 * Vial of Black Dragonsblood

Description
I've pinpointed Nalice to the Master's Cellar, an extended basement you'll find in the ruins up ahead.

Dragon cultists are everywhere, and Nalice has set up some strange arcane storage devices throughout the area. Perhaps you can use those to your advantage?

Rewards
You will receive:
