He grabs her hand and opens a portal, a tear in space; the center seems disturbingly to pseudo-reflect a distorted version of Opalyn's own form, though maybe it would do the same for anyone else who looked at it.
If Opalyn is paying attention she can see how his own power is tearing through wards that were laid down upon this space, to prevent portaling like this if somebody much less powerful were to try it.

It's complicated, and sharp, and feels like it really would be a lot easier to build if you were aware of how magic interacted with magic and didn't just will all of it to jump into place on demand.
