Forerunner represents one of Destiny 2’s most sought-after Exotic sidearms currently available, though securing it demands considerable dedication and strategic planning.

The latest major Destiny 2 update serves as an extensive tribute to developer Bungie’s gaming legacy, prominently featuring their iconic Halo series work. Among the newly introduced arsenal are numerous weapons drawing inspiration from Halo designs, with most obtainable through the fresh six-player Dares of Eternity activity. However, Forerunner requires additional effort beyond standard event participation. This distinctive Exotic sidearm clearly replicates the legendary magnum pistol from Halo’s universe. Below you’ll discover comprehensive guidance for initiating the Magnum Opus questline and detailed completion requirements.

You’ll first acquire the Magnum Opus quest within the Treasure Hoard location, accessible after your initial Dares of Eternity completion. (Return visits are possible by choosing Eternity from your Director interface.) Your primary objective involves gathering seven Strange Coins before reporting back to Starhorse, who provides weekly challenge bounties connected to Dares activities in exchange for these coins.

Strange Coins function as the essential currency for progressing through the Magnum Opus questline. These valuable items drop randomly during Dares of Eternity completions, with higher difficulty levels typically yielding increased acquisition rates. For optimal farming efficiency, focus on consecutive Normal difficulty runs while maintaining consistent performance.

Pro Tip: Coordinate with fireteam members to maximize efficiency – designate specific roles for orb collection, enemy clearing, and power-up gathering during each run. This coordinated approach can reduce your coin collection time by approximately 30-40% compared to solo attempts.

Common Mistake: Many players underestimate the value of consecutive runs. The game’s reward system often provides better drop rates during extended play sessions, so plan for multiple consecutive completions rather than sporadic attempts.

The subsequent phase requires obtaining and finishing three distinct Starhorse bounties—crucially, you can only maintain one active bounty simultaneously, so carefully review each bounty’s requirements before selection. Difficulty varies significantly between available bounties, with more challenging objectives granting accelerated progression toward this quest milestone. You must accomplish all bounty criteria within a single Dares of Eternity session, maintaining concentration on specific task requirements. Repeating identical bounties isn’t permitted, so avoid excessive focus on particular weapon types like pulse rifle eliminations.

Regarding lower-complexity bounties demanding only 160,000 points per run, Normal difficulty generally suffices. Achieving the 180,000+ point thresholds necessary for advanced bounties remains feasible on Normal difficulty as well, though you should implement every available strategy to optimize scoring—systematically collect power-ups and light orbs, eliminate maximum enemy numbers, and exercise caution during the chaotic obstacle course segments to access optimal power-up quantities.

Advanced Strategy: For maximum efficiency, prioritize bounties that align with your current loadout and playstyle. If you’re already using a specific weapon type, select corresponding bounties to accomplish multiple objectives simultaneously. This approach mirrors the strategic weapon selection discussed in our BF6 Weapons Unlock guide, where loadout optimization significantly impacts performance.

Time Management: Each bounty typically requires 20-30 minutes for completion. Planning your session around three consecutive runs with complementary bounties can complete this step in approximately 60-90 minutes.

Your next objective involves securing a Strange Key. This item operates separately from standard treasure keys utilized for Treasure Hoard rewards, though acquisition remains relatively straightforward. As you finish Dares of Eternity attempts, you’ll accumulate Strange Favor reputation. These reputation gains advance your standing with Xur and unlock various rewards. Upon reaching Rank 4 reputation tier, you can collect a Strange Key directly from Xur. Simply interact with him at the Treasure Hoard location to view the progression track displaying unlockable rewards at specific rank milestones.

Rank Progression Insight: Each Dares completion on Normal provides approximately 150-200 Strange Favor, meaning you’ll need 8-12 completions to reach Rank 4. Consider mixing in Legend difficulty runs for accelerated reputation gains if your power level permits.

Efficiency Tip: Complete bounties during your reputation farming sessions to maximize progress across multiple objectives simultaneously.

After obtaining a Strange Key, converse with Xur once more to receive your subsequent quest objective. This directs you to utilize the key and follow a designated route to retrieve an “anomalous object.” You can track a waypoint marker leading into the Valley region, where Dares activities commence. (Should the waypoint not appear, utilize the portal mechanism positioned behind the spawn point at Treasure Hoard; simply remain within it for several seconds to transport.)

Stand on this side of the rock on the left side of the screen, and you'll be able to use the key

Position yourself on this specific side of the rock formation visible on your screen’s left portion to activate the key

Proceed directly into the expansive circular zone ahead, then orient yourself rightward. Navigate toward the perimeter cliffs until you identify the distinctive rock configuration displayed above. You’ll activate your key at this location to deactivate a barrier concealing a hidden cavern on the Valley’s opposite side (which you might discover initially, though the barrier prevents advancement until key application). A navigation marker will guide you there following key activation.

Navigation Tip: If you struggle to locate the precise rock formation, look for three distinctive vertical stone pillars clustered together—the activation point sits between them.

Common Error: Players often attempt to use the key at the cave entrance rather than the designated rock formation. Remember: activate at rocks first, then proceed to cave.

Following successful key implementation and barrier deactivation, navigate to the newly accessible hidden cave. Inside, you’ll discover the anomalous object that transforms into your hard-earned Exotic sidearm.

Completion Timeframe: Most dedicated players can complete the entire Magnum Opus quest within 3-4 hours of focused gameplay. This efficiency-focused approach mirrors the strategic planning emphasized in our Battlefield 6 Complete Guide, where proper planning dramatically reduces completion times.

Forerunner stands as more than mere nostalgia—it’s a competitively viable sidearm with unique gameplay applications. The weapon features exceptional range for its class, making it effective in both PvE and PvP scenarios when mastered.

Weapon Mechanics: Forerunner’s exotic perk, “The Rock,” converts remaining ammo into a high-damage grenade, providing tactical versatility during challenging encounters.

Advanced Applications: Pair Forerunner with close-range weapons to cover multiple engagement distances effectively. This loadout strategy complements the class specialization principles outlined in our BF6 Class Guide, where complementary gear selection maximizes combat effectiveness.

Combat Strategy: Utilize Forerunner’s precision damage to eliminate minor enemies efficiently while conserving primary ammunition for tougher adversaries.

Mastery Tip: Practice the weapon’s unique firing rhythm—it has a distinct cadence that, when mastered, significantly improves target acquisition and elimination speed.
