Mechanized Ascension Specialist by OnixShu

Artificers who specialize in Mechanized Ascension see
themselves as both creator and creation. Unlike their
counterparts who focus on external inventions, these
innovators gradually transform their own bodies into masterpieces of engineering, replacing flesh with precision-
crafted components that channel arcane energy with unprecedented efficiency.
Through careful self-experimentation, these specialists
develop enhancements that transcend the limitations of
their natural forms—reinforced skeletal structures,
integrated tool systems, and enhanced sensory arrays. For
them, the pursuit of mechanical perfection begins with their
own transformation, making them living proof of their
technical expertise.
