Grace was pushing further ahead while the frost finch flew higher in to the sky. She had already started to channel the ice energy through her body and in to the rapier she had drawn. Since the frost finch seemed to be retreating, the boy with the soul stealing anemone ignored it. He told his anemone to focus on Grace.
The moment that Grace was close enough, three of the anemone's tentacles lashed out at her, however, she was nowhere near where they had attacked. The ice that she had her frost finch blow in the breeze and hit the anemone had landed on the tentacles. It was just enough to cause the tentacles to miss slightly.
The stiffness in the stingers and muscles was just enough so that the anemone was also lower. As it retracted its tentacles to try and whip out again, Grace was able to channel more ice energy through the rapier and strike out at the tidal turtle's limbs.
