Choosing a Class
Each class has its pluses and minuses, therefore there is no 'perfect' class. Some classes can solo more easily, and others are more reliant on their party. Below is a simplified view of all of the classes, more detailed information will be added soon including equipment, skills, etc.
Gladiator
Survivability: Medium/Low
Damage: High
Pros: Generates large amounts of damage and doesn't die too easily.
Cons: Constant need of MP-recovery items and hard leveling.
About: A sword-wielding class. This class uses a skill called Berserk that triggers an all-out-attack at maximum attack speed. For this reason, Gladiators do not need AGI. Gladiators mostly focus on maximizing their damage output and surviving while taking aggression.
Paladin
Survivability: High
Damage: Medium
Pros: High HP is great for parties, and is the only warrior that can heal
Cons: Takes a long time for paladins to kill their enemies and leveling is often hard.
About: A class that has high amounts of HP that distracts the enemy with its provoke skill, so others may attack without being targeted. Also gives helpful party buffs.
The main tank of the game, paladin is a special sword-wielding class. This class usually travels in parties. Because of their high HP and Provoke skill, Paladins usually take the aggression of the enemy, while other party members attack. Paladins can also heal others when needed.
Assassin
Survivability: Low/Medium
Damage: High
Pros: High damage, great buffs
Cons: Low HP and MP, and equipment is generally expensive
About: A class that generates great damage with throwing weapons and has high evasion.
Assassins are masters of evasion, and level easily with a AGI/CRT build until they unlock the skill Backstab. After getting Backstab, assassins unlock their full potential. A large amount of assassins reset their stats and use a throwing weapon to maximize damage after Lv140. Leveling with a Backstab build is hard, so be warned. Like snipers, assassins generate huge amounts of damage, but can not survive easily.
Sniper
Survivability: Low
Damage: High
Pros: Causes a sufficient amount of damage, great buffs
Cons: Low HP and MP, dies easily
About: A class that deals sufficient amounts of damage with bows, with a high probability of evading their enemies
The "archer", sniper is a bow-based class, focusing on long-range attacks. A sniper usually has low HP, so their main agenda is to kill their enemy before it reaches them. A single large hit from an enemy can easily kill a sniper, making this class lean on the dependent side. There are two types of sniper builds, arrow rain (AR) and auto attack. Arrow rain snipers will spam a skill named "Arrow Rain" that causes multiple hits at once. Auto attack snipers have an build based on using little to no skills. Snipers may also add VIT to their build to boost their HP in later levels.
Monk
Survivability: Medium
Damage: High, when at higher levels
Pros: High physical damage makes this a great solo class.
Cons: Can die quickly if the monk does not evade enough attacks and/or wear sufficient HP gear.
About: A high physical attack class that uses evasion as their defense.
Monk is a soloing class that deals huge amounts of damage due to their quick critical attacks. Monks will get the highest amount of damage by using claws. Low level monks will have somewhat low attacks until they get to higher levels, specifically level 180, when they can get a skill called Geo Breaker. They tend to be more powerful than ninjas and more supportive in parties.
Bishop
Survivability: Medium
Damage: Low
Pros: The ability to heal large amounts of HP and cast supportive spells make bishops extremely popular in parties.
Cons: Bishops are more of a party class, and aren't good for soloing mobs in general
About: One of the most sought out players for parties, bishops are advanced healers that use supportive skills.
Bishops, like paladins, are supportive members in parties. Bishops can heal the largest amount of HP in the game. They also have skills that can resurrect party members, restore their HP and MP, reduce damage received, etc. Bishops can level easily once they get the skill Nemesis at Lv180.
High Wizard
Survivability: Varies
Damage: High
Pros: High amounts of magical damage and skills to recover HP and MP make this a great class for soloing.
Cons: More damage-based builds will be vulnerable to physical attacks, some skills have a long skill delay or casting speed.
About: A class that casts magic elemental spells.
High wizards kill monsters with their elemental spells, easily breaking through strong boss barriers. They also get an AoE skill very early in the game, which makes leveling a breeze. They are popular in parties, but spamming spells will often lead to aggression, which can lead to a high wizard dying easily. High wizards are vulnerable to physical attacks, but overall a good soloing class.
Enchanter
Survivability: Medium/High
Damage: Medium/High
Pros: Quick attacks and autoskills can generate lots of damage.
Cons: Equipment and crystas tend to be very expensive, and enchanters die easily until level 160.
About: A magic-based class that quickly casts magical spells and relies on stoneskin to resist damage.
Enchanter is a magic-based build that usually uses magic swords to generate high amounts of damage. They will also use a skill called Stone Skin to resist damage. Enchanters have the option to focus on melee-based or magic attacks. Enchanters also have a counterattack skill that some plan their build around to optimize damage.
Ninja
Survivability: Varies
Damage: High
Pros: A ninja's Dance of Clones can cause high amounts of damage
Cons: Status ailments (poison, stun, paralysis, etc.) will easily kill ninjas. Constant need of MP-recovering items.
About: Ninja is a level 100 class that usually tries to keep their HP low to improve their damage using Dance of Clones.
Ninjas are one of the most popular classes in the game because of their soloing abilities. A ninja has 10 lives, or 9 clones of his/herself. Each time a ninja gets hit by an attack when he/she has a clone, they will not receive damage, but they will lose a clone. Constantly regenerating clones and making sure to have plenty of antidotes/vaccines/eye drops, etc. is what one should expect from this class. There are many types of ninjas (magic, bow, claw), which makes this a go-to class for many people wanting to try a unique but effective build.
Samurai
Survivability: Varies
Damage: Very High
Pros: Samurais are a high-damage and survivable class if build correctly
Cons: Weapons can degrade, constant need of MP, leveling is hard before level 160
About: Samurai is a sword-wielding damage per second class
Samurai is a high damage per second class, that can have lots of DEF, MDEF, and evasion with the right build and equipment. Samurais cause huge amounts of damage, but at the minimum attack speed. Samurais use special swords, like Paladins to be tanks in parties. Most of the skills for this class focus on increasing damage. Samurai is a hard class to level, so it's recommended to wait to switch to this class at higher levels. Samurais can not increase their attack speed.
Minstrel
Survivability: Medium/Low
Damage: Low to Medium/High
Pros: Minstrels have helpful buffs
Cons: Depending on the build, Minstrels can have either a harder time with surviving or damage, and are not popular in parties.
About: Minstrels have flexible builds, but most of them buff their party members
Minstrel is a rare special class. Minstrels usually buff parties using their skills, though others tend to lean more towards physical attacking. Contrary to popular belief, minstrels can not revive dead party members. With a hard time soloing and not much luck finding parties, most people will switch or delete their minstrel characters.
Adventurer
Believe it or not, some people never change their class, even though they know they can. In the Japanese version of Iruna, adventurers get special equipment once they reach level 200. So far, the only equipment that we know of is Adventurer Clothes and Adventurer Knife. Most people find the idea of a high-level adventurer to be impractical, but it's actually not too bad of an idea. If you ever decide you don't want to be an adventurer, you can always pick any class you'd like, you can even reset your skills using and item from the Item Shop. Adventurers usually use the skills that can be synthesized (such as vampire blow) and have other people help level them.
