To retrieve a Salve shard, a powerful item imbued with Saradomin’s energy, guarded by the restless spirit of Treus Dayth.

Quest Requirements and Prerequisites

Before you can face the Haunted Mine battle, you’ll need to meet the following requirements:

Completed Priest in Peril: Unlocks access to Morytania.
Started Nature Spirit: Optional but helpful for swamp navigation with a Druid pouch.
Level 15 Agility: For navigating the mine’s obstacles.
Level 35 Crafting: To cut the Salve shard with a chisel.
Combat Readiness: Ability to defeat a level 95 enemy (Treus Dayth).

Why the Haunted Mine Battle Matters

The battle against Treus Dayth isn’t just a test of combat prowess—it’s a rite of passage for OSRS players seeking the Salve amulet. This iconic item provides a 15% boost to Attack and Strength against undead creatures, making it invaluable for Slayer tasks and bossing. The quest also offers 22,000 Strength XP, a hefty reward for mid-level players.

Preparing for the Haunted Mine Battle

Success in the Haunted Mine battle hinges on proper preparation. Treus Dayth is no pushover, and the mine itself poses environmental hazards that can quickly overwhelm the unprepared. Here’s how to gear up.

Recommended Gear and Inventory

Your setup will depend on your combat level, but here’s a solid baseline:

Weapons: A strong melee weapon (Rune scimitar or better) or magic (Crumble Undead spell with 39 Magic).
Armor: Rune armor or equivalent for melee; Mystic robes for mages.
Food: 10-15 high-healing items like sharks or monkfish.
Prayer Potions: 1-2 doses to sustain Protect from Missiles.
Chisel: Essential for cutting the Salve shard (can be picked up in the mine if forgotten).
Teleport: Ectophial or Mort’ton teleport scroll for a quick exit.
Druid Pouch: To fend off ghasts in Mort Myre Swamp en route.

Getting to the Abandoned Mine

Reaching the battle site is half the challenge. Start by heading to Mort Myre Swamp. The fastest routes include:

Mort’ton Teleport Scroll: Drops you near the mine entrance.
Shades of Mort’ton Minigame Teleport: Requires completion of that quest.
Manual Route: Travel south from Canifis through the swamp, using the “In Search of the Myreque” shortcut if unlocked.

Once at the mine, speak to the Zealot, pickpocket him for the key, and begin your descent.

Navigating the Haunted Mine

The Abandoned Mine is a labyrinth of carts, levers, and glowing fungi, all leading up to the climactic battle. This section covers the key steps to reach Treus Dayth.

The Mine Cart Puzzle

One of the trickiest parts of the quest is the mine cart puzzle, which you must solve to transport a glowing fungus (your light source) to the lower levels. Here’s a simplified breakdown:

Pick a glowing fungus from the pools on Level 4.
Place it in the searchable cart northwest of the pools.
Head to the points settings panel and adjust levers A-E (west) and F-K (east) to match the correct path.
Correct settings: Flip levers B, C, and D. The cart should reach the ladder in the top-right corner.

If the cart sinks, grab another fungus and try again. Once successful, retrieve the fungus from the cart’s destination.

Descending to the Boss Chamber

With the fungus in hand, navigate back through the mine:

Climb the ladder near the fungus spawn.
Go north past the haunted cart, east, and up another ladder.
Exit west, re-enter via the southern cave, and descend multiple ladders until you reach the water valve.
Use the Zealot’s key on the valve to flood the lower level, granting access to Treus Dayth.

The Haunted Mine Battle: Facing Treus Dayth

Treus Dayth, a level 95 ghost, is the highlight of the Haunted Mine quest. This fight combines combat with environmental awareness, making it a unique challenge in OSRS.

Treus Dayth’s Mechanics

Treus Dayth doesn’t attack directly—instead, he summons flying pickaxes (ranged damage) and manipulates the room’s machinery:

Pickaxes: Deal moderate ranged damage; mitigated by Protect from Missiles.
Cranes: Swing unpredictably, hitting for 25-35 damage if you’re caught in their path.
Teleportation: Treus moves around the room, forcing you to chase him.

Combat Strategies

Here are two effective approaches to defeat Treus Dayth:

Melee Strategy

Equip Protect from Missiles to reduce pickaxe damage.
Corner Treus in the northeast of the room by attacking and running near him.
Move west to the detached northern shaft, attacking from a distance to avoid cranes.
Use food to heal crane hits (unavoidable without perfect timing).

Magic Strategy

Use Crumble Undead (requires 39 Magic, Slayer staff recommended).
Stand in a safe spot (e.g., northwest corner) to minimize crane damage.
Cast repeatedly while managing prayer and health.

Tip: If you die or teleport out, you’ll need another glowing fungus, but the lever settings remain fixed.

Post-Battle Steps

Once Treus is defeated:

Take the “innocent-looking key” from the crate.
Exit east, go upstairs, then west to the crystal chamber.
Use the key to unlock the door and cut a Salve shard with your chisel.
