Gens is MU Online's two-team "family" system, and it is all about PvP (that means player-versus-player fighting). You pick one of two families, fight the other family to earn Contribution Points (your score in this system), and climb a ranking ladder. The top players grab rewards every month. This guide shows you how to join, how to rank up, and whether Gens is worth your time.
What is the Gens system?
Gens (short for "Gens Family") is a PvP team system built on top of the normal MU Online world. It is permanent and it covers the whole server. Instead of everyone fighting everyone, each player joins one of two rival families and fights for it.
The point is simple. You earn Contribution Points (your Gens score) by beating players from the other family. Then you climb the ranking ladder and prove your family is on top.
Gens has its own war map called Vulcanus, its own ranking ladder, and rewards that come out once a month. It runs at the same time as everything else you do in MU. So you can level up, farm jewels (the gems you use to upgrade gear) and join Castle Siege (MU's big guild-vs-guild battle), and you still earn Gens points any time you fight a rival.
You never "finish" Gens. You join a side and keep earning points for as long as you want the rank and the rewards. If you mostly play PvE (that means fighting monsters, not other players), you can still join for the story and the free rival kills. Just know that the best rewards go to players who fight a lot.
Duprian vs Vanert: the two factions
There are only two families to choose from, and the difference between them is mostly story, not power. A "faction" just means one of the two families you can join.
- Duprian is led by Duprian Winston. The story paints this family as one of the most heroic and noble bloodlines in MU Online.
- Vanert is led by Vanert Reicht, a rival who fights against Duprian's rule.
In terms of gameplay, the two families are mirror images of each other. Neither side gives you a stat bonus, better gear, or a class advantage. So you will not weaken your character by picking the "wrong" one.
Because of that, most players just join whichever side their guild and friends are on. You can only be in one family at a time. Your guild members and party members all have to be on the same side as you.
Your guild and party members all have to be in the same Gens family, so talk to them before you lock in. If you join the opposite side from your guild, you cannot party up with them in the war zone. Pick your class for fun, but pick your Gens family for teamwork.
How to join via the Gens NPC
Joining is quick once you hit the right level. An NPC is a computer-controlled character in town that you talk to. Here is the classic way to do it:
- Reach Level 50. This is the normal level you need on official-style servers. Some private servers (player-run copies of the game) lower it or drop it, so check your own server's rules.
- Go to the Gens Steward NPC for the family you want. The Vanert Steward (Reicht) stands in Noria, and the Duprian Steward stands in Lorencia.
- Talk to the steward and say yes to joining. You cannot be in both families, so once you confirm, you are stuck on that side until you officially leave.
The map spots (coordinates) for these NPCs are slightly different from one source or game version to the next. Use the table below as a starting point, then just look around town for the NPC if the exact tile is a little off:
| Faction | Steward NPC | Town | Webzen coords | MU Online Fanz coords |
|---|---|---|---|---|
| Vanert | Vanert Reicht | Noria | 167, 100 | 126, 113 |
| Duprian | Duprian Steward | Lorencia | 144, 127 | 145, 129 |
Official Webzen and the site MU Online Fanz list different map tiles for the same NPCs, and the numbers can change with each season or game version. Treat these numbers as a hint and just check where the steward really stands in your own town. If you are still working your way up to Level 50, the leveling guide will get you there faster.
Earning Contribution Points
Contribution Points (CP for short) are the core of Gens. Your rank and your rewards all come from how many you collect. There are two main ways to get them:
- Killing rival players. On classic servers, each time you kill a player from the other family you get +5 Contribution Points. The big thing here is that this kill does not turn you into a PK. (PK means "player killer," and it tags you as an outlaw with penalties.) Gens kills are official faction fights, not murders, so you stay clean.
- Gens daily quests. You can grab extra points from Gens quests. These usually come from the Mercenary Guild on certain days (often Wednesdays and Saturdays). The days and the quest-giver can change by version, so double-check on your server.
There are also rules that stop you from farming points the easy way. ("Farming" just means doing the same thing over and over to pile up rewards.)
- Death penalty: MU Online Fanz says that getting killed by a rival player costs you -3 Contribution Points. Not every season uses this rule, so on some servers only your kills count and your deaths are ignored.
