Rocky had never thought of getting a soul familiar before.
The tower's historic lore suggested that having a strong familiar greatly increased one's chances of becoming a successful climber, which was why, no climber ever made the choice of choosing a familiar haphazardly.
Rocky too wanted to someday choose a strong soul familiar like the nine tailed fox, or a mighty dragon, however, he had never thought about it too seriously.
A transforming ice bunny, while not a bad species to form a soul-contract with, was not the first choice of most climbers either as except for their insanely high attack power, their defense was considerably weaker when compared to other species.
They were like the phoenix, however, weaker as while the phoenix held superior control over fire, one of the basic elements, the transforming ice bunny had complete control over ice which was a modified element derived from the basic element of water.
