Doom of Mokhaiotl Delve Guide (OSRS)

The Doom of Mokhaiotl is a high-level demon encounter designed around endurance, mechanical consistency, and efficient wave management. When approached correctly, it offers strong GP per hour, valuable uniques, and scalable profits depending on how deep you can delve.

At-a-Glance

• Recommended Delve: 1–16 (Deep Delves from 8+)

• Kills per Hour: ~2.7 (Twisted Bow)

• Profit per Hour: ~21.8M GP (average)

• Primary Combat Style: Ranged

• Difficulty: High (mechanics-focused)

Requirements

Recommended Stats

• Ranged 90+

• Hitpoints 90+

• Defence 70+

• Magic 80+

• Prayer 77+ (Rigour)

Quest & Unlocks

• The Final Dawn (required)

• Dragon Slayer II (Ava’s assembler)

• A Kingdom Divided (Arceuus spellbook)

Gear Overview

Ranged is the dominant style for consistent clears and safer positioning.

• Twisted Bow or Scorching Bow

• Elite Void Knight equipment

• Zaryte crossbow (special attack)

• Dragon knives or Toxic blowpipe

• Crystal halberd or Scythe of vitur (situational)

Step-by-Step Fight Strategy

Waves 1–6

• Use Arceuus thralls for passive damage

• Maintain Death Charge uptime

• Focus on clean positioning to minimize chip damage

Waves 7–8

• Damage ramps up significantly

• Resource management becomes critical

• Use Zaryte crossbow special every wave if available

Delve Levels 9+

• Best unique drop rates are reached

• Longer time spent here increases GP/hour

• Risk rises sharply if mistakes stack

Deep Delves Explained (8+)

The encounter is technically endless, limited only by execution and supplies. While every deep delve requires clearing waves 1–8, the real value comes from staying alive in the highest delve levels as long as possible.

• Delve 9 offers peak unique rates

• Resetting too often lowers effective GP/hour

• Optimal runs balance safety and duration

Profit Breakdown

Average Hourly Results

• Total Profit: ~21.8M GP/hour

• Supply Cost: ~1.26M GP

• Outputs (after tax): ~23.1M GP

Deep Delve GP Potential

• 1:00 run – ~44M GP/hour (isolated)

• 1:30 run – ~29M GP/hour

• 2:00 run – ~22M GP/hour

• 2:30 run – ~14.7M GP/hour

Actual results depend on consistency, resets, and survival during deep delves.

Common Mistakes to Avoid

• Ignoring Death Charge uptime

• Overusing brews early instead of managing damage

• Resetting deep delves too aggressively

• Poor positioning during volatile earth mechanics

Efficiency Note

Many players focus on consistent Delve 1–16 clears rather than risky deep pushes. If time or focus is limited, keeping runs stable often results in higher long-term profit.

FAQ

Is the Doom of Mokhaiotl good money?

Yes. Even without deep delves, consistent runs provide strong GP/hour with valuable uniques.

What delve level should I aim for?

Delve 9 offers the best unique rates, but only if you can survive efficiently.

Is a Twisted Bow required?

No, but it significantly improves completion speed and consistency.

How risky are deep delves?

Risk increases sharply with duration. Mistakes compound quickly at higher levels.

Can this be done on a budget setup?

Lower-tier setups are possible but will reduce completions per hour.