- Anti-farm rule: killing the same player over and over gives you no extra points. You have to spread your kills across lots of different rivals to keep scoring.
Most of the serious point-farming happens on the Vulcanus battle map, the Gens war zone for this system. Inside Vulcanus, players on the same side cannot attack each other, so every fight is family-versus-family.
| Action | Classic point value | Notes |
|---|---|---|
| Kill an opposing-faction player | +5 | No PK status; main repeatable source |
| Killed by an opposing-faction player | -3 | Per Fanz; some servers ignore this |
| Kill the same target again | 0 | Anti-farm rule |
| Gens daily quest (Mercenary Guild) | Varies | Scheduled days, commonly Wed/Sat |
The +5 per kill, the -3 death penalty, and the quest days are all official-style values. Private servers often change kill points, death penalties, quest days, and what the rewards are. So always check your own server's Gens rules before you start grinding (grinding means playing for a long time to build up points or loot).
Rank tiers and ranking
Gens has two different rank systems, and knowing the difference helps a lot:
- General Ranks work on fixed point goals. You earn them just by reaching a set number of points. Everyone who hits the number gets the rank, and you are not competing with anyone.
- Leadership Ranks work by comparing you to other players. Only the top 300 point earners in your family qualify. Your rank depends on your spot in that list, not on a set score, so you are racing the people on your own side.
Here are the classic General Ranks, from lowest to highest, with the points you need for each one:
| General Rank | Contribution Points required |
|---|---|
| Private | Default (on joining) |
| Sergeant | 500 |
| Lieutenant | 1,500 |
| Officer | 3,000 |
| Guard | 6,000 |
| Knight | 10,000 |
The Leadership Ranks sit above the General Ranks. They are only for the top 300 point earners in each family. Which one you get depends on your exact spot in that top 300:
| Leadership Rank | Position in faction |
|---|---|
| Grand Duke | Rank 1 |
| Duke | Ranks 2–5 |
| Marquis | Ranks 6–10 |
| Count | Ranks 11–30 |
| Viscount | Ranks 31–50 |
| Baron | Ranks 51–100 |
| Knight Commander | Ranks 101–200 |
| Superior Knight | Ranks 201–300 |
So a steady PvE player can reach Knight just by grinding up to 10,000 points. But becoming a Grand Duke or Duke means scoring more points than almost everyone else on your side. The point goals and the 300-player limit are official/Fanz values, and private servers change them often.
Faction rewards and benefits
Here is the thing that surprises new players: only Leadership Rank holders get monthly rewards. Reaching a General Rank like Knight gives you a cool title and counts as progress, but it does not pay out by itself. To earn the monthly prize, you have to break into your family's top 300.
You claim rewards during the first week of each month from the Gens Steward. Just talk to the NPC and pick dialogue option 6. The better your Leadership Rank, the bigger the prize:
| Leadership Rank | Example monthly reward |
|---|---|
| Grand Duke | Shining Jewelry Case x30 |
| Superior Knight | Old Jewelry Case x3 |
The cases open up into jewels or Zen (Zen is the in-game gold). That loot goes straight back into your gear, your Chaos Machine crafting (the in-game machine you use to combine and upgrade items), and the wider jewel economy. On top of the loot, Gens gives you a few handy perks:
- No-PK PvP against rivals, so you can fight out in the open without getting tagged as an outlaw.
- Teamwork for guilds and parties that are all on the same side.
- Fancy titles like Grand Duke that show everyone you are a top player.
The Shining and Old Jewelry Case amounts and the first-week claim window are official-style defaults. Private servers often swap in their own items, Zen packs, buffs (temporary stat boosts), or special seasonal prizes, and they may change when you can claim. Read your own server's Gens reward list before you chase a rank.
Killing the rival faction for points
Beating players from the rival family is the main way to keep earning Contribution Points, and it is where most of your grind happens. The rules reward smart, aggressive PvP where you spread out your kills:
- +5 per rival kill with no PK penalty. This pushes you to fight out in the open world and in Vulcanus instead of holding back.
