She's been healing people left and right from the start, she ran out of energy. She wasn't just healing Desir a few times. It's explained better in the novel than just the few images here, but Desir's body was literally being ripped apart and she had to repeatedly and fully heal his whole body in the span of a second when she was already running low on power.
She was supposed to heal Desir from the start because his body wasn't going to be able to handle the magic/mana load but then acts surprised when he starts to explode and acts like "oh what do we do?!" and next she's suppose to be this ultra elite heater and she couldn't last long enough for him to cast the spell??? Am I the only one disappointed with her???
