Indeed. Mana Shield to become useful against stronger opponents it would need to be a much, much higher level and Sasha would need to increase her Focus and INT to make the Skill stronger as well. After that, Sasha decided to spend the last of her morning investigating the Familiar Gem, which according to the Observe Data (by this point, going to just have assumed that Sasha and Silas got it after some point, ill put it on the CS's shortly), contained something called a Soul Familiar. This Familiar was born from a piece of the summoner's spirit and grew as their abilities grew. 

At first nothing happened, and it didn't seem like anything would happen. Suddenly though the gem began to glow brightly, and she would feel it making a link with her very soul and spirit. The gem continued to shine brightly, as it slowly began to vanish from her hand and go inside of her very being. After that, like a beating heart, it would slowly begin to be filled with life as it began to shape and form deep within her spirit. She felt as though she could somewhat enhance this process if she focused hard enough, the following window appearing before her.

This window probably felt like the molding the Familiar with her will part as well, as she was literally deciding her familiar's abilities.
