From each sub-class, you can take three passive skills for the main profession of the game character. With a good choice, this can decently enhance it. The most difficult is pumping the sub-class to level 75, since all three skills will be available to you on it: the first is available at level 60, the second at level 70, and the third, respectively, at level 75.
Necessary
a character with a sub-class pumped to level 75
Instructions
Step 1
First you need to complete the More Than Meets the Eye quest on the sub-class. The quest is taken at Hardin's Academy (Academy of Hardin) from the NPC Hardin (Hardin). He, in addition to the ability to learn skills from the sub-class, will allow you to further study all sorts of useful transformations. The quest is available already from level 50, so you can safely go through it in the process of pumping your character at a time convenient for you. The quest itself is quite simple: you need to move from one NPC to another using the directional arrows and knock out the items they ordered from the monsters: Ectoplasm (ectoplasm) - 35 pcs. and Mordeo Crystals - 5 pcs. The quest ends at the same NPC with which it began: Hardin (Hardin). He should give you a transformation book.
Step 2
Next, fly to the Ivory Tower (Ivory Tower) on the second floor and there, at the Transformation Wizard Avant-Garde NPC, teach transformation. Now you can transform into Beast Onyx (Onyx Beast) and start learning skills from the sub-class.
Step 3
Next, you need to come to the guild of your race and from the main NPC (in all guilds he stands separately, at the head of two rows of his subordinates) take the specification books. Such guilds are located in the Ivory Tower itself and in all major cities. It is imperative to come to the guild on a sub-class, go to learn skills too. This is a prerequisite for achieving your goal.
Step 4
With the books, you must return to the Ivory Tower (Tower of ivory) and again approach the NPC Transformation Wizard Avant-Garde and learn the necessary skills from him. Think carefully about what skills you need. Do not chase tempting abilities like "temporary indestructibility", as they work extremely rarely - the chance is about 3%, but in fact, you can play for years and not see the activation of the skill.
