OSRS Pandemonium Quest Guide: How to Unlock Advanced Sailing Routes

With the Sailing skill becoming a major feature in modern OSRS gold, new quests tied to exploration, naval combat, and deep-sea navigation have become crucial for unlocking the best sailing content. One of the most important of these is the Pandemonium Quest — a mid- to high-level adventure that grants access to Advanced Sailing Routes, allowing faster travel, new resource zones, and higher-tier naval encounters.

If you're preparing to master Sailing or want access to the most profitable ocean routes, this guide will walk you through requirements, quest steps, boss tactics, rewards, and how to unlock every advanced route.

Skill Requirements

Sailing: 45+ (60+ recommended)

Crafting: 40

Smithing: 35

Magic: 33

Agility: 40

Combat Level: 70+ strongly recommended

Ship Requirements

Your ship must be at least:

Tier 2 Hull

Tier 2 Sails

You can finish the quest with weaker gear, but the naval encounters will be significantly harder.

2. How to Start the Quest

Start the quest by speaking to Captain Thalric at the Port Sarim Docks.

He explains that strange demonic activity has been detected near the southern Maelstrom Sea and that the Royal Navy needs help investigating. You will be tasked with escorting a scouting vessel, navigating storm barriers, and ultimately confronting the source of the pandemonium.

Accepting the quest will unlock the Pandemonic Sea Chart, a critical item for the route unlock later.

3. Quest Walkthrough – Step by Step

Step 1: Escort the Scout Ship

You will sail alongside a fragile scout ship toward the Drifting Expanse.

Avoid:

Reef hazards

Small pirate ambushes

Storm swirls

Your goal is simply to keep the scout alive.

Tip: Position your ship slightly ahead and draw aggro away from the scout vessel.

Step 2: Investigate the Burning Horizon

Once the scout ship is destroyed (scripted), you must investigate the Burning Horizon, a stretch of red-glowing sea. Sail close to the fiery water, trigger a cutscene, and prepare for your first naval battle.

First Mini-Boss: Infernal Skimmer

This small demonic ship attacks with:

Fire lash (damages sails)

Demon crew ranged attack

Magma wave (line-area damage)

How to Beat It

Keep your ship angled diagonally to avoid frontal attacks

Use cannon shots at max range

Repair sails immediately when damaged

Killing the Skimmer unlocks a new travel node and continues the quest.

Step 3: Board the Pandemonium Hulk

After defeating the Skimmer, navigate to the marked red sea zone. A cutscene triggers where you board the Pandemonium Hulk, a massive corrupted vessel.

Inside, you will:

Fight demon crew

Navigate burning corridors (Agility shortcuts help)

Solve a rune alignment puzzle

Rune Puzzle Solution

Align the runes in this sequence:

Fire

Air

Chaos

Blood

This opens the hull door to the boss room.

Step 4: Defeat the Flamebound Navigator (Boss Fight)

Boss Abilities

Flame Pulse: Magic AoE; pray Magic

Burning Tether: Roots you; move as soon as the animation ends

Infernal Tide: Summons fire waves; step into safe tiles

Summon Imps: Low damage but disrupt healing

Strategy

Always use Protect from Magic

Bring high-healing food and Saradomin brews

Clear imps only if they surround you

Move at the edge of the arena to dodge fire waves

Use melee or ranged — both work

Once defeated, loot the Demonic Compass from his body.

Step 5: Escape the Ship & Return to Port Sarim

The Pandemonium Hulk begins sinking, so you must:

Run back through the corridor

Jump across collapsing planks

Use rope to swing to your ship

Sail back to Captain Thalric

Completing this step finishes the quest.
