Su was not shy when it came to how she wanted to train with them. She simply put herself in the position that would be most affected by the cold and frost; right in front of Midnight. Ar first, Walker wanted to warn her because he could see her shivering but when he realized she was copying him and trying to meditate he had a better feeling. Su was trying to understand why she was cold and the effects the elemental mana had on her body so that she could develop a mental resistance first.
Every failed breath attack from Midnight sent flurries of snow and chilling air right on to Su. Each time Su would shudder with the cold that sapped away her heat and forced her joints to become stiff. Her armor was a good defense against the breath attack since it was technically a magical elemental attack, but the cold air was another thing. It was pushing through the cracks in her armor and hitting her real body.
