MU Origin 3 Class Guide: An In-Depth Look At Primary and Secondary Classes

MU Origin 3 has been expected to continue the success of its predecessors and bring in even more features and content that stimulate a deeply immersive experience for new and returning players alike. From deciding on a character class and creating your hero down to taking on quests of all sorts and sizes, the perilous yet rewarding adventures has a lot of contributing factors that make it a unique and unforgettable journey.

Naturally, the core of what makes the adventure fun and exciting centers around the character you choose and choose to build. Despite having only a trio of main classes to choose from in MU Origin 3, the various ways each one can be built provides more than enough customization options for players to really create their own unique hero akin to their preferences and play style.

It is in this sense that we cannot absolutely consider one class or subclass as entirely and absolutely superior to others given that each main class, as well as their variants, can excel in one of the many types of challenges that lurk within the continent of Mu.

If you have just started your adventure in MU Origin 3 and most especially if you have not played any of its earlier incarnation, we highly recommend that you peek into our MU Origin 3 Beginner’s Guide first. Our beginner’s guide takes you through all of the game’s basic content along with some tips and strategies to help you strengthen you character and take on the different challenges ahead of you faster and more efficiently.

Although we have already touched on the basics of each main class in our earlier guide, suitable enough to help you decide which one should be your main character, we will be diving deeper into the main classes as well as each of the available subclasses to help you strategize on how to build around them better.

Just as there are no right or wrong choices as far as choosing the main class is concerned, building your hero’s stats and skills in relation to your chosen secondary class is also dependent on your preferences and play style. No perfect build exists that caters entirely to a group of players with varying needs and preferences but at least knowing the basics and core concepts surrounding each class will help you build your ultimate character better.

MU Origin 3 takes you through a series of class upgrades before you can finally be made to choose between the 2 secondary classes applicable to the main class you chose. Starting with the P1 rank, you will have to reach level 100 and fulfill 4 other requirements to be eligible for a class upgrade. Once you reach rank P4, the important decision of choosing between the 2 classes will present itself to you at the class altar and how you build your character from then on should be more in sync with your choice of secondary class.

As we mentioned in our beginner’s guide, though, you can always prepare in advance for the role you want to take on starting with how you distribute stat points you earn. By default, stat points are allocated automatically under your character profile and you will have to set it to manual if you want to distribute stats on your own with each new level reached. However, you can always reset stats for free before reaching level 100 in P3, or through spending some gems beyond that.

While an entirely manual allocation of stat points ensures that every point you distribute aligns with your desired character build, it will not be very convenient to do so each time you level up, especially at the rate at which you reach new levels early in your adventure.

Instead of choosing a manual allocation of stats early on, you can just leave it be and reset before reaching max level of P3 to do so for free. The important concept to grasp early on is that you should already have a solid idea in mind of what stats to prioritize over others along with the secondary class build you plan on going for before you even reach P4.

Although we will be laying out some basic skills and their effects just to give beginners a good idea of what to expect from each main class, we will not be delving into the plethora of ultimates you can assign to each skill of your choice. Remember that you can only equip 5 active skills at a time in MU Origin 3, but each one can essentially be customized by your ultimate of choice for each skill.

Potential will loosely be similar across characters once you earn sufficient resources to unlock and upgrade them but the going idea as you earn the needed resources is to prioritize some of these passive boosts depending on the subclass of your choice. Decision on which types of gears to prioritize, attributes to consider, and even companion choices, can each be aligned to your chosen character build as well.


mu origin 3 swordsman

Typically the first pick for beginners and close combat players alike, the Swordsman is the only melee fighter in MU Origin 3. As expected, Swordsmen are prone to taking more damage than the other main classes given that they will always have to be within the reach of every enemy while they attack and perform their skills. Swordsmen, however, are built for survival against continuous damage with high defense and HP stats much more than any other character class.

Comparable to the most basic character classes in most other RPGs, Swordsmen have very straightforward gameplay. Just because they have the best defensive capabilities does not mean that they cannot dish out heavy damage. It is just that swordsmen are built to have little to no added effects to the skills they use other than further increase their defensive strength and bolster team HP. They can inflict bleed damage and can boost critical rates and damage, but as far as crowd control skills are concerned, they have practically zero.

