After the Shadow Walker monsters died, they lost all their strength and deflated like balloons, turning into balls of light that were the size of fists. Looking across the Shadow Corridor, the corpses of the monsters were strewn everywhere.
What a great haul!
This was the good thing about Main Plot Dungeons. The Boss was powerful with high drop-rate, and the small monsters were vicious, with hundreds of them spawning at once. The Shadow Walker monsters dropped items such as "Shadow Particle", "Soul Powder", and other types of channeling materials. There was even a small chance of them dropping Anti-Darkness Potions to increase their resistance against the shadows.
