Lineage 2M continues to reward cooperative gameplay, and Lineage 2M Diamonds the Party Dungeon Double Time Event is one of the best opportunities for players to accelerate progression through teamwork. For a limited period, party dungeon rewards receive a major boost, allowing adventurers to earn twice the number of valuable boss chests simply by completing content they may already run daily.

If you want to grow stronger efficiently, this event is the perfect time to organize parties, optimize dungeon routes, and secure high-value rewards with minimal extra effort.

Event Schedule and Overview

The Party Dungeon Double Time event runs:

After maintenance on March 10, 2026 (Tue) → Until maintenance on March 25, 2026 (Wed)

During this period, players receive double quantities of Boss Secret Chests (Bound) upon clearing designated party dungeons.

This is not a drop-rate increase - it is a guaranteed reward multiplier. Every successful clear becomes significantly more valuable.

What Rewards Are Doubled?

During the event, completing specific party dungeons grants two Boss Secret Chests instead of the usual one. Each dungeon rewards its own unique chest tied to different bosses and progression materials.

The doubled rewards apply to the following dungeons:

Kite Pirates Base

Rewards Meruk's Secret Chest I–IV (Bound) ×2 per clear.

Secret Nebulite Depository

Rewards Lameer's Secret Chest (Bound) ×2 per clear.

Temple of the Seal

Rewards Macmeth's Secret Chest I–IV (Bound) ×2 per clear.

The Last Garden

Rewards Hatura's Secret Chest I–IV (Bound) ×2 per clear.

Ketra Barracks

Rewards Ketra's Secret Chest I–IV (Bound) ×2 per clear.

Gray Altar

Rewards Cruma's Secret Chest I–IV (Bound) ×2 per clear.

Because these chests commonly contain enhancement materials, crafting resources, and valuable progression items, receiving double rewards significantly accelerates character development throughout the event period.

Why This Event Matters for Progression

Party dungeons already represent one of the most efficient daily activities in Lineage 2M. With rewards doubled, their value increases dramatically.

1. Faster Gear Enhancement

Secret Chests frequently provide materials used for:

Equipment upgrades

Crafting progression items

Enhancement attempts

Running daily clears during the event can produce several weeks' worth of materials in just a few days.

2. Improved Resource Efficiency

Since dungeon entry limits remain the same, players gain more rewards without spending additional Adena or time.

This makes the event ideal for:

Free-to-play players

Returning adventurers catching up

Guild members preparing for PvP content

Efficiency is the real reward here.

3. Strong Incentive for Party Play

Lineage 2M's combat design shines in coordinated group content. The event encourages players to:

Rebuild active party groups

Coordinate class roles

Optimize dungeon clears

Stronger teamwork often leads to faster runs, allowing players to complete all daily entries quickly.

Best Strategy to Maximize Rewards

To fully benefit from Double Time, planning matters more than raw combat power.

Run Dungeons Daily After Reset

Party dungeon availability resets every day at:

12:10 AM

Make dungeon clears part of your daily routine during the event window. Missing even a few days means losing double rewards you cannot recover later.

Build Balanced Parties

An efficient party typically includes:

A durable frontline (tank or high-defense class)

Sustained damage dealers

Support or buffer roles

Balanced groups clear faster and reduce wipe risks, ensuring consistent chest rewards.

Prioritize Faster Dungeons First

If time is limited, begin with dungeons your group clears most efficiently. Consistency is better than struggling through higher-tier content that risks failure.

Speed farming becomes extremely valuable when rewards are doubled.

Coordinate With Guild Members

Guild coordination helps avoid long matchmaking waits and ensures reliable party composition.

Many guilds schedule dungeon rotations during events - joining organized runs can dramatically improve efficiency.

Important Event Precautions

Keep these rules in mind:

Double rewards apply only during the event period.

Rewards return to normal after March 25 maintenance.

Dungeon entry resets daily at 12:10 AM.

Event details or rewards may change depending on updates.

Planning ahead ensures you don't miss the bonus window.
