If you are below level 55, it is recommended that you get sneak.

Go to Beadeaux and take the left path at the first fork and take the tunnel down at (H-7). If you don't have Cursna, take a right on the first fork and examine The Mute to get silenced. Then head to (M-8) past The Afflictor, which would curse you if you weren't silenced (bring an Echo Drops if you need it). Now head to (H-9) and cross the bridge to the area with giant smokestacks. To the left of the bridge should be a ???. Examine it to get the key item "Corrupted Dirt". Return it for your reward.
