Catchphase

Worlds overlap as you temporarily merge the ethereal and material planes in a 100-foot cube originating from you. For the duration, creatures in in the area are considered to be on both planes. Creatures on either plane can see and interact with creatures in the area as if they were on the same plane, and all structures and objects in the area that would appear in the same space harmlessly merge and overlap. Any spell or effect that would cause a creature or object to shift between the material and ethereal planes fails, without consuming spell slots or feature uses.

If this merging would cause a creature to occupy the space of another creature or object, they are harmlessly shunted to the nearest unoccupied space.

When the spell ends, all creatures, structures, and objects return to the plane they occupied before the spell was cast.
