In the vast world of Old School RuneScape (OSRS), few weapons command as much respect and intrigue as the Inquisitor’s Mace. Known for its devastating crush attacks and unique lore, this one-handed melee weapon is a favorite among high-level players tackling bosses, PvP, and Slayer tasks. In this blog post, we’ll dive deep into everything you need to know about the Inquisitor’s Mace, from its stats and requirements to its best uses and market trends. Whether you’re a seasoned player or just dreaming of wielding this powerful mace, this guide is for you.

The Inquisitor’s Mace is a one-handed crush weapon that requires 80 Attack to wield. It’s a rare drop from The Nightmare and its harder variant, Phosani’s Nightmare, making it a prestigious and valuable item in OSRS. With bonuses comparable to the Ghrazi Rapier and Blade of Saeldor, the mace stands out as the premier crush-style weapon, complemented by a unique +2 Prayer bonus. Its historical significance, tied to Phosani, a former Saradominist Justiciar, adds a layer of lore that enhances its appeal.

Key Stats and Features

Here’s a quick breakdown of the Inquisitor’s Mace stats:

Attribute	Value
Attack Bonus (Crush)	+95
Strength Bonus	+89
Prayer Bonus	+2
Attack Speed	4 (2.4 seconds)
Requirements	80 Attack

The mace excels in crush-based combat, making it ideal for enemies with low crush defense. Its prayer bonus is a rare feature for melee weapons, helping players conserve prayer points during extended fights.

Lore and Background

Once wielded by Phosani, a turncloak Justiciar who defected to Zamorak, the Inquisitor’s Mace was sealed in the Sisterhood Sanctuary beneath Slepe until The Nightmare’s arrival unearthed it. This dark history ties the mace to the Zamorakian faction, making it a Zamorakian item in the God Wars Dungeon, where it provides protection against Zamorak’s followers.

How to Obtain the Inquisitors Mace

Acquiring the Inquisitor’s Mace is no small feat. It’s exclusively obtained as a drop from The Nightmare or Phosani’s Nightmare, both challenging bosses requiring teamwork and preparation.

Defeating The Nightmare

The Nightmare, located in Morytania, is a group boss with complex mechanics, including totems, sleepwalking phases, and powerful attacks. To maximize your chances of obtaining the mace:

Form a Team: A group of 5–20 players is ideal, with roles like DPS, totem healers, and runners.
Gear Up: Use high-tier melee gear, such as Bandos or Torva, and bring prayer potions.
Learn Mechanics: Understand phases like Husks, Sleepwalkers, and the Totem charging to avoid wipes.

The drop rate for the Inquisitor’s Mace is rare, estimated at around 1/400 per kill, depending on team size and contribution.

Phosani’s Nightmare

Phosani’s Nightmare is a solo or small-team version of the boss, with increased difficulty but better drop rates. It requires precise prayer switching and movement to survive. Key tips include:

High Combat Stats: 90+ Attack, Strength, and Defence recommended.
Prayer Management: Bring plenty of prayer potions and use piety for DPS.
Practice: Expect a steep learning curve; practice in regular Nightmare first.

Phosani’s offers a slightly higher chance for the mace, making it a popular choice for skilled players.

Best Uses for the Inquisitors Mace

The Inquisitor’s Mace shines in scenarios where crush damage is optimal. Its versatility makes it valuable for various activities.

Bossing

The mace is best-in-slot (BiS) for several bosses with crush weaknesses, including:

Tekton (Chambers of Xeric): The mace’s high crush accuracy outperforms other weapons.
Vasa Nistirio (Chambers of Xeric): Ideal for attacking crystals during the fight.
The Nightmare/Phosani’s Nightmare: Its crush style maximizes DPS against the boss.
Sarachnis: A mid-tier boss where the mace excels for mid-level players.

Slayer Tasks

For Slayer, the mace is effective against monsters weak to crush, such as:

Basilisk Knights: Pair with a shield for optimal damage and defense.
Gargoyles: Combine with a Slayer helmet for bonus accuracy.
Abyssal Demons: Outperforms the Ghrazi Rapier in crush-focused setups.

PvP Combat

In PvP, the Inquisitor’s Mace is a niche but powerful choice. Its high crush damage can catch opponents off guard, especially when paired with the Inquisitor’s Armour set for a 7.5% damage and accuracy boost. However, its lack of a special attack limits its combo potential compared to weapons like the Dragon Claws.

Synergy with Inquisitors Armour

The Inquisitor’s Mace truly shines when paired with the Inquisitor’s Armour set, which requires 70 Strength and 30 Defence. The set boosts crush accuracy and damage, making it a game-changer for crush-based combat.

Armour Bonuses

Each piece of Inquisitor’s Armour provides a 0.5% damage and accuracy boost for crush attacks, with an additional 1.0% bonus when wearing the full set, totaling 2.5%. When wielding the Inquisitor’s Mace, each piece grants a 2.5% boost, up to 7.5% for the full set. This makes the combination ideal for:

High-DPS Scenarios: Maximize damage against crush-weak bosses.
Prayer Efficiency: The set’s higher prayer bonus complements the mace’s +2.

Trade-Offs

While powerful, the armour has weaker defensive stats (comparable to adamant) and penalizes stab and slash accuracy. This makes it a “glass cannon” setup, best for encounters with minimal incoming damage.

Market Trends and Value

The Inquisitor’s Mace is one of the most expensive weapons in OSRS, with prices fluctuating based on supply and demand. As of May 2025, its Grand Exchange price hovers around 800–900M GP, driven by its rarity and BiS status.

Price History

The mace’s price has seen significant spikes, reaching 820M GP in mid-2020 due to high demand for Nightmare runs. Recent updates, like the 2024 buff to the Inquisitor’s Armour set effect, boosted its value further by making the mace-armour combo more viable.

Is It Worth Buying?

Deciding whether to invest in the Inquisitor’s Mace depends on your goals:

Pros: BiS for crush-based content, prayer bonus, and long-term value due to rarity.
Cons: High cost, niche use cases, and competition from cheaper alternatives like the Elder Maul.

For players focused on endgame PvM or specific Slayer tasks, the mace is a worthwhile investment. However, budget-conscious players might opt for the Abyssal Bludgeon for similar crush damage at a fraction of the cost.

Flipping and Trading

The mace is a popular item for Grand Exchange flipping due to its high margins. Tools like GE Tracker can help track price trends, with recent data showing a 149.1M GP increase over the past month. Always check live prices before trading, as the mace’s low supply can lead to volatility.

In conclusion, the Inquisitor’s Mace is a powerhouse in OSRS, offering unmatched crush damage and unique synergy with its armour set. Whether you’re battling The Nightmare, crushing Slayer tasks, or flipping for profit, this weapon is a symbol of prestige and power. With its rich lore and high demand, it’s no wonder the Inquisitor’s Mace remains a coveted item in 2025.