- Staying alive matters. If your server uses the -3 death penalty, dying to rivals eats into your score. So playing smart beats trading kills back and forth carelessly.
- Spread your targets around. Killing the same player again gives you nothing, so you score the fastest by hunting lots of different rivals instead of camping one player. (Camping means waiting in one spot to kill the same enemy over and over.)
If you are building a character just to crush Gens PvP, your class and your stat setup matter a lot. The best PvP classes guide and the stat builds guide will help you build a character that wins fights in Vulcanus. The PvP server guide covers servers built around this kind of fighting.
Why farm rival kills
- +5 points each, and you never become an outlaw
- Quick progress toward General Ranks
- Fits right in with everyday PvP and Vulcanus
- Helps your whole family climb the ladder
What slows you down
- Dying to rivals can cost points (depends on the server)
- Killing the same target again gives zero points
- Leadership rewards need a top-300 spot
- A big gear gap can make fights one-sided
Switching factions: cost and penalties
You are not stuck with your first choice forever, but switching costs you a lot. One rule is the same in every source: leaving any Gens resets your Contribution Points to zero. ("Reset" means it wipes your score back to nothing.) That erases all the points you built up and the rank that came with them.
To change sides, you first have to officially leave your current Gens through the steward. Only then can you join the other one. What happens next depends on your server:
- The official guide text suggests you can join a Gens again after you leave.
- Some versions let you re-join right away. But many private servers make you wait out a cooldown (a forced waiting period) before you can sign up with the rival family.
Switching families means your Contribution Points and rank go back to zero. If you grinded all the way to Knight or a Leadership Rank, leaving throws all of that away. Only switch if your guild is moving sides, or if you really want a fresh start. And check first whether your server makes you wait on a timer before you can join the rival family.
Is Gens worth it for PvP and PvE?
For PvP players, Gens is almost a must. It turns normal open-world fights into points, gives you free kills against a whole enemy family with no penalty, and adds a prestige ladder on top of Castle Siege. If you already love fighting other players, joining a Gens is pure bonus. The Castle Siege scene and the Gens war usually share a lot of the same players.
For pure PvE players, it is a closer call. You still gain from the daily quests and the odd rival kill, and the monthly cases are real loot. But the big rewards need a top-300 spot, and that mostly comes from PvP. If you mainly grind events and bosses, treat Gens as a small bonus, not a main goal.
Either way, Gens is best on a busy server with lots of players. You can find one on the live MU Online ranking and through the main best private servers guide. If you want PvP-heavy worlds, check out PvP servers and balanced PvP servers.
Frequently asked questions
What level do I need to join a Gens?
On classic servers you need to reach Level 50, then talk to the Gens Steward NPC for the family you want (Duprian in Lorencia or Vanert in Noria). Some private servers lower the level or drop it completely, so check your own server's rules before you head to town.
Is Duprian or Vanert better?
Neither one is stronger. The two families are mirror images, with no built-in stat, gear, or class advantage, so on official-style servers the only real difference is the story. Pick the side your guild and friends are on, since guild and party members all have to be in the same family.
How do I earn Contribution Points fastest?
Kill players from the other family (classic value is +5 points each, and you do not become a PK), and spread your kills across different players, because killing the same one again gives nothing. Then add the Gens daily quests from the Mercenary Guild on its set days. Most point-farming happens on the Vulcanus battle map.
Do I get PK status for killing rival players?
No. Killing a player from the other family through the Gens system is an official faction kill, so it does not tag you as a PK or an outlaw. That is what makes Gens such a friendly way to do open-world PvP, instead of getting punished for killing random players.
What rank do I need to get rewards?
Only Leadership Rank holders (the top 300 point earners in a family) get the monthly rewards. You claim them in the first week of each month from the Gens Steward by picking dialogue option 6. General Ranks like Sergeant or Knight are titles and milestones, but they do not pay out on their own.
What happens if I leave or switch factions?
Leaving any Gens resets your Contribution Points to zero and wipes out all your rank progress. You have to leave through the steward before you can join the other side. Some versions let you re-join right away, while many servers make you wait before you can join the rival family. So only switch if you are ready to start over from scratch.
