Pedro simply stole a glance towards Arvedar, before he shifted his attention back and watched Sabrina familiarize herself with her transformation skill. He became excited as he thought what changes the second random creature transformation skill page would give to Mathew and Talia.
He still don't have a hundred percent assurance that using the transformation skill page for the second time would grant a level up on the first transformation skill generated, instead of generating another different transformation skill.
That said, Pedro can't help but feel ecstatic after knowing that Sabrina's transformation skill had leveled up. He could only hope that it would be the same case for Talia and Mathew, once they use the random creature transformation skill page for the second time.
