OSRS Desert Treasure II Final Boss Guide for The Whisperer

This grandmaster quest, released in 2023, is renowned for its intense combat encounters and rewarding loot, including access to the Virtus robes and ancient rings. In this comprehensive guide, we’ll dive deep into strategies, mechanics, gear setups, and tips to conquer The Whisperer, helping you complete the quest and unlock its post-quest boss fights. Whether you’re a seasoned player or tackling this for the first time, this guide is packed with actionable advice to ensure victory.

The Whisperer is the final boss of Desert Treasure II, encountered after defeating the four Forgotten Four bosses: Duke Sucellus, Vardorvis, Leviathan, and Ketla the Unworthy. This fight is a test of endurance, requiring precise prayer switching, high DPS, and mastery of complex mechanics. The Whisperer is weak to magic, making it essential to bring your best magic gear and spells. The fight takes place in the Ancient Vault, with Sliske’s wights adding layers of difficulty through varied attack styles and special mechanics.

Why The Whisperer is Challenging

The Whisperer’s difficulty stems from its multi-phase mechanics and the need for constant prayer switching. Unlike earlier bosses, you can’t rely on safespotting, as all final bosses in DT2 run and use long-ranged attacks. The fight demands quick reactions to dodge special attacks, manage sanity-draining mechanics, and maintain high DPS to avoid being overwhelmed. For mid-level players, the DPS check in the final phase can be particularly tough, especially without best-in-slot (BIS) gear.

Key Quest Context

Before facing The Whisperer, you’ll need to complete the Desert Treasure II quest, which requires high skill levels, including 60 Runecraft, Firemaking, and Thieving. The quest’s narrative ties into the Mahjarrat series, with Sliske’s manipulations driving the final confrontation. After defeating the Forgotten Four, you’ll face a Mysterious Figure (revealed as The Whisperer) in the Ancient Vault, where the fight tests your ability to handle Sliske’s wights one by one.

Preparation for The Whisperer Fight

Proper preparation is crucial for success against The Whisperer. This section covers recommended gear, inventory setups, and stats to ensure you’re ready for the battle.

Recommended Stats

• Magic: 85+ (90+ preferred for higher DPS with spells like Shadow Barrage)
• Hitpoints: 80+ to survive chip damage and special attacks
• Prayer: 70+ for access to Augury and protection prayers
• Defence: 75+ for better tanking against Ketla’s ranged attacks

Gear Setup

Your gear should prioritize magic attack bonuses and ranged defence to counter Ketla’s clones. Here’s a recommended setup:

Slot	Best-in-Slot	Budget Alternative
Head	Ahrim’s hood	Infinity hat
Cape	Imbued God cape	Ardougne cloak
Body	Ahrim’s robetop	Mystic robe top
Legs	Ahrim’s robeskirt	Mystic robe bottom
Weapon	Kodai wand	Master wand
Shield	Arcane spirit shield	Mage’s book
Ammo	Blessed dragonhide	N/A

Note: Bring a blowpipe or darts for Ketla’s clones to quickly dispatch them and reduce chip damage.

Inventory Setup

• Food: 10-12 Saradomin brews or sharks for healing
• Potions: Super restore (4), magic potion (4), ranging potion (for blowpipe)
• Runes: Enough for 100+ casts of Shadow Barrage (Blood, Soul, and Death runes)
• Switch: Toxic blowpipe or rune darts for Ketla’s clones
• Utility: Stamina potion, anti-venom (for earlier fights)

Mechanics of The Whisperer Fight

The Whisperer fight is divided into phases, each featuring Sliske’s wights and unique mechanics. Understanding these is key to surviving the encounter.

Phase 1: Ketla the Unworthy

Ketla uses ranged attacks and spawns clones that deal chip damage. Use high ranged defence armor (e.g., Torag’s or Verac’s) and pray Protect from Missiles. Quickly dispatch clones with a blowpipe or darts, leaving two clones to block Ketla’s main attacks. Focus DPS on Ketla while dodging her projectiles.

Phase 2: Mysterious Figure and Orbs

The Mysterious Figure freezes you and launches dangerous orbs. Spam-click to move while frozen to dodge these orbs, which deal significant damage. Pray Protect from Magic and use Shadow Barrage to maximize DPS. If you die or leave, you can return via a portal south of the Bandit Camp Quarry.

Final Phase: The Whisperer’s Sanity Drain

In the final phase, The Whisperer drains your sanity, dealing rapid damage if you go insane. This is a DPS race—use Augury and your strongest magic spells to kill her before sanity depletes. Splashing (missing attacks) can be deadly, so ensure your magic accuracy is high. Dodge lightning attacks and focus on the boss, ignoring portals unless absolutely necessary.

Strategies and Tips for Success

Here are proven strategies and tips to defeat The Whisperer, drawn from community insights and expert guides.

General Combat Tips

• Prayer Switching: Alternate between Protect from Missiles (Ketla) and Protect from Magic (Whisperer). Practice quick switches to avoid taking unnecessary damage.
• DPS Focus: Prioritize DPS over mechanics in later phases, as killing the boss quickly reduces the impact of special attacks.
• Positioning: For Ketla, stand with a clone between you and her to block big attacks. For The Whisperer, run to a corner opposite the room’s entrance to avoid abyssal leech aggro.

Managing the Final Phase

The sanity-drain mechanic makes the final phase a race against time. Here’s how to handle it:

1. Boost your magic with a potion before entering the phase.
2. Use Shadow Barrage consistently, avoiding low-accuracy spells.
3. If sanity drops below 50%, eat to full health to survive potential rapid damage.
4. Ignore portals unless they block your movement, as they’re less critical than DPS.

Budget and Ironman Tips

For players without BIS gear or Ironmen, the fight is still manageable with adjustments:

• Weapons: Use a Trident of the Seas instead of a Kodai wand for reliable damage.
• Armor: Mystic robes and a dragon square shield offer decent defence on a budget.
• Clones: Mithril darts or a rune crossbow can replace a blowpipe for Ketla’s clones.
• Food: Stock up on tuna potatoes or karambwans for cost-effective healing.

Post-Quest Rewards and Awakened Variants

Defeating The Whisperer completes Desert Treasure II, unlocking the ability to fight the Forgotten Four as repeatable bosses, including their challenging Awakened variants. These bosses drop valuable loot like Virtus robes, the soulreaper axe, and ancient rings. The Awakened versions are targeted at high-level players and require Orbs, which can be traded on the Grand Exchange, creating a lucrative economy loop.

Loot and Rewards

The Whisperer and other DT2 bosses have GWD-style drop tables, with unique items like:

• Virtus Robes: Best-in-slot magic armor for high-level PvM.
• Ancient Rings: Powerful rings with unique effects for various combat styles.
• Soulreaper Axe: A high-damage melee weapon with special attack potential.

Why Replay the Bosses?

Post-quest, the Forgotten Four and their Awakened variants offer aspirational content for PvM enthusiasts. The regular bosses are challenging yet accessible, while Awakened versions cater to players comfortable with content like the Inferno or high-invocation Tombs of Amascut. Completing all four Awakened bosses guarantees a Blood Torva kit, a prestigious cosmetic upgrade.