STR or strength comes as a basic necessity for the Swordsman, giving him additional Physical Attack and Physical Damage Increase with each additional point allocated. While Swordsmen may exhibit some skills that may appear to utilize something other than physical strength, each one of them is actually dependent on the Swordsman’s STR stat.

In contrast with STR, Swordsman have little to no use for INT or Intelligence. Although allocating some stats for INT will raise the Swordsman’s Accuracy Level, the value that other stat choices provide is more beneficial to the Swordsman regardless of its build. While it is okay to spend some stat points on INT for your Swordsman, be sure to consider the overall build and just how much additional levels of accuracy you need.

DEX or Dexterity provides 2 benefits for the swordsman as it increases both his Evasion Rate as well as his Excellent Strike Chance. Evasion Rate still hinges on chances and probabilities with each attack you receive while Excellent Strike Chance also relies on luck to visually see its impact on the attacks you make. In any case, DEX is an important stat choice to invest in for players who want to have a more offensive build for their Swordsman.

Last but not the least is STA or Stamina, which not only increases the Swordsman’s HP but also provides increases in both Physical Damage Negation and Magic Damage Negation, ultimately leading to higher defense capabilities. As the designated tank of the 3 base classes, STA is certainly an important stat for the Swordsman’s general build.

mu origin 3 fighter

Fighters stand as the DPS build of the Swordsman and should be the better choice for players who enjoy more of MU Origin 3’s solo content as well as its PvE dungeons. With more stats allocated towards STR and DEX, Fighters tend to sacrifice a bit of HP and defensive capabilities for higher numbers in the damage that their skills inflict.

Beyond raw damage, Fighters can best utilize their DPS potential with skills that enable berserk status, inflict bleed damage, as well as skills and enhancements that boost both critical rate and critical damage. There are no right or wrong ratios of stat points and skill ultimates to consider for bolstering defense in exchange for a missed opportunity to pump damage numbers further.

However, if you are building a Fighter who prefers to charge in and eliminate targets before they knock you out, Fearless Charge and Crash ought to be among the skills that you have equipped and ready to quickly close the distance between you and your enemy.


mu origin 3 knight

In contrast with the Fighter secondary class, the Knight is more attuned to filling in the tank role, boosting HP and defense even further but sacrificing some opportunity to deal extra damage. The key to a Knight’s survivability does not end with merely having high amounts of health points as well as astounding levels of physical and damage negation. Knights have abilities that can have him earn a percentage of HP with some skill attacks as well boosting survivability not just for himself but for his allies as well.

Considering the 4 stat choices, going for the Knight subclass gives a bigger amount of focus on STA rather than DEX. If you have high HP and DEF, then you definitely do not need increasing your dodge rate and if only one of the 2 perks of DEX are useful to you, then you might as well go for more stat points allocated on STA and STR.

Just like how ultimate skills can be chosen and attuned to the skills of the Fighter to boost his damage, there are alternative ultimates that are more compatible with the Knight. Ultimates can also boost DEF and increase HP with its use, so be sure to look into these perks as you choose the skills to equip on your Knight.

While Fighters are deemed more favorable for players who want to progress quickly on their own as well as dominate MU Origin 3’s PvE content, we recommend a Knight for PvP as well as team or coop dungeons. With the plethora of strong enemies across the continent of MU, there is hardly anything that should keep you from banking on defensive investments, most especially for team plays and other multiplayer cooperative game modes.


mu origin 3 mage

Mages have always been regarded as the fastest farmer in most conventional RPGs. Specializing in AoE attacks or skills that deal a lot of damage to multiple enemies at once, Mages will rip through mobs faster than any other class in the game. Though Mages do have long range skills and attacks, they still fall behind the archer in terms of attack reach.

In terms of defense as well, Mages are often known to be rather lacking. It is still a fair trade off for mage-users, though, as the core idea of utilizing mages revolve around the concept of stopping enemies in their tracks before they come near you.

Mages in MU Origin 3 are not just masters of AoE damage but they can be groomed as well to be the best in crowd control. Mages can trade some points of damage in their build to consider added status effects in their attacks and can be very helpful in team battles as a means of weakening and incapacitating enemies in both PvE and PvP.

In almost all incarnations of the game, Mages will comparatively be a challenging character to use on auto mode early in the adventure, but will eventually become the best one as far as idle farming or auto battles are concerned.

