Vortess Nebulae is a powerful spell, capable of creating a force field which can deflect lasers, rays or beams. After its initial use, the caster may reform or deform the shield at any time using the aura it initially formed over their hands. The field can be created to protect anything or anyone, not just the caster.
Charmcaster refers to this as an invisible force field spell though it was shown as a visible blue or pink force field.
In Evil's Encore, 11 year-old Gwen used the spell again to paralyze a moving fan.
