If you're looking to complete The Heart of Darkness efficiently, this guide will take you through all the steps—requirements, walkthrough, boss fights, and rewards.

Before attempting The Heart of Darkness, you need to meet the following quest, skill, and item requirements:

Completion of the following quests:

The Lord of Vampyrium

The Branches of Darkmeyer

Legacy of Seergaze

The Darkness of Hallowvale

In Aid of the Myreque

In Search of the Myreque

Skill Requirements:

60 Magic

60 Prayer

(Combat level 100+ is strongly recommended.)

Items You’ll Need:

Combat gear suitable for both melee and magic enemies

Teleportation runes or jewelry (Varrock, Drakan's medallion, Ectophial)

Food and potions (prayer, restore, anti-poison)

Ivandis flail or Blisterwood weapon (for vampire enemies)

Quest Start: How to Begin

To start The Heart of Darkness, head to Burgh de Rott and speak to Veliaf Hurtz in the Myreque hideout. He will brief you on an ominous power emerging from the eastern marshes of Morytania, deep beyond the swamps. After accepting the quest, the game will auto-mark your mini-map with the first objective.

Walkthrough: Step-by-Step Completion

Step 1: Investigate the Source of Darkness

You’ll be sent into the eastern swamplands using a rowboat. Navigate through an instanced area filled with mutated swamp creatures and hidden traps.

Tips:

Use Surge or Bladed Dive to dodge marsh traps.

Light your path with a lantern or Seers' headband to reveal obstacles.

At the end, you’ll encounter a ruined altar. Interact with it to trigger a vision involving a new enemy faction—the "Children of Mah."

Step 2: Seek Out the Mahjarrat Connection

Return to Veliaf and then head to Rellekka to consult with Kharshai, a Mahjarrat who offers insight into this mysterious cult. He will instruct you to gather ancient relics tied to Zarosian rituals hidden in various tombs.

Relic Locations:

Senntisten Cathedral (Prayer unlock)

Kharid-et Dig Site (Archaeology level 60+ recommended)

Uzer Ruins (requires Ring of visibility or Ghostspeak amulet)

Once you’ve gathered all three relics, return to Kharshai.

Step 3: Decoding the Ritual

With the relics in hand, Kharshai will decode the ritual needed to cleanse the darkness. However, this attracts the attention of a powerful cult member named Serenite, who attempts to steal the relics.

Combat Encounter:

Level 200+ enemy

Uses both magic and shadow melee attacks

Protect from Magic is most effective

Bring stat restoration potions, as Serenite drains Prayer and Strength

Defeating her triggers a cutscene revealing that the Heart of Darkness is awakening in the ruins beneath Darkmeyer.

Step 4: Entering the Heart

Now armed with ritual knowledge, teleport to Darkmeyer using Drakan’s medallion. Use the sewer grate behind Vanstrom’s former lab to enter the hidden sanctum.

This area is puzzle-heavy and guarded by Shadows of Mah—monsters immune to basic attacks unless weakened by ritual fire.

Puzzle Tips:

Use the relics on brazier pedestals in correct order: Blood → Shadow → Ice

Light all three braziers within 60 seconds to unlock the gate

Avoid cursed tiles, which reset progress

Inside, you’ll confront the final boss: Malak d’Thul, a corrupted Myreque general.

Step 5: The Final Boss Fight – Malak d’Thul

Malak d’Thul is a multi-phase boss requiring quick reflexes and phase-awareness.

Phase 1 – Shadow Blasts

Avoid AoE explosions on the ground

Drain his shield with melee or Blisterwood

Phase 2 – Mirror Realm

You're pulled into a shadow version of the arena

Kill the shadow copies before returning

Phase 3 – Light Ritual

Light ritual braziers while dodging Malak’s projectiles

He becomes vulnerable after all four braziers are active

Combat Tips:

Bring plenty of food and 3–4 Prayer renewals

Use Freedom and Anticipation to break stuns

Dual wield or switch weapons for quick phase shifts

Once defeated, you’ll trigger a final cinematic revealing that the Heart of Darkness was part of a forgotten Mahjarrat experiment that could destabilize the realms of light and shadow.

Rewards and Unlocks

Upon completion of The Heart of Darkness, you’ll receive:

3 Quest Points

80,000 Attack XP

60,000 Slayer XP

60,000 Magic XP

Access to the Shadow Crucible Dungeon (daily elite mob farming area)

New Prayer unlock: "Sear the Shadow" (temporary immunity to shadow damage)

Malak’s Sigil – an off-hand item granting +5% damage to Vampyres

Final Tips

Be well-prepared before boss fights; quick banking between phases is not allowed.

Bring multiple teleport options—some areas have anti-teleblock fields.

Consider enabling Quest Helper or RuneLite plugins if you’re playing via RuneLite for better direction on puzzle solutions.
