The Black Trench stands as one of the most challenging and intricate areas in No Rest for the Wicked, blending environmental puzzles, combat encounters, and exploration rewards. Tied closely to the ‘Of Rats and Raiders’ questline, this subterranean network of sewers, flooded chambers, and narrow ledges demands precise navigation, resource management, and combat prowess. Players must manipulate water levels using specialized levers, hunt for hidden keys, and dodge deadly environmental hazards to progress toward the formidable boss Darak.
This guide provides a step-by-step path through the Black Trench, highlighting optimal entry points, checkpoint activations, secret shortcuts, and loot opportunities. Whether you’re struggling with the darkness, toxic waters, or aggressive rat-like foes, these strategies will help you conquer the depths efficiently.
Optimal Entry Points into the Black Trench
Accessing the Black Trench correctly sets the tone for a smoother traversal. While multiple entrances exist, the recommended starting point is from the Shallows or via the Rattigan quest path for seamless progression.
- Primary Entrance via Shallows: Descend from the Shallows area into the initial Whisper checkpoint. This path avoids unnecessary backtracking and positions you near early objectives.
- Alternative from Orban Glades: Swim through a large, dimly visible pipe in the southeast corner. This leads directly into the main trench but requires swimming stamina management.
- Rattigan Quest Route: Progressing through ‘Of Rats and Raiders’ unlocks sewer doors, granting access near key levers and bridges.
Upon entry, prioritize saving at the first Whisper shrine. These ethereal save points not only preserve progress but also respawn you safely if overwhelmed by the trench’s denizens.
Navigating the Initial Descent and Drainage Challenges
The opening sections immerse players in dim, hazardous corridors filled with patrolling enemies and precarious drops. Follow the leftward path from the entry Whisper, descending stairs to a marked door requiring the Drainage Cellars Key.
Finding the Drainage Cellars Key: Explore side alcoves off the main stairwell. Defeat lurking rodents and search glowing chests tucked behind debris piles. This key unlocks a critical door leading to the first major puzzle room.
Once inside, a mandatory cutscene reveals the water mechanics at play. Prepare for platforming: jump to lower levels, avoiding spiked floors and enemy ambushes. Here, you’ll encounter the first water lever.

Mastering Water Level Manipulation
The Black Trench’s core mechanic revolves around three distinct water levers, each altering flood levels to create paths, bridges, or blockades. Timing and sequence are crucial to avoid drowning or getting stranded.
| Lever Location | Effect | Prerequisite |
|---|---|---|
| First Lever (Post-Drainage Door) | Raises water in initial chamber | Drainage Cellars Key |
| Second Lever (Bridge Area) | Extends bridge and lowers select waters | Access via James Bond-style wall cling |
| Sewer Lever Handle (Deep Trench) | Final drainage to boss path | Sewer Lever Handle Keys (x2) |
Step-by-Step Lever Activation:
- Post-cutscene, raise the first water level to swim across flooded sections and access a ladder shortcut.
- Climb to the bridge overlook. Perform a dodge-roll cling to the wall, sidling around corners during invincibility frames to evade mobs, then pull the lever for bridge extension.
- Deep in the sewers, collect two Sewer Lever Handle Keys from guarded chests. Insert them to fully drain paths to Darak.
Essential Shortcuts and Time-Saving Routes
The Black Trench rewards thorough explorers with kickable ladders and connectable areas, linking the northern and southern sections for endgame efficiency.
- Northern Glades Connection: From Glades, kick down a ladder to reach a water-raise point. Swim through the newly accessible pipe to merge trenches.
- Checkpoint Skips: Utilize floating platforms as brief respite during toxic runs. Hug edges with fast evade dashes to minimize damage.
- Speed Challenge Path: After the second Whisper, dash through a narrow, mob-filled corridor. Prioritize food buffs for sustain, as leeching health from foes is limited.
These shortcuts not only speed up repeat visits but are vital for fetching items like the Crucible Serum, required for map completion.
Combat Strategies Against Trench Foes
Enemies in the Black Trench include swarming rats, armored raiders, and toxic sludge monsters. Gear recommendations: light armor for mobility, fire-based weapons to exploit weaknesses, and stamina potions.
Tips for Survival:
- Light sources (torches) dispel unnatural darkness, revealing hidden threats.
- Group enemies at chokepoints before engaging; ladders provide high ground advantage.
- Boss Prep: Stock healing items. Darak’s patterns involve sweeping attacks and summons—dodge behind pillars and counter during recovery.
Key Item Locations and Loot Guide
Beyond quest items, the trench hides premium gear.
| Item | Location | Use |
|---|---|---|
| Water Channel Key | Post-second lever, in submerged chest | Unlocks sewer passages |
| Crucible Serum | Northern Black Trench edge | Map connection item |
| Unique Weapons | Boss antechamber | High-damage rat-slayer |
Confronting Darak: Boss Battle Breakdown
After draining the final waters and climbing the spiral staircase, face Darak in his lair. This rat-lord boss employs area-denial floods and claw combos.
- Phase 1: Evade ground pounds; attack legs during wind-ups.
- Phase 2: Summons adds—clear them quickly to avoid overwhelm.
- Finish: Use environment (pillars) for cover; levers nearby can flood his arena for stuns.
Victory grants access to Sacrament shortcuts and quest advancement.
