Artoria:
Step 1: Acquire Ruxen and Taura's powers.
Step 2: Lauch self fast down towards the plasma.
Step 3: Create glacier to block plasma.
Step 4: Store up a little extra ice power upon foot, while transforming mostly into Taura with "heavy" powers, as I was told she had.
Step 5: Glorious impact explosion. Explode current glacier, but create ice spike in its place to ride through explosion.
Step 6: Ride ice spike towards Eos. Laugh maniacally.
