Mirkwood Corrupted

Mirkwood Corrupted, the majority of Mirkwood which is corrupted - the trees are tall and dense, the grass is dark and Mirkwood Spiders are plentiful. Cobwebs can be found in the trees and on the ground, making navigation tricky. Slightly spooky black butterflies spawn here. Extremely rarely, Ruined Wood-elven Towers can be found here.

Upon Entering Mirkwood Corrupted you gain the achievement "Stay on the path"
