MU Helper
The automatic farming assistant: what it does, what it does not do, what it costs and how to set up each tab.
Updated on August 10, 2026The MU Helper is the autopilot built into the client. With it on, your character picks targets, attacks, keeps buffs up, drinks potions, picks items up off the ground, repairs equipment and walks back to the starting point if it strays too far. It is official, it is part of the game and it charges zen for time spent using it.

The cycle, in exact order
The helper runs a cycle every 250 milliseconds, always in the same order. Any step that fails aborts the whole cycle, and that explains a common behavior: if it cannot cast a buff, it never gets as far as attacking.
- 11. Pet
Activates the raven, if it is configured.
- 22. Buffs
Casts whatever is missing in the three buff slots.
- 33. Recover health
Heal, Drain Life or a potion, according to the threshold you set.
- 44. Pick up items
Applies the filters from the Obtaining tab.
- 55. Regroup
Walks back to the point where you turned the helper on, if it is too far away.
- 66. Attack
Picks the target and the skill.
- 77. Repair
Fixes equipment below 50% durability.
The three tabs
- Three attack slots: one basic one always active and two conditional.
- Three buff slots, which it keeps up on its own.
- Condition for each conditional skill: by timer (every X seconds) or by situation (2, 3, 4 or 5 enemies nearby, or an enemy hitting you).
- Combo mode, which cycles through the three attack slots in sequence.
- Hunting radius and maximum time away from the starting position before coming back.
- Counterattack against anyone shooting from a distance and automatic return to the starting point.
- Pickup radius.
- Ready made filters: zen, jewels, ancient and excellent.
- Pick up everything, for when you do not want to filter anything.
- A list of up to 12 name fragments: it picks up any item whose name contains one of them.
- Auto heal: health threshold in percent for healing and for drinking a potion.
- Party support: heal members below a health threshold.
- Raven: idle, attacking on its own or attacking along with you.
- Repair equipment automatically.
- Self defense against players who attack you.
- Auto accept party from friends and guild members.
What it costs
The helper charges zen every 5 minutes, and the amount depends on your total level and on how long the session has been open. Every 200 minutes of continuous use, the multiplier goes up one step.
| Step | Session time | Multiplier | Cost per 5 min for a total level 800 character |
|---|---|---|---|
| 1 | 0 to 200 min | 20 | 16,000 zen |
| 2 | 200 to 400 min | 50 | 40,000 zen |
| 3 | 400 to 600 min | 80 | 64,000 zen |
| 4 | 600 to 800 min | 100 | 80,000 zen |
| 5 | above 800 min | 120 | 96,000 zen |
The math is `multiplier × (level + master level)`. Without enough zen, the helper does not turn on and tells you how much is missing. Turning it off and on again resets the step, which in practice makes short sessions cheaper than one long session.
Farming with your character disconnected
There is the `/offlevel` command. With the MU Helper already on and your character alive, it disconnects your client and leaves a ghost character on the map continuing the cycle with your settings. When you log back in, the ghost is closed out before character selection.
/offlevel
The two buff lists, and what that breaks
Inside the client there are two separate lists deciding different things about buffs. One says what shows up for you to choose; the other says what the helper actually knows how to cast. When the two disagree, the result is confusing.
| Situation | What happens in practice |
|---|---|
| The skill is on both lists | it works: you choose it and the helper keeps the buff up |
| Only on the interface list | you can choose it and nothing happens |
| Only on the engine list | it would work, but it does not show up to be chosen |
There is also a safety net: every 120 seconds the helper forces a recast of the buffs, even when it thinks they are active. That exists because the client's buff list is filled by packet and, if the removal message gets lost, it would think the buff lasts forever.
What it does not do
- It does not change maps or look for a better spot. It stays where you turned it on.
- It does not sell at the NPC or manage a full inventory. A full inventory stops the pickup.
- It does not enter events or do quests.
- It does not replace a party: it heals and supports if you tick the option, but it coordinates nothing.
- Skills flagged in the client's data file as master or master level skills do not go into its list.
