Character skills are very important in Mortal Online, as it is your skills and not any "character level" that define what you can and cannot do in the game. The skill system itself is very dynamic, meaning attributes and skills are dependent on each other, and that training one of them also improves the other. It also gives you the opportunity to fully customize your character. Unfortunately, this system may seem a bit confusing at first, especially when reading about it, but let’s look at each piece of the system one at a time:
There are two main types of skills in Mortal Online: Primary and Secondary Skills.
The Primary Skills are the most basic skills in the game and also the foundation for the rest of the skill tree. All characters have these skills from start, but it’s up to you which of them to train. The different Primary Skills “unlock” different Secondary Skills in the skill tree; for instance you will need to train the Primary Skill “Acrobatics” to a certain value to be able to learn the Secondary Skill “Climbing”. Like the Primary Attributes the Primary Skills have a common cap, meaning you can never fully train each and every Primary Skill. It’s up to you to find the perfect balance for your character, as you can train and untrain these skills how many times you like.
The Secondary Skills are the bulk of the skill tree. They are of a vast number of skills that are connected to each other in a very complex network. Secondary Skills have to be discovered and learned in the game by books, tutoring and/or to a lesser extent by other means like magic or achievements. The prerequisite of a Secondary Skill may be another Secondary Skill, a Primary Skill, any Attribute or any combination thereof. For example, learning the Secondary Skill “Advanced Poison Making” may require you to have the Secondary Skills “Beast Lore” which in turn is based on “Zoology”, as well as “Poison Making” that is based on “Basic Herbalism” that is based on “Botany” and so on.
The major difference from the Primary Skills is that Secondary skills don’t have a common cap. You can learn any number of Secondary Skills you like, but the skills you can learn are restricted by your Attributes and Primary Skills. The restrictions also mean that if you “untrain” a Primary Skill or Attribute that is a prerequisite for one of your Secondary Skills, you won’t be able to use that Secondary Skill any more. However, should the prerequisites once again be met it can be used as before (so you don’t have to train it over again). In short, you can explore any area of the skill tree without the fear of getting stuck, as you can always “leave” and “come back to” your Secondary Skills that are already trained with the help of a little time.
Every skill in Mortal Online is either an Action Skill or a Learning Skill. Some of the Secondary Skills are also tagged as Deva Skills (or “Account/World Skills”).
Action Skills An Action Skill is trained by using it in the game. By using your Arming Sword you train the skill “Arming Sword” (and also, to a lesser extent, the skills and attributes that have a connection to it like “1H Swords”, “Light Weapons”, “Strength” and “Dexterity”).
A Learning Skill is passively trained by “reading a book” or “studying it mentally”. This takes time, and the more difficult the skill, the more time it takes. You can only train one Learning Skill at a time, but during that time you can of course train any number of Action Skills as their training is dependent on your actions in the game. Although most Learning Skills are passively trained, some of them will also benefit from certain “actions” in the game, i.e. the Learning Skill “Zoology” might increase each time you discover a new creature. (In this case, the skill don’t have to be the one “currently studied” to increase.)
Some of the Secondary Skills are tagged as Deva Skills. (The Deva is your “shared soul” that connects all your characters on your account.) When a Deva Skill is trained, all your characters will benefit from that training. As all Secondary Skills have prerequisites it does not necessarily mean they can use the skill, but it means it will be there, trained to the same level as for the other characters, and once the prerequisites are met the skill will be active and ready to use (see Secondary Skills).
