With one last look around and up (you never knew if someone was at a window) she used the salt to create a basis for her circle. Given the danger of what they were about to attempt, she didn't just stop there as she might have for lesser spell working. Next she gathered dirt from a crack in the alley and mixed it into the salt, following that up with a cut to her hand to drip spots of blood within the circle to make the points of a star shape. The points were accented by bits of trash she found and then lit on fire with a lighter from her pocket.
Wanda straightened then, in the midst of her protective shapes and absently ran a glowing fingernail along the cut in her hand to heal it. She glanced at Daimon and asked, hopefully, "Holy water?" He'd conjured the salt after all, and she wouldn't mind another element to strengthen the circle. The "holy" bit was a half joke- but really a little extra added superstition couldn't hurt.