While both DEX and STA work the same way for Mages, it is to be expected that they will require INT over STR. Mages only deal magic damage and every stat point invested into INT improves Magic Attack and increases Magic Damage. In contrast with Swordsmen as well, Mages will hardly require stat points on STR although doing so will improve their rate of accuracy.

Mage Skills

Meteor Call – summons a meteor to deal 150% damage to enemies in targeted area and has CD of 4 seconds.

Black Dragon’s Realm – continually hits surrounding enemies in a large are with 210% damage and has a CD of 6 seconds.

Storm Cyclone – launches a cyclone that travels forward, dealing 210% damage to enemies in its path, inflicting slow on them for 3 seconds and has a CD of 12 seconds.

Time Blink – lets the Mage teleport for a short distance, inflicting 180% damage to his target area and has a CD of 12seconds.

Auroric Ray – fires a beam of light in front of the mage, dealing 350% damage to enemies in its path and has a CD of 15 seconds.

Palm Thunder – calls forth a thunder that strikes a single enemy for 400% damage.


mu origin 3 magister

Mages certainly are a challenge to handle for beginners especially when reaching latter challenges or game modes that require you to stray from auto mode. Despite being very capable of dishing out huge damage outputs against several enemies at a time, Mages are often in positions where they are likely to take some damage as well.

The Magister, as a secondary class for the Mage, further increases his damage outputs to minimize instances where enemies can go near them. Though the Magister can still have some added effects to the spells they cast on their enemies, a more solid build should be aimed towards maximizing their raw damage output. If you are familiar with the concept of glass cannons, then the Magister certainly comes closest to the idea of the build.

Magisters have the potential of becoming an ace in terms of farming and rushing through a lot of the daily activities that you need to plow through in MU Origin 3. However, due to the lack or absence of crowd control effects to their skills as well as the relatively low defensive capabilities, Magisters are certainly difficult to manage in PvP content as well as cooperative adventures that require diversity.

With the value of increases in damage outputs, you will naturally want to push for considering every stat point earned towards increasing INT, save for the minimum stat requirements that come with the gears you want to equip. Between DEX and STA, the better choice is DEX to build up Excellent Damage Rates as against pumping up HP as well as Physical and Magic Defense rates.

Forbidden Mage

mu origin 3 forbidden mage

The Forbidden Mage is the dominant force when it comes to inflicting negative status effects on its enemies. Choosing the Forbidden Mage over the Magister will net you a Mage with lower damage outputs as far as raw damage is concerned but the added effects you can incorporate in its skills can more than make up for the lack of DPS numbers in various scenarios.

While Magisters can still take damage against enemies that make it through its barrage of DPS spells, Forbidden Mages specialize in ensuring that once its attacks hit an enemy, they will take and push to maintain advantage in combat. Slowing down and freezing enemies in its tracks are just some of the ways Forbidden Mages can turn the tide of battle and while these crowd control attributes are best appreciated in PvP combat and game modes, they are also quite useful in many PvE challenges.

Forbidden Mages do still need to prioritize investing in INT over all other stats, but they do not necessarily have to invest in DEX for the extra chance of dealing more damage. Instead, a build towards capitalizing on survivability an gaining advantage in lengthy combat is more advisable, leading to a build that considers some stat investments in STA.


mu origin 3 archer

The character class with the farthest range in MU Origins 3 also has the top potential of inflicting the most damage against any single target. Archers, just like Fighters also have some AoE attacks but as far as skill types are concerned, the Archer’s number and strength of AoE attacks are somewhere between the other 2 character classes. While archers do have superb offensive strength and is a dominant force in terms of range, they are also almost as easily squishy as mages are in terms of defense and health.

While Archers can be built to become very effective boss hunters and dominant single target eliminators, they are also exclusively the only class that can provide healing for themselves and their party. Both subclasses of Archers in MU Origin 3 can dish out decent damage and can stand on their own fairly well but its support class version is certainly one of the most welcomed member of any party for important cooperative game modes and challenges.

Although Archers rely on agility or DEX to increase their attack damage and attack speed in earlier incarnations of the game and also invest in INT to improve their healing abilities and support spells, the stat benefits of Archers in MU Origin 3 work very much like that of the Swordsman, where allocated points on STR improve attack damage and points invested in INT only improve accuracy rate. Likewise, it is important to note that both DEX and STA work the exact same way across all main classes.

