Frost was presented with five options each with their own strengths and far more varied than with the frost goblins. Unfortunately, there wasn't an option for an ice dwarf, looks like he'd need to evolve these three once again in order to unlock it, or he could wait until his strength and knowledge grew to the point that he'd get them naturally, but he wasn't one to be passive. These three frost dwarves would be placed on the front lines, actively trying to have them reach max level once again. They'd still be E-rank so reaching max level again wouldn't be too hard.
