Some white scales

Area Oak Forest

Before starting on this trip, I recommend you to have shadowplane. Get into shadowplane the moment you reach Oak forest. Upon arriving at destination, you will run into 1 problematic mob: The malevolent kifta which sits in shadowplane. But that's the only aggro mob you have to overcome. Those without shadowplane, good luck fighting all the albino orcs & pitch black spiders. Lol.

The moment you go down, you will reach The dark wet tunnels. Wander around here east-ish and the scales will be on the floor. Use a guardian demon (holding a ball of light) to pick up the scales without getting out of shadow.
