Name: Masfar
Biography: The first gargoyle was created by the great mage Masfar. He tried to hold the soul of his deceased daughter, but he only managed to create an illusion of life...
Specialization: ?Sculptor?
Here are a few ideas: either +1 to defense and attack for every 2 levels, or at level 5, gargoyles get +2% initiative, at level 10 +1 skill, at level 20 +3 defense, and at level 40 +1 to maximum and minimum damage. In both cases, the hero starts with 3 squads of gargoyles.
By the way, is it possible to create a special ability based on the skill of gathering troops? To give an additional bonus to the creatures that the hero has a special ability for? Of course, such heroes will be useless as main characters, but they can be quite suitable as additional characters.
