Lineage 2M is known for its large-scale seasonal events, and Lineage 2M Diamonds the Alchemist Event brings one of the most exciting progression systems yet. Running from September 24, 2025, until October 15, 2025, the event introduces the Mastering Alchemy Season Pass and a new crafting mechanic using the Alchemist’s Stone (Event). Whether you are a free-to-play adventurer or a veteran who wants to maximize rewards, this guide will cover everything you need to know about the event schedule, rewards, Season Pass, and how to make the most of Event Alchemy.

Event Schedule

Start: After maintenance on September 24, 2025 (Wednesday)

End: Until maintenance on October 15, 2025 (Wednesday)

This gives players three weeks to complete Season Pass missions, gather Alchemist’s Stones, and maximize their crafting chances.

Mastering Alchemy Season Pass

At the core of the event is the Mastering Alchemy Season Pass, which offers two tiers of rewards: Common (Free) and Premium.

How it Works

You progress through Season Pass levels by completing Daily Missions and Seasonal Missions.

Each level provides rewards, with stronger bonuses in the Premium tier.

Even if you don’t activate Premium, you can still collect Common rewards.

Activation Details

Common Rewards: Free for all players, one activation per account.

Premium Rewards: Costs 10 million Adena to unlock, one activation per account.

Includes Einhasad’s Blessings x3,000.

Unlocking Premium also sends a Premium Activation Reward to all members of your clan via Clan Mail.

If you’re not in a clan, you will miss this bonus, so joining one is highly recommended.

Level Rewards and Progression

Each level milestone offers a reward, with the final reward obtainable after reaching Pass Lv.19.

Once Lv.19 is cleared, you can keep farming EXP to claim the final reward twice.

Daily missions reset every day at 5:00 AM, giving you a fresh opportunity to grind EXP.

Seasonal missions can only be completed once, so plan ahead.

Alchemist’s Stone (Event)

The Alchemist’s Stone (Event) is the special item at the heart of this event.

Obtained as a reward from completing Mastering Alchemy missions.

Used as an ingredient for Event Alchemy.

The more Stones you use, the higher the chance of obtaining rare, high-rank rewards.

This makes farming Season Pass levels absolutely critical, since your Stone supply directly impacts your crafting opportunities.

Premium Activation Reward

One of the unique aspects of this event is the clan-wide Premium Activation Reward. When a player in a clan activates Premium, the activation benefit is automatically sent out to all clan members via Clan Mail.

This reward can only be claimed by clan members.

If your character is not in a clan, you won’t be able to receive it.

For solo players, it may be worth temporarily joining a clan just for the rewards.

Event Alchemy

The second half of the event introduces Event Alchemy, where you use your collected Alchemist’s Stones as crafting ingredients.

How it Works

Go to Menu > Alchemy > Common Tab.

Select the Event Alchemy option.

Choose how many Alchemist’s Stones to use as ingredients.

Craft for a chance to obtain rewards.

Reward System

Rewards are divided into nine groups.

The group of rewards you can receive depends on the number of Alchemist’s Stones you used.

Each group has fixed chances, meaning you aren’t guaranteed top rewards, but your chances increase with higher investment.

This system encourages players to save their Stones and attempt high-tier alchemy for the best possible returns, instead of spending them one by one.

Tips to Maximize the Alchemist Event

1. Prioritize Season Pass Progression

Since the Stones come directly from Season Pass rewards, your first goal should be to grind daily and seasonal missions consistently. Missing even a few days could cost you precious Stones.

2. Consider Premium Activation

If you can spare 10 million Adena, unlocking Premium rewards is worth it:

You immediately gain 3,000 Einhasad’s Blessings, a significant boost.

Your clan benefits as well, making it a great option for active groups.

Premium guarantees you double-dipping into the reward structure, maximizing long-term value.

3. Save Stones for Higher-Tier Alchemy

Although it’s tempting to spend Stones as soon as you get them, it’s more efficient to stockpile and attempt higher-tier crafts. The nine reward groups scale upward, so using more Stones at once will dramatically improve your odds.

4. Join a Clan Before Activating Premium

Even if you prefer solo play, joining a clan during this event has major benefits. Not only will you receive clan-shared rewards, but your Premium activation also benefits your allies.

5. Push for Lv.19 and Beyond

The final Season Pass reward is available twice after Lv.19, so don’t stop grinding once you hit the milestone. Keep farming daily missions until the event ends to secure both final rewards.

Why the Event Matters

The Alchemist Event is more than just a seasonal activity—it’s a chance to supercharge your account progression. By participating, you gain:

High-value crafting materials via Alchemist’s Stones.

Adena and Blessings, critical for character growth.

Clan-based benefits that strengthen group play.

More importantly, the event introduces strategic decision-making: whether to save Adena for Premium, how many Stones to spend at once, and how to balance daily grind with seasonal goals.

Final Thoughts

The Lineage 2M Alchemist Event offers a rewarding three-week experience that blends daily engagement, clan cooperation, and high-stakes crafting. Running from September 24 to October 15, 2025, it revolves around collecting Alchemist’s Stones from the Season Pass and using them in Event Alchemy for rare items.

For the best results:

Complete your daily and seasonal missions consistently.

Activate Premium if you can afford the Adena cost.

Join a clan to maximize rewards.

Save Stones for high-tier alchemy attempts.

Whether you’re a casual player farming Common rewards or a dedicated adventurer investing in Premium, this event ensures plenty of progression and cheap Lineage 2M Diamonds excitement.
