This encases the target in a transparent sphere with DR 20 and HP 60. Characters can still move around by walking inside the bubble (somewhat like a giant hamster ball), unless it gets stuck somewhere.

The sphere is porous, so fluids such as air or water can move through it, but solid objects cannot.
