# Invasions in MU Online: Types, Schedules and How to Take Advantage

Invasions are among the most anticipated events in MU Online Season 6. They break the monotony of regular farming, offer exclusive drops and bring the server community together around a shared objective. Understanding each invasion type — its mechanics, drops and optimal strategies — is essential for any player aiming to progress efficiently.

Invasion Types in S6

MU Online Season 6 features four main invasion categories, each with distinct characteristics and rewards.

Red Dragon Invasion

The Red Dragon appears on intermediate-level maps such as Devias and Noria. It is the most accessible invasion, recommended for players starting around level 150.

Core stats:

  • HP: approximately 800,000 to 1,200,000 (varies by server configuration)
  • Defense: 180–220
  • Attack: 450–600
  • Elemental Resistance: medium
  • Drops: Jewels of Bless, Soul and level 6–8 items with varied options

> [!TIP] > The Red Dragon has no HP regeneration. Once sustained DPS begins, it falls quickly. Long-range classes like Elf and DW have an advantage by avoiding its melee area-of-effect attack.

Golden Invasion

The Golden Invasion differs from other invasions: instead of a single powerful boss, it scatters golden monsters across multiple maps simultaneously. Golden Budge Dragon, Golden Lizard King and Golden Tantallos are the most common.

Map → Golden Monster → Main Drop
Lorencia → Golden Budge Dragon → Jewel of Bless x1-3
Devias → Golden Lizard King → Jewel of Soul x1-3
Noria → Golden Tantallos → Jewel of Life x1-2
Atlans → Golden Deep Cow → Jewel of Chaos x1-2
Tarkan → Golden Wheel → Box of Luck

Each golden monster has significantly lower HP compared to conventional bosses, but there are many of them and they respawn during the event. An efficient strategy is to rotate through maps in sequence, collecting kills and Jewels at high speed.

Blood Castle and Devil Square (Instanced Invasions)

Although technically events requiring a ticket or key item, Blood Castle and Devil Square function as controlled invasions. In S6:

Kundun Invasion

Kundun is MU Online's most iconic boss and the highest-prestige invasion in S6. It has 5 difficulty levels (Kundun 1 through 5), each with progressively higher stats.

LevelEstimated HPDefenseMagic AttackRecommended For
Kundun 12,000,000300600–800Level 200–250
Kundun 24,000,000380900–1,100Level 250–300
Kundun 37,000,0004601,200–1,500Level 300–350
Kundun 412,000,0005401,600–2,000Level 350–380
Kundun 520,000,0006402,200–2,800Level 380–400

> [!WARNING] > Kundun 4 and 5 have teleport abilities and area-of-effect attacks capable of wiping entire unprepared groups. Bring a large stock of HP potions and always use elemental resistance if available on your equipment.

Kundun's main drops:

  • Ancient Sets: Hyon (Dragon), Ceto (Great Dragon), Aruan (Thunder Hawk), Heras (Ashcrow), Anubis (Anubis), Chrono (Divine)
  • Jewel of Chaos, Jewel of Creation, Jewel of Guardian
  • High-level items (+9 to +13) with excellent options

Selupan Invasion

Selupan is the giant spider found in the Lorencia Tower in S6 versions. Unlike Kundun, Selupan focuses on poisonous attacks and has high resistance to magic damage.

Selupan stats (standard S6 configuration):

  • HP: 35,000,000 – 50,000,000
  • Defense: 700–850
  • Magic Resistance: 60–70%
  • Physical Attack: 2,800–3,500
  • Abilities: area poison, group teleport, minion summoning
Nota: Selupan has high magic resistance, making classes like DW and Summoner less efficient against it. DK (especially Blade Master with high-level weapons) and MG (Duel Master with mixed damage skills) perform best in this fight.

Selupan exclusive drops:

  • Jewel of Harmony (rare and highly valuable drop)
  • Ancient Sets: Gaia (Dark Soul), Broy (Venom Mist), Sylion (Sunlight), Eplate (Energy Plate)
  • Box of Kundun level 5

Important Invasion Mechanics

Loot System and Kill Assist

In MU Online S6, boss drops are generated for the player (or party) that lands the final blow — the "last hit." However, some servers implement assist systems where players who dealt significant damage also receive drop opportunities.

