During this phase of the battle, she will teleport in different places around the area, which she will unleash one of the following attacks: she'll either release orbs of light that spread throughout the screen, unleash four bolts of lightning in different directions, or fill most of the screen with many lightning bolts, leaving a few safe spots for the player to hide in. Both of the last two of those three following attacks involve the Blitzstrahl.
