Umbral Monument: Turbidity Manifest Overview

Turbidity Manifest is the fourth series added to Umbral Monument, the permanent endgame challenge mode in Arknights: Endfield. This special game mode features six challenging stages that test operator positioning, crowd control, stagger and interrupt management, and overall team synergy.

The six stages in Turbidity Manifest are:

• Stage 1: Silent Horizon

• Stage 2: Withered Sea

• Stage 3: Tidal Grief

• Stage 4: Underflow Chasm

• Stage 5: Blood Debased

• Stage 6: Cryostatic Connection

Each stage in Umbral Monument Turbidity Manifest comes with two difficulty modes: Normal Mode, which is recommended for level 60 players and Agony Mode, which is recommended for level 90 players. However, many Arknights: Endfield beginners struggle to clear all stages due to stronger enemies, intense boss fights, and heavy survival mechanics.

Because of this, we decided to create the best Turbidity Manifest guide with all the important details and tips for clearing all the stages and winning the battle more easily.

Stage 1: Silent Horizon

This stage is a multi-wave survival battle where strong enemies keep spawning in the center. Your goal is to clear the grouped enemies before they overwhelm your team.a

Main Enemies & Mechanics

• Hazefyre Claw and Tuskbeast are tanky enemies that become stronger over time by gaining ATK stacks.

• Enemies appear in multiple waves from the center area.

• If left alive too long, enemies can quickly pressure your team.

• In Agony Mode, enemies have higher HP and deal more damage, while consumables cannot be used during the battle.

Best Strategies to Complete the Stage 

• Wait for full enemy waves - Save your Skills and Ultimates until most enemies gather together for better AoE damage.

• Fight near the center - Staying close to the middle helps you hit more enemies at once.

• Use crowd control - Freeze, slow, pull, or stun enemies to stop them from spreading.

• Bring healers or shields - The fight lasts a long time, so sustain units are very helpful.

• Use Gilberta effectively - Her grouping and displacement skills are excellent for controlling enemy waves.

• Reposition early - Move before enemies surround your team and create too much pressure.

Stage 2: Withered Sea

Stage 2 starts with dangerous elite enemies before the main boss appears. You must survive the early pressure and prepare properly for the boss fight.

Main Enemies & Mechanics 

• Strong elite enemies appear in the first phase and deal heavy damage.

• After clearing the elites, the main boss enters the fight.

• In Agony Mode, the stage becomes harder because enemies are stronger and consumables cannot be used.

Best Strategies to Complete the Stage

• Build resources early - Generate SP and save Ultimates while clearing the slug enemies.

• Prepare for the boss phase - Reposition your team before the boss fully engages.

Stage 3 is focused on controlling enemies before they reach the center and explode. Good positioning and target priority are very important here.

Main Enemies & Mechanics

Mudflow enemies, especially the blue δ variants, move toward the center and explode for massive damage.

• Blue variants are harder to interrupt or push away.

• Enemy waves become larger and more dangerous over time.

Best Strategies to Complete the Stage

Main Enemies & Mechanics 

• Effigy uses slow slam attacks, charge beams, grab attacks, and dark matter summons.

• The boss also summons Aggeloi Adds during the fight.

• Effigy has balanced resistances, so no damage type has a major advantage.

Best Strategies to Complete the Stage

• Attack from the side or behind - The boss turns slowly, so circling around it helps avoid dangerous frontal attacks.

• Interrupt attacks quickly - Stop charge beams and grab attacks as soon as possible using interrupt skills.

• Handle adds fast - Clear or crowd-control Aggeloi enemies while continuing to damage the boss.
