Blade and Soul introduces the Bountiful Harvest Treasure Trove, available from September 12 through October 3. This limited-time event offers players access to premium items including Gilded Triangular Gems, Aransu & Raven Prisms, and the highly sought-after Grand Phoenix Costume Set. Understanding the event timeframe is crucial for maximizing your rewards.

Eligibility and Access Requirements
To participate in the Treasure Trove event, your character must reach level 36 or higher. Each eligible character receives one free Treasure Trove Key daily throughout the event duration. This provides consistent access without additional investment, making it essential to log in regularly even if you don’t plan extensive purchases.
The event structure allows players to acquire premium items using in-game currency, though strategic planning is required to optimize your spending. Many players find that preparing their Blade and Soul gold reserves in advance helps them capitalize on high-value opportunities when they appear.
Core Gameplay Mechanics
Each Treasure Trove opening presents a selection of items available for purchase using your accumulated Blade and Soul gold. A critical limitation to understand: you can only purchase one item per Treasure Trove Key used, making selection strategy paramount.


Slot Expansion Strategy
Players can significantly enhance their reward potential by purchasing Treasure Trove Expansions from the Hongmoon Store. These expansions unlock six additional Treasure Trove slots for the entire event duration. The expanded interface dramatically increases your chances of encountering high-value items, making this one of the most impactful investments for serious participants.

Bulk Opening Efficiency
For players with multiple keys, the five-at-once opening option provides significant time savings while maintaining identical reward mechanics. This bulk approach consumes five keys simultaneously and provides proportional progress toward all milestone systems.

Star Rating System Analysis
Each Treasure Trove features a star rating system displayed at the top of the interface. While most Troves rate at one star, the system can generate two or three-star variants with progressively superior rewards.
The visual indicator provides immediate assessment of potential value, allowing experienced players to quickly identify priority acquisitions among their available options.
Crit Meter Management
Crit Meter represents a guaranteed reward mechanism that ensures at least a 2-star Trove after sufficient investment. Importantly, free daily keys don’t contribute to meter progression—only purchased keys advance this system.
Each purchased key adds 1-3 points (or 5-15 points with bulk openings) toward the 40-point maximum. Strategic players often track their meter progression to time major purchases for maximum efficiency.
Bonus Rewards System
The Bonus Rewards structure provides additional compensation based on your total Trove openings. This progressive system establishes milestones that reward players with extra Hongmoon Experience, additional gems, exclusive cosmetics, and other premium items regardless of individual Trove results.
Access the complete reward list and specific milestone requirements by clicking the Treasure Trove Info button within the interface. This transparency allows for precise goal-setting and resource allocation throughout the event duration.

Common strategic errors include neglecting to check milestone progress before making key purchases or failing to coordinate Crit Meter usage with high-value reward periods. Advanced optimization involves synchronizing these systems for maximum cumulative benefit.
Comprehensive Reward Catalog
The Bountiful Harvest Treasure Trove delivers an extensive selection of valuable items catering to diverse player needs. Beyond the highlighted Gilded Triangular Gems and Aransu & Raven Prisms, participants can acquire substantial quantities of upgrade materials, consumable items, and exclusive cosmetic content.
The event marks the triumphant return of the Grand Phoenix Costume Set, offering collectors a second chance at this prestigious appearance item.

Cosmetics Collection
| Grand Phoenix Costume Set | Iridescence Costume & Frostfeather Wings | Metamorphosis Costume & Hair |
|---|---|---|
| Kitsune Costume | Sky High Costume & Sky High Hat | Kitsune Head Adornment |
| Panda Headband | Eagle Eye Face Adornment | |
| Peace Maker Illusion Weapon Chest | Samurai Illusion Weapon Chest | Grand Phoenix Illusion Weapon Chest |
| Flame Dancer Pet | Grand Phoenix Pet | Sky Drake Pet |
Value assessment should prioritize items that directly enhance character progression, particularly for players working through weapon upgrade systems and progression milestones. The cosmetic collections offer substantial aesthetic value but vary in functional benefits.
Cost-Effective Purchase Strategies
Treasure Trove Key and Expansion bundles return with enhanced discount structures. The fundamental principle: buying larger quantities yields greater per-unit savings, making bundle purchases the optimal approach for players planning extensive participation.
Premium Membership Advantages
Premium Members receive additional daily benefits including one free Treasure Trove Key for 0 Hongmoon Coin through daily Hongmoon Store visits. This represents significant cumulative value over the event’s three-week duration.

All event items remain available until the October 3 maintenance, providing a clear deadline for acquisition decisions. Strategic planning should account for both the daily free access and bundled purchase opportunities to maximize return on investment.
For players new to progression systems or those optimizing their character builds, understanding the relative value of different reward categories helps prioritize spending effectively throughout the event lifecycle.