Archer Skills

mu origin 3 archer skills

Multi-Shot – unloads numerous arrows in an arc ahead, each dealing 150% damage to enemies and has a CD period of 4 seconds.

Meteor Hail – shots arrow above to rain down on enemies in an area dealing 240% damage and has a CD of 6 seconds.

Rapid Shot – fires a stream of arrows on enemies ahead dealing 250% damage to targets and has a CD of 12 seconds.

Evade – lays down a land mine and rolls forward to evade. The mine deals 180% damage and the skill has a CD of 12 seconds.

Piercing Strike – charges and lets loose an arrow that pierces through all targets ahead, dealing 250% damage and has a CD of 15 seconds.

Summon War Pet – calls forth Barry who inherits her attributes and has a CD of 30 seconds.

Fire-at-Will – launches a series of arrows on enemies and deals 350% damage.

Holy Archer

mu origin 3 holy archer

The Holy Archer comes off very differently from what veterans of the earlier MU incarnations might expect as a support character. Contrary to the previous conventional builds of Fairy Elves where they basically only heal and buff allies as well as invest in INT over DEX, as the previous stat that increases the archer’s damage outputs, Holy Archers in MU Origin 3 are designed to be able to stand on their own.

Holy Archers are the more complex subclass of the 2 and while you may still consider STR as your priority stat to boost her damage outputs, you should also consider investing some points in STA to increase your own survivability as well as complement your supposed skill choices’ effects. For one, The Summon War Pet is certainly a choice skill for the Holy Archer while the same will probably be never considered by a Ranger.

With spell effects that replenish health, a Holy Archer can benefit from having a high enough amount of HP. Likewise, since the War Pet’s main purpose is to take enemy aggressiveness away from the Holy Ranger, it also benefits from his summoner’s HP as he reflects the same amount once summoned. Keep in mind that Holy Archers do not just heal as they can also have skills that bolster offensive strength and defensive capacity.


mu origin 3 ranger

Just like the Fighter subclass and the Magister subclass, the Ranger subclass for Archers is very much straight to the point and very simple to handle and manage. Rangers capitalize on their burst damage capabilities and can aim to eliminate enemies one-by-one at the fastest rate. Naturally, STR will be the main stat to work on as raw damage output is certainly the priority effect.

Contrary to the stat point distribution performed by auto mode early in your adventure, the ideal build for Rangers is to invest as many stat points on STR while investing a good deal of it as well on DEX for the evasion rate increase as well as the excellent damage boost. Capitalizing on just these 2 stats and ignoring both INT and STA may seem risky but the goal is to consider evasion as your defense increase while also increasing probabilities to deal extra damage.

mu origin 3 strange disturbance

Rangers can be an effective secondary class in both PvE and PvP content, especially at the hands of a skilled player who can utilize a good mix of skills for both offense and defense. For cooperative game modes, however, there are viable substitutes for the Ranger if what they bring to the table is exclusively damage contribution.

Considering everything we discussed in this class guide as well as our beginner’s guide, we cannot consider any single build as the absolute best considering the variety of content and challenges that are available in MU Origin 3. As such, do not fret much on how exactly you would allocate stats with a mindset that it needs to reach a perfect ratio for you to have an efficient character.

For the most part, what we consider is a focus on at least 2 of the 4 stats as we discussed in each subclass but those recommendations are open to flexible considerations given your choice of skills, ultimates, and talent prioritizations along with the plethora of other means on how you can strengthen your characters in the game.

Of course, there is also the factor of play style and content or contents you wish to specialize in based on your experience across the multitude game modes you have delved into. While MU Origins 3 provides players with 4 slots to create and enjoy 3 different character classes for now, you may want to keep a spare character slot available as the additional classes of Magic Gladiator and Summoner will soon become available to the global version of the game.

Similar to the overabundance of content and features it offers, MU Origin 3 is just as overly-loaded in terms of the ways and means you can strengthen and build your character. Although we did not dare go through all skills, ultimates, and potentials as well as made solid recommendations on which ones to choose for your secondary class choices, the idea of what to work around with as far as roles and stats go should open your mind to ideas on how to create your ultimate hero.

Builds and play styles are certainly unique for each individual and it will certainly be close to impossible to find 2 players with the exact same one in the whole virtual world of MU Origin 3. If you are one who are confident enough with how you built your character, or at the very least have a concrete idea of your work-in-progress, we very much welcome you sharing your tips and considerations in the comment area!
