Darla's mouth gaped open, looking at the class stone in her hand. Then she looked up at Red. Her head was getting fuzzy, and I could not believe what he had in her hand.
Just like a core, a class stone was something the adventurer or mercenary could obtain from the dungeon. That was her limited information on how to obtain the class, but she was well aware of the class rarity.
It started with Common Class like the one she had. Then there was Guard, Warrior, Archer, Shield Bearer, and more. Those were Common Class.
Then there was an Uncommon Class. She had limited information, but she encountered a few of the adventurers with Uncommon Class. Her friend had a Hunter Class, which was Uncommon Class. Her friend's adventurers also mostly had Uncommon Class, with their leader being a Rare Class holder.
