MU Helper

What is the Mu Helper?

Mu Helper Interface

The Mu Helper is a tool that allows your character to automatically attack in a spot using the skills you configure. Additionally, it can pick up certain items and consume potions automatically, facilitating your progress and allowing you to play more comfortably and efficiently.

Main Functions

  • Automatically attacks in the selected spot.
  • Allows you to configure active skills (for example, combos for BK).
  • Picks up selected items (not all items are available for pickup).
  • Consumes potions automatically according to the life percentage you configure.
  • If your character moves, it automatically returns to the spot after a few seconds.

Usage Tips

  • To set a skill, activate it and click on the corresponding slot in the Helper.
  • If you are a BK and set the 3 combo skills, the Helper will execute the combo automatically.
  • Check the potions box and adjust the meter so that the Helper consumes potions when life drops to the percentage you choose.
  • The Helper is available from level 1 and is opened with the Z key.
The Helper is designed to be easy to use and accessible to all players. Activate it and start your adventure easily!

  • 5.3. Defiant Attitudes: Defiant or sarcastic attitudes towards the staff may be sanctioned if they disrupt the order or respect of the community.
6. Sanctions Policy
  • 6.1. Types of Sanctions: Warnings, temporary blocks, loss of items, character deletion, or permanent blocking of accounts, IPs, or devices.
  • 6.2. Recurrences: Sanctions will be progressively aggravated according to the severity and recurrence.

  • 7.1. Changes to the Rules: They may be modified at any time without prior notice. Notification will be given through official channels. Continued use implies acceptance of any modification.
  • 7.2. Retroactivity: Rules may be applied retroactively if continued abuse affecting the balance or integrity of the server is discovered.
8. General Abuse Clause

Mix System

โšก Mix System (Chaos Machine)

The Chaos Machine is the most important item combination system in MU Online. It allows you to create, upgrade, and transform items using Chaos, Bless, Soul, Life, and other special materials. The success of each combination depends on a percentage that varies according to the mix type and account level (VIP or normal).

๐Ÿ’ก How does it work?

  • Place the required items in the Chaos Machine (located in Lorencia).
  • Check the success rate before confirming the mix.
  • If the mix fails, you may lose the items and materials used.
  • The success rate can vary depending on the mix type and the item's level.

๐ŸŽฏ Success Rates

โœจ Talisman of Luck and Talisman of Chaos Assembly

  • Talisman of Luck: Grants an extra 10% success rate on combinations. Very useful for wing mixes and high upgrades.
  • Talisman of Chaos Assembly: Prevents the item from disappearing if the combination fails.
  • Both items can be obtained from the XShop, invasions, bosses, and special events.

โš ๏ธ Important Warnings

  • The success rate is never 100% (except for Dinorant and some special mixes).
  • If the mix fails, you can lose all the items and jewels used.
  • The maximum allowed upgrade is +15 on this server.
  • Some advanced mixes (wings, Fenrir, 380 items) have low rates: be careful!
  • Always check the requirements and the percentage before confirming.

Harmony Options

โœจ Harmony Options - Modern and Strategic System
The Harmony system in Expedition Mu has been completely redesigned to offer a more strategic, transparent, and relevant experience for all players.

What are Harmony options?
Harmony options are special enhancements you can add to your weapons and armor, granting unique advantages and powering up your gear. Unlike classic versions, now only options that truly impact the game exist.

How do they work?
Once applied, the Harmony option becomes permanently linked to the item: it cannot be removed or restored. This encourages strategic decision-making and gives value to each choice.

How are they obtained?
  • Refining Stone (Lower and Greater): Obtained by selling any rare item to any sales NPC in the game (except in Aida).
  • Harmony Options: Primarily obtained in Kanturu Relics, with the Refinery event being the most important source.
  • Gemstone: Can drop in Dungeons and from some bosses. It is refined into a Harmony jewel after completing the Kanturu Remain event and speaking with the NPC Elpis. The success rate is random.

Trade and Economy:
Items with Harmony options can be freely traded among players, allowing for a dynamic and strategic economy.

Explore the new Harmony options and take your gear to the next level with the most modern and balanced system in Expedition Mu!

Solution:
  • Use the force move option from the web panel (if available).
