Domain expantion-Death Marble

This spell is one of four spells that are at the pinnacle of entrapment spells. Upon using the spell you must select one target within 60ft that you can see and that isn't obscured by 3/4th or full cover and has more than half their hit points. When you have selected the target they must make a Dex saving throw of 17 if they succeed on the roll you do not expend your spell slot but gain 2 levels of exhaustion. If the target fails you and the target are encased within a endless dessert and are unable to cast spells and lose all equipment you had from the outside world. Once inside the domain the field is filled with short swords in witch whoever is still standing is the victor and the domain is released and all spell casting and equipment is then returned. The domain can be dispelled from the outside using either magical means or forced entry by a monk.
