Ethereal Purge

This spell allows a cleric to pull an ethereal creature into the prime material plane and bind it within the bound of a magical circle.

Any Ethereal creature within the Radius must make a wisdom saving throw or pulled into the Prime Material Plane and bound within the radius of the magical circle. if an ethereal creature enters or ends its turn within the magical circle it must make also make a wisdom saving throw or be pulled  into the Prime Material Plane and bound within the radius of the magical circle. this also effects creatures that can temporarily become ethereal such as the Phase Spider or a magic user under the effect of Etherealness or similar effects that transport a creature to the ethereal plane However this only works if the saving throw would be prompt while the creature is ethereal. 

This spell only works while on the prime material plane.
