Improvised Plan.
Svetlana got close to Emily first and knocked her hammer out of her hand taking advantage of the fact that Emily's grip on the hammer had lessened after she got slammed away by the wave of the explosion resulting from the destruction of the Astral Construct.
With the hammer out of Emily's hand and her ability to react hindered, the blue-eyed witch proceeded to summon her cosmic Armament for the first time so far.
Svetlana's Cosmic Armament was a spear with a very garnished headpiece that was meant to be a symbol of status and power just as it was meant to be a tool for violence.
She stabbed at Emily with the Spear but Emily initiated her failsafe to warp reality and move into safety and once she did, she was still in range of Svetlana to grab her leg and whip her aside.
