After carefully reviewing the restrictions and side effects of the Soul Devourer Sphere, Sterl began to understand why this treasure, which was worth as much as a radiant-level artifact or even stronger, had been left to collect dust in a corner.
First and foremost, every time the user infused soul power into themselves or their subordinates, they would bear the full brunt of the soul power's impact. If the user's soul strength was insufficient, it would be like a mud-built dam being instantly washed away by a fast-flowing river of soul power!
The consequences of soul damage were severe: either the person would lose all potential for further improvement or be reduced to a complete fool—though that was still a relatively better outcome. With worse luck, the soul could be torn apart, and the agony would last for a lifetime.
