Zen and WCoin are the two currencies that drive the entire MU Online economy, and the good news is that you can build up huge amounts of both without taking a cent out of your pocket. Zen is the classic in-game currency, used to repair items, buy consumables, upgrade equipment and trade with other players. WCoin (also called WCoinC or "cash") is the premium currency, normally bought with real money in the Cash Shop, but which also circulates for free through events, voting and reselling. In this tutorial you'll learn, step by step, how to turn play time into real wealth inside the server, without relying on your wallet. The focus is the free-to-play player who wants to compete on equal footing with those who pay.
First of all, understand a truth of the MU economy: whoever controls the supply of items and jewels controls the Zen. Farming for hours doesn't help much if you sell everything to the NPC. The secret lies in reselling to other players, taking advantage of events and never wasting drops. Let's break down each front.
Before you start
Before you head out farming, prepare the ground so every hour of play yields as much as possible. Some points are universal, others vary by server, so always check the rules and the Cash Shop of your specific server.
- Find out the server's rates. Servers with high drop rate and Zen rate fill your inventory much faster. This completely changes which methods are worth it.
- See if there's a voting system. Most private servers give WCoin or points for voting on ranking sites (like XtremeTop100, GTop100). This is the number one source of free WCoin.
- Check the Cash Shop. Know what you can buy with WCoin. That way you aim to earn exactly the WCoin needed for the items you want.
- Reserve space in your inventory and Vault (chest). Efficient farming demands space. A full inventory forces you to stop and return to town all the time.
- Have a farming character. Classes with area damage (like Dark Wizard and Dark Lord with Fire Scream) clear groups of monsters fast, ideal for stacking drops.
With the base ready, let's cover the Zen-earning methods first, then WCoin.
Method 1: Farm monsters on the right maps
The most direct way to earn Zen is by killing monsters — but where you kill makes all the difference. Each monster drops an amount of Zen when it dies, and monsters on higher maps drop far more. The golden rule is: farm on the most advanced map you can clear quickly and safely.
Follow these steps:
- Level up until you can survive in maps like Atlans, Tarkan, Aida or Kanturu (availability varies by server).
- Choose a spot with high monster density, so you don't waste time walking.
- Use area skills to kill several monsters at once.
- Pick up the Zen on the ground and, above all, every item that drops.
- Return to town when the inventory fills up and repeat.
The raw Zen from monsters is good, but the real profit lies in the items they drop during farming. Never ignore drops just because they look like "junk": many are useful for the next method.
Method 2: Reselling drops in the Personal Shop
Here is the trick that separates the poor player from the rich one. Selling items straight to the NPC pays very little. The Personal Shop (usually activated with the server's corresponding key) lets you set up a stall and sell to other players at the price you set.
What to resell with a good margin:
- Jewels: Bless, Soul, Life, Creation, Chaos and Harmony are always in demand for upgrading and creating items. Never sell a jewel to the NPC.
- Excellent items: equipment with excellent options is worth much more than common items.
- Wings and old items (Ancient): old sets with the full set have high value.
- Event items: pieces that only drop in specific events are coveted.
Step by step to sell well:
- Set aside in your inventory only what you're going to sell.
- Go to a busy area (usually the main town, like Lorencia or Elbeland).
- Open the Personal Shop and drag the items into the slots.
- Set realistic prices — watch what other players are charging for similar items.
- Put an eye-catching name on the shop and leave the character standing there selling while you do something else.
This is the most stable form of passive income in MU. Many players keep a "seller" character standing in town 24 hours a day.
Method 3: Free WCoin from voting and website events
WCoin, despite being a premium currency, is fully accumulable for free on most private servers. The two main sources are voting on ranking sites and events run by the server.
Voting: go to the server's website, look for the "Vote" or "Votar" section, and vote on the listed ranking sites. For each vote you usually earn a fixed amount of WCoin or points, with a daily limit. Do this every day — over a month, it adds up to a lot. The value per vote and the frequency vary by server.
Website and Discord events: many servers give WCoin for taking part in giveaways, promoting the server, referring friends (referral system) or completing weekly tasks. Keep an eye on the official announcements.
Method 4: In-game events that give valuable rewards
The events inside the game are gold mines for both Zen and resellable items. Taking part in them yields jewels, reward boxes and rare items that you turn into Zen in the Personal Shop.
Classic events worth doing (availability varies by server):
- Blood Castle: delivers jewels and items when completed within the time limit.
- Devil Square: great for experience and Zen drops.
- Chaos Castle: the last survivor takes good rewards.
- Golden Invasion: the golden monsters drop Excellent items and jewels.
- Boss spawns: bosses like Kundun and Selupan drop extremely high-value items.
Build a daily routine that hits the events with the best rewards. Consistency beats luck.
Method 5: Chaos Machine and upgrading for profit
The Chaos Machine (with the Goblin NPC) lets you combine items and jewels to create higher-value equipment. With practice, you buy cheap materials, combine them and sell the result for much more. It's a "craftsman" method that requires understanding the success rates, which vary by server. Start with low-risk combinations before risking expensive items.

Common errors
| Error | Consequence | How to avoid it |
|---|---|---|
| Selling jewels to the NPC | Loses a lot of Zen | Always use the Personal Shop |
| Ignoring daily voting | Free WCoin thrown away | Vote every day on the site |
| Farming on too weak a map | Poor Zen and drops | Move up to the highest viable map |
| Inventory always full | Loses drops on the ground | Return to town frequently |
| Buying currency outside the game | Risk of scam and ban | Earn everything inside the game |
| Not taking part in events | Loses rare items | Build a daily event routine |
Final tips
Earning Zen and WCoin for free in MU Online is entirely possible, but it takes discipline and method. The free-to-play player who wins is the one who treats the economy as part of the game: farms on the right maps, never sells a jewel to the NPC, keeps an active Personal Shop, votes every day and shows up to the events with the best rewards. Add all that up over weeks and you'll have wealth that rivals those who spend real money.
Start small, build your jewel stock, leave your seller standing in town and make voting a daily habit. To dig deeper into builds and farm routines by class, explore our gameplay guides and keep adjusting the strategy according to your server's rates. Remember: in MU, patience and organization are worth more than your wallet.
Frequently asked questions
Can you play MU Online competitively without spending anything?
Yes. Many strong players are 100% free-to-play. Zen is farmed by playing and free WCoin comes from events, quests and voting on the website. Spending money speeds things up, but it isn't required to progress well, especially on medium and high rate servers.
What is the fastest way to earn Zen at the start?
Farming monsters on the highest map your character can safely handle and reselling the useful drops (jewels, Excellent items, old wings) to other players. Selling straight to the NPC pays little; the Personal Shop earns far more.
Does voting WCoin disappear if I don't use it?
It doesn't disappear, but it depends on the server. In general the WCoin earned from voting goes straight to your account and stays accumulated until you buy something in the Cash Shop. Always check the server's rules, because vote deadlines and limits vary by server.
Is selling jewels like Bless and Soul worth more than selling to the NPC?
Much more. The NPC pays a low fixed value, while players pay in Zen (or trade for items) well above that, because they need the jewels to upgrade equipment. Setting up a Personal Shop with jewels is one of the most stable passive incomes in the game.
Is it safe to buy Zen or WCoin from other players outside the game?
I don't recommend it. Trading currency outside the game usually violates the rules and is the main source of scams and account bans. Prefer to earn everything inside the game through the legitimate methods described here; it's slower, but your account stays safe.
