The Light Reflection Phase was the beginning of the first great divide amongst cultivators. This was all due to its significance as the last Foundational Stage of the Astral Core Realm. Much like the Soul Idol and Spatial Resonance Phases, the Light Reflection Phase was divided into nine outcomes.
Prior to reaching this phase, a cultivator must first absorb ambient light energies into themselves. These light energies were mostly inactive, having no legitimate uses unless a cultivator used light-attributed techniques or spells. The quality of the innate light energies in your body determines your level.
Unlike the other tribulations, this one, the Light Conjuring Astral Tribulation, was instant.
