The pillars start to be successful in impeding Trixie's movement for a small amount of time, her bumping into a couple. But then again, part of Trixie's performances requires her to be a magician. As such, she uses the pillars to her advantage. She makes it so it seems as if she pops out from behind pillars randomly, as if she's teleporting.

Using that cover, she fires off a magic blast every now and then.
