Quote:It would be interesting to look at the bonuses/privileges offered.

In a first step, this would be the possibility to choose from the new level of secondary skills only the class can access.
For example:

Grandmaster Leadership
Grandmaster Leadership increases your hero's troops' morale by 3.
Also, creatures who had moral in combat deal bonus damage with the next attack.

Master Archery
Master Archery increases the damage done by range attacking creatures by 65% and eliminates obstacle penalty.

Grandmaster First Aid
Grandmaster First Aid gives control of the first aid tent to the hero, healing 300 points of damage to the first unit of the selected stack.
Also increases the life of all units by 15% and the first aid tent revives more dead troops after combat.

Master Mysticism
Master Mysticism allows your hero to regenerate 15 spell points per day.
Also, you have a small chance that damage spells will deal more damage in battle.


and so on...

The second layer of bonuses can be acquired when reaching the next level of that class.
E.g for Mages: Spells deal more damage when cast from a full mana orb.
Warriors: First strike in combat deals bonus damage
Adventurer: Resists the first spell cast by enemies in combat

but these extra privileges are just ideas and not yet implemented.

How do you imagine your privileges for the different classes? I think they are necessary to make the skill system more diverse and interesting.
