There are three main classes and one secret class in Idleon, but where it becomes complicated is when you need to choose subclasses and the choices multiply.
This article will showcase how to select a new subclass to start with and also how to get the subsequent classes later in World 2, World 4 and World 6.
Alongside the class selection quests, we will showcase all the possible classes and how many of which class you should be getting.
Don’t get intimidated by the amount of choices as you can’t go horribly wrong, as there are ways to change your subclasses with gems and you can always reset your talent points with certain potions.
The only thing you must worry about is to have a maximum of two of the same base classes, as those can’t be changed later on.
Which classes to choose first?
You can make up to 12 characters in Idleon, but each of them starts off as the Beginner class.
Once you reach level 10, you can choose your first class between a Warrior, Archer and a Mage.
In Idleon it is crucial to have at least two of each base class eventually, as they all have two sub-classes and their own unique skills and proficiencies in different areas.
However, there are only the three starter classes mentioned above, so your characters should be evenly distributed among all three.
There is also a special class, the Journeyman which requires a secret questline to obtain, but you should only make one of this class and only after you reach World 3.
The tables show what professions each class specialize in, but any class can work on any profession, some classes just have unique talents to boost their mentioned profession.
Class specific profession note!
Technically none of the professions are class specific, some classes just have boosts for specific professions.
Eventually you should get all skills on all characters to level 100 to get stat boosts from the best tools that require level 100 to equip.
However that is a very very late-game goal when you have nothing better to do, so don’t worry about it at this point.
As a good rule of thumb, once you hit level 100+ on all skills with your Journeyman, then you can start leveling all your other characters to 100 in each skill as well.
Eventually you will level all characters professions to multiple hundreds as long as your Journeyman always has the highest profession levels!
In general you should pick a Warrior, Archer and a Mage as your first three characters, then the same three again as your next three characters.
A warrior is probably the easiest class to start with for fast mob kills and mining early on, while an an archer is important to get your Smithing level up as fast as possible to craft better equipment.
Mages and their chopping skill is not as crucial, so this should be your third class. They become more important in World 2 with their Alchemy boosts and once you get to your second class advancement, a Bubonic Conjurer is great for grinding kills with its huge AoE gas attacks.
Here is a general path you can follow safely to have all the needed professions and classes for optimal progression through the entirety of Idleon:
The main key is to not have more than 2 of each “third subclass”! So max. 2x Divine Knight, 2x Elemental Sorcerer etc. And remember, only 1 Journeyman! The game has also added a subclass swap token into the Gem shop so you can change your classes if you make mistake.
You will learn more about each class and skill as you keep playing the game, so as long as you have the selected classes, you will eventually find out what each class and subclass excels at and which do not.
The very best part about Idleon is experimenting and finding out fun builds and combinations yourself, so don’t get too stuck up on following guides like a robot, remember to have fun too!
Activating the first subclass
The level requirement for getting your first class advancement or so called subclass is level 10.
On top of that you must also reach the third map in World 1, called Valley of the Beans.
That map contains an NPC called Promotheus who is responsible for promoting a level 10 or above beginner class to any of the three base classes, Warrior, Archer or Mage.
Once you click on Promotheus a few times, you will be prompted to select your new class. Make sure to pick exactly the one you want, as this choice is permanent (unless you purchase a subclass swap token from the Gem Shop).
Now you can set your new class skill points and continue playing as normal until you reach World 2 and are ready for the next class advancement.
Getting the second subclass in World 2
Once you’ve beaten Amarok in World 1 and have tipped your toes in the confusing world of Alchemy, you might be wondering how to get to your next, arguably the most important, class advancement.
The second subclasses specialize in either World 2 or World 3 skills, so make sure to select all the World 2 related classes as your first promotions.
Each base class has two options to choose from during the second subclass selection, detailed in the table below.
The second subclass also has its own NPC, Speccius, you must talk to within World 2, located once again in the third map, Dessert Dunes.
However, different from World 1, this time you must complete a simple quest before you can select your second class advancement.
In order to select your second class, you must bring the following items to Speccius:
| Image | Name | Amount Needed | Main Source |
|---|---|---|---|
 | Kebab Sticks (Food) | 130 | World 2 Shop (Total cost:  2  49  6) |
 | Crabby Cakey (Monster Drop) | 150 |  Crabcake |
These will not take too long to acquire, as long as you can afford to buy the Kebabs from the town shop.
The good thing about this quest is that the items are not consumed upon completion, so you can put them in your storage chest and use the same kebabs and cakes to complete the quest for all your characters.
Once you’ve given the items to Speccius by talking to him a few times, you will be prompted to select your secondary class.
Remember to make the World 2 related classes first, so Barbarian, Bowman and Shaman, so you can level those skills up while you progress towards World 3.
It is good to note that the third subclass comes up in World 4, which will take a very long time to reach from World 2, so don’t worry about it too much.
Once you have created at least one copy of each unique secondary class, it might be a good time to create the Journeyman class as your next character, if you haven’t already.
Unlock the third subclass in World 4
If you have reached World 4, you sure need no more introductions to how things work, you just want to find out what classes are available and where to choose them from.
As before, you get unique class choices depending on your second class, but this time you only get one option, so there is no choosing this time.
As you may notice from the table, half of the new classes specialize in World 4 skills while the rest are meant for World 5 skills, which are not out at the time of this writing.
You are still safe to upgrade all your characters already, as the classes will not change, only more skills will be added to them in later updates.
In order to unlock the third subclass, you must reach the fourth map in World 4, called Outskirts of Fallstar Isle.
There you will find an NPC named Eliteus who will provide you with the third class advancement.
You will need to first kill a few enemies which spawn after you talk to him the first time, but this should be extremely easy and take only a few seconds.
Then, same as before, you will be prompted to select a new class once you talk to Eliteus again.
Unlocking the fourth subclass in World 6
At the time of writing, only a single fourth class advancement has been added to the game, which is the Death Bringer class for Blood Berserker.
If you have two Blood Berserkers, feel free to make two Death Bringers, as they can surely be changed later if more mastery classes are added in future updates.
As you might notice, World 5 has no class NPC’s, so you must advance all the way to World 6 for this and find the Masterius at the Troll Playground map.
He will provide you with a quest to kill 92 different mobs, after which you will unlock your new class.
This simply means you have to go through all maps from World 1 to World 6 killing unique monsters.
Thankfully there is a way to speed this up, which is by going to the various Colosseums in each world which contain most of the different mobs of each world (and even the Colosseum chests count as unique mobs).
You can also defeat World Bosses and Crystal mobs, as they also count towards the counter.
Then simply go talk to Masterius again to unlock your new class!
