What Are Mythic Weapons

Mythic Weapons, officially designated as “The Myriad Arms of Bahrain,” represent twenty distinct legendary armaments in Final Fantasy XI, with each weapon corresponding to specific job roles except Geomancer and Rune Fencer. These powerful artifacts are exclusively obtained through the comprehensive “Arms of Balrahn” quest series. Each Mythic Weapon features a unique weapon skill that becomes accessible upon completion, providing game-changing combat capabilities that significantly enhance job performance in endgame content.

For adventurers seeking to understand the creation process, this guide provides comprehensive step-by-step instructions. While Cloudchief’s video offers visual guidance, our detailed written walkthrough ensures you won’t miss any critical steps in this complex undertaking.

How to Make a Mythic Weapon

Before initiating your Mythic Weapon journey, you must complete all Treasure Missions and achieve the prestigious Captain rank by successfully finishing all 50 Assault missions. This foundational requirement ensures you have the necessary game knowledge and progression to tackle the substantial challenges ahead.

Your first tangible step involves venturing to Nyzul Isle to secure the foundational weapon. These base items drop from any Notorious Monster encounter and are guaranteed rewards from bosses located on floors 20, 40, 60, 80, and 100. Strategic planning for these initial acquisitions can save dozens of hours compared to random farming approaches.

Once you possess the weapon foundation, maintain your Captain rank status while clearing all 100 floors of Nyzul Isle to obtain the essential runic disc. This critical component must then be traded alongside your weapon to Naja’s designated assistant to progress the questline.

The next phase requires eliminating specific high-priority targets across multiple zones. Importantly, if you’ve previously defeated these enemies for other content, those victories count toward your Mythic progression. Your specific objectives include defeating all four Chariot bosses within the original Salvage areas, eliminating the three designated Beastmen leaders in treasure zones, and successfully completing the challenging Odin chamber encounter.

BOSS YOU NEED TO KILL

Following these combat achievements, return to Naja for a critical story cutscene. After viewing this narrative progression, journey to Nashmau where a mouse NPC awaits your consultation. This character provides essential guidance for the subsequent resource collection stages of your Mythic Weapon creation.

The subsequent stage demands accumulating 100,000 Acre through systematic chamber clearing in Einherjar. For maximum efficiency, prioritize the final three chambers which yield the highest point rewards. Completing the three highest-tier chambers typically provides approximately 2,000 points per run, meaning you’ll need slightly over fifty completions if starting from zero accumulation.

Parallel to Acre collection, you must gather 150,000 points from Nyzul Isle completions. Point acquisition scales with both the quantity and elevation of floors cleared. Optimal strategy involves utilizing a mule character to reach floor 496, then maximizing ascent until time expiration. Well-executed runs of 26-27 minutes typically yield between 6,000 to 10,000 Nyzul points based on performance metrics.

The most substantial resource requirement involves collecting 30,000 Alexandria pieces. Arrapago Remnants II represents the most efficient farming location, averaging approximately 100 Alexandria daily, though this is limited to one attempt per day. Bhaflau Remnants serves as the secondary option without daily restrictions. Monthly Ambuscade participation provides 1,750 Alexandria, while player bazaars typically offer Ambuscade rewards between 6,000-9,000 gil depending on server economy, providing acceleration options for well-funded adventurers.

After delivering all accumulated resources to the mouse NPC, advance to the subsequent quest phase. Proceed to Whitegate and interact with the physical gate leading toward the palace to trigger another story cutscene. Subsequently, navigate near the Einherjar entrance where a significant tombstone marker awaits. At this location, trade the required tier 4 Zeni Notorious Monster trophies to the tombstone to continue progression.

TOMBSTONE

The culminating phase involves completing the “Forging a New Mythic” BCNM within Nyzul Isle. Crucially, ensure your unfinished Mythic Weapon is equipped before entering the battlefield instance.

Upon entry, you’ll confront an initial boss encounter. Reduce this opponent’s health to approximately 50% to trigger the spawn of a secondary boss entity. This second adversary will initially execute your Mythic Weapon’s signature weapon skill against you, thereby unlocking this ability if not previously accessible.

The combat mechanics require precise weapon skill execution at specific TP thresholds: utilize weapon skills between 1,000-2,000 TP to activate level 1 aftermath, between 2,000-3,000 TP for level 2 aftermath, and precisely at 3,000 TP for level 3 aftermath. The boss maintains regeneration capabilities and cannot be defeated until all three aftermath levels are successfully triggered. During this encounter, you’ll regenerate 10 TP per tick, facilitating the necessary weapon skill sequencing. After achieving all aftermath levels, proceed to eliminate the boss to complete the weapon forging process.

Return to the tombstone to access the BCNM entry point, then journey back to Whitegate and inspect the gate for the concluding narrative sequence. Finally, consult with Naja to receive congratulations on successfully completing your level 75 Mythic Weapon.
