Each Hero belongs to one of the three classes.
The Hero class is determined by the three basic skills (displayed in the upper part of the Hero Skills window) and the Specialties.

There are five branches of Skills (Specialties) in each class. One branch is determined by the Hero primary Speciality, and two more branches for studying can be chosen by a player.
Each branch contains 6 Skills.
Some Skills are passive and some – give spells.

Three basic Skills:
Hero Speed - passive skill
Catapult - spell
Mana Regeneration – passive skill
