Core is one of the most iconic and rewarding raid bosses in L2M Diamonds. Known for her powerful mechanical attacks, dangerous minions, and valuable drops, Core is a must-farm target if you want to upgrade your gear and push deeper into endgame content. This guide covers everything you need to know — from preparations and mechanics to optimal strategies for defeating Core efficiently.

1. Where to Find Core

Core is located in the Cruma Tower, one of the most challenging mid-to-late-game PvE zones in Lineage 2M. The higher floors contain powerful golems and golem guardians, but the boss chamber stands out due to strong healing suppression, persistent AoE damage, and constant add spawns.

Core spawns at fixed intervals, and competition can be high on some servers, so arriving early is recommended.

2. Recommended Combat Power (CP)

To participate safely and efficiently:

Minimum CP: 1.6M–1.8M (for support roles or ranged DPS in organized groups)

Optimal CP: 2M+ (for frontline or semi-solo attempts)

Having a balanced party with proper buffs matters more than raw CP alone.

3. Best Classes for Fighting Core

While any well-built party can defeat Core, some classes have clear advantages:

Best DPS

Ranger / Hawkeye / Silver Ranger – consistent ranged damage and safe positioning

Dark Wizard / Elemental Wizard – strong AoE pressure for handling adds

Assassin / Abyss Walker – high burst damage for shredding boss HP quickly

Best Tanks

Knight / Temple Knight / Shillien Knight – strong mitigation and reliable taunt

Paladin – excels at stabilization during heavy burst phases

Best Support

Bishop – strongest AoE heals

Sword Muse / Warcryer – top-tier buffs that significantly boost party DPS

4. Core’s Main Mechanics

Core is defined by mechanical precision. Understanding the fight pattern is key.

1) Shock Pulse (AoE Burst)

Core periodically emits a high-damage electric burst.

Counter:

Ranged classes should stay at max distance.

Healers must prepare AoE heals.

2) Magnetic Pull

Core pulls all players toward her, setting up a follow-up Shock Pulse.

Counter:

Tanks must pop mitigation.

DPS should immediately move out after the pull.

3) Golem Minion Adds

Core summons mechanical golems that buff her or apply damage pressure.

Counter:

Assign 2–3 players to burst them ASAP.

Wizards excel here with AoEs.

4) Defense Mode

Core temporarily reduces damage taken and regenerates HP.

Counter:

Stop wasting big cooldowns.

Focus on add control until defense mode ends.

5. Step-by-Step Strategy to Beat Core

Here is the safest and most reliable approach:

Step 1: Tank Positioning

Tank pulls Core to a corner or wall to limit add spread.

Keep Core facing away from the group.

Step 2: Control the Adds

Kill golem spawns immediately.

Leaving adds alive prolongs the fight and increases damage taken.

Step 3: Avoid AoEs

Move out after magnetic pulls.

Ranged players maintain 12m–16m distance.

Step 4: Burst During Vulnerable Windows

Core has periods where her defenses drop — this is your DPS window.

Step 5: Maintain Buffs and Healing

Support classes should cycle buffs continuously.

Healers need to anticipate Shock Pulses, not react to them.

6. Core’s Loot Table – What You Can Earn

Defeating Core rewards valuable items used for mid-to-late-game gear progression, including:

Rare Armor Pieces

Enchantment Scrolls

Spellbooks

Core Rings and Accessory Components

High-value crafting materials

Adena and other consumables

Accessories from Core are especially sought-after due to their powerful combat stats.

7. Extra Tips for Faster & Safer Kills

Join an organized clan to secure kills during busy spawn times.

Use potions and elixirs before entering Cruma Tower.

Equip anti-mechanical damage gear if available.

Keep resurrection scrolls in case of wipe scenarios.

A well-prepared party can take Core down in 2–5 minutes depending on CP.

Final Thoughts

Core is one of the most rewarding bosses in cheap L2M Diamonds, offering steady rare loot, great XP, and a satisfying challenge. With the right preparation, structured roles, and awareness of her mechanics, any group can farm Core consistently.
