This is also reflected on the clerics of each path themselves. The duality domain focuses on love, devotion, tolerance and loyalty between two people with a bond that would often transcend death itself despite having very conflicting personalities, morals and way of life. A faith where you put every trust you have in your bonded and expect them to do the same. But usually, the most favoured of these clerics are they that share the twin soul aspect of the sisters of twillight by having two souls inside them, able to change the dominant soul inside their vessel with some effort. These clerics are able to harness and utilize both the gentle whip of psychic energy and the violent and powerful hammer that is psionic energy.

Note: This is originally made for my dual soul PC and I know this domain is filled to the brim with features. Don't expect much balancing from me, feel free to change or reflavour things to suit your game though. I'll fix the domain spell list someday to correspond to the level, but just try to only use spells that you're supposed to get. Cheers!