Standard S6 Drop Priority:
1st → Player with last hit (100% chance to participate in loot)
2nd → Parties with highest damage dealt (if assist system active)
3rd → Ground drop → collectible by any player after timer expires

Time Windows

Servers typically structure invasion schedules to ensure they are accessible across different time zones. A typical schedule example:

InvasionTime (Server)Frequency
Golden Invasion14:00 / 20:00 / 02:003x per day
Red DragonEvery 3 hours8x per day
Blood CastleEvery 2 hours12x per day
Devil SquareEvery 2 hours12x per day
Kundun20:00 / 22:00 / 00:003x per day
Selupan21:00 / 23:002x per day

> [!TIP] > Check the in-game or website event panel for live upcoming times. Kundun and Selupan invasions during peak hours (20:00–00:00) tend to attract more players, which speeds up kills but also increases competition for loot.

Class Strategies

Each of the 6 classes in S6 has distinct roles in invasions:

Dark Knight (DK → Blade Knight → Blade Master): Tank and high-impact melee DPS. Ideal for securing last hits on physical bosses like Red Dragon. Ancient sets such as Ceto and Aruan maximize damage and survivability.

Dark Wizard (DW → Soul Master → Grand Master): Long-range magic DPS. Excellent against Red Dragon and Kundun. Exercise caution against Selupan due to its magic resistance. Sets Sebone, Eplate and Heras are the strongest options.

Elf (→ Muse Elf → High Elf): Support and hybrid DPS. The most valuable role in invasion groups: heals, attack buffs and long-range bow damage. Ancient sets Gywen, Agnis, Drake and Sylion significantly boost performance.

Magic Gladiator (MG → Duel Master): Unique class with no 1st or 2nd quest. Mixed damage (physical and magical) makes it efficient against both Selupan and Red Dragon. The Chrono (Divine) ancient set is the MG's exclusive ancient armor.

Dark Lord (DL → Lord Emperor): The CMD (Command) stat enables Dark Horses and Dark Ravens as combat allies. In open invasions, a high-CMD DL deals significant area damage through its pets. Anubis and Enis (Red Spirit) ancient sets are ideal.

Summoner (→ Bloody Summoner → Dimension Master): Versatile class with summon mechanics. In invasions, summons can hold aggro or deal supplemental damage. Ancient sets Gaia (Dark Soul) and Broy (Venom Mist) are exclusive to this class.

Jewels and Post-Invasion Crafting

Invasion drops frequently include Jewels essential for crafting:

  • Jewel of Bless: Upgrades item level (+1 per use, no risk)
  • Jewel of Soul: Upgrades item option (risk of downgrade or destruction)
  • Jewel of Life: Adds an additional option to the item
  • Jewel of Chaos: Required for Chaos Combinations at the Goblin Machine
  • Jewel of Creation: Ingredient for special item creation
  • Jewel of Guardian: Used in specific pet and accessory combinations
  • Jewel of Harmony: Adds a Harmony option to an item (rare drop from Selupan)

Participating regularly in invasions is the most efficient way to accumulate Jewels without relying solely on farming regular maps.

Perguntas frequentes

Which invasion boss drops the best ancient items?

Selupan and Kundun are the main ancient set droppers. Kundun has a broader loot table covering sets like Ceto (Great Dragon), Aruan (Thunder Hawk), Heras (Ashcrow) and Chrono (Divine). Selupan focuses on high-tier sets like Gaia (Dark Soul), Broy (Venom Mist) and Sylion (Sunlight).

Are invasion schedules fixed or random?

It depends on the server configuration. In standard S6 setups, Red Dragon and Golden Invasion follow 2–4 hour intervals. Kundun and Selupan tend to be scheduled at fixed peak times such as 20:00, 22:00 and 00:00 (server time). Always check your server's live event panel.

Can the Dark Lord participate in all invasions?

Yes. The Lord Emperor (DL 3rd class) is excellent in invasions thanks to the CMD (Command) stat, which empowers Dark Horses and Dark Ravens as combat allies. DL has a special area-control advantage during open-field invasions.

What is the Golden Invasion and is it worth it?

The Golden Invasion spawns golden monsters across multiple maps simultaneously. They drop Jewels of Bless, Soul, Life and Chaos at higher rates than regular monsters. It is extremely worthwhile for Jewel farming without needing to face high-level bosses.
