Donald Trump's Quirky City

You and up to 9 other creatures within ranged are transported to any city. You must make a charisma check that is DC 5 if the city is within 50 miles of you, DC 10 if it is within 1,000 miles of you, DC 15 if it is further than 1,000 miles and on the same world, DC 20 if it is on another plane of existence, and DC 25 if it is in a different world on the material plane. A creature who fails this save is instantly transported into a luxury suite in Trump Tower, New York. Their stay is paid for for one week. They may only return to the campaign setting if they visit every location bearing the Trump name, after which they are magically transported back to the origin of the spell as if no time had passed. Creatures who succeed are transported to the city, as is a manifestation of Donald Trump. This manifestation is not the Donald Trump from our reality, but a new Donald Trump that was born in the setting that the city is in and has never left that setting within his lifetime. He looks, sounds, and acts just like the real Donald Trump, but he wears clothes that would be considered noble in the setting of the city. His past life is as similar to his real life as possible within the setting of the city, and he has experienced some version of Donald Trump's life up until January 1, 2015. He uses the commoner stat block, with the exception that he is immune to all damage dealt by anyone affected by the spell, cannot be held in any magical prison, (such as a demiplane) and cannot be manipulated using magic. Donald Trump's main goal is to control the city that the creatures affected by this spell teleported to, and the creatures affected by this spell are obligated to help him gain control. The DM selects an amount of time that is no less than 3 months and no more than 3 years. If Donald Trump does not control the city by the end of that time period, creatures affected by this spell teleport back to the origin of the spells casting, and take 6d8 force damage that cannot be avoided, and cannot be healed until 1d4 days pass. If any creature affected by this spell actively and conscientiously takes action against Donald Trump, they return to the origin of the spells casting and take 20d12 force damage that cannot be avoided. There can only be one Donald Trump per world or per plane other than the material plane. If a player attempts to cast this spell when they still need to help Donald Trump gain control of a city, the spell fails. If a player casts this spell after Donald Trump has taken control of one city in the same world, Donald Trump will use the influence he has as leader of one city to gain control of the next. If two Donald Trumps from different worlds or planes meet, they merge into one entity that can freely travel between those worlds or planes.
