yes!

you think about it for a small moment before you decide to evolve. you say "evolve",when a blue, mechanical, half-transparent screen, just like the status screen, appear before your eyes.

monster evolution:
Minotaur chief- leader of the minotaurs, his appearance can change the battlefield in an instant/perks: lord of the Minutaurs- gives buff to all other minotaurs on the same side as you a buff to all stats equal to half your stats. apply also to your children and submitted subordinates/upgrade trait-strong. if you have the "strong" core, it will be upgraded.
Minotaur mage-few minotaurs are able to abandon their ways and become mages. fewer do it./perks: minotaur mage- this will earn you respect from all minotaurs and monsters. obviously it will let you use magic/ upgrade trait-arcane. if you have the "arcane" core, it will be upgraded.

class upgrade:
assassin:
shadow assassin- a class specialized in stealth and lethal hits.
manslayer- a class specialized in the killing aspect of the assassin.

barbarian:
berserker- you have fallen to your rage and became an undying berserker.
warrior- you learned to control your rage and so became a warrior.
