Dr. Falren's Field Hospital

With most cities being ill-equipped to deal with mass disaster, disease or catastrophe, you alleviate a portion of the workload by conjuring a field hospital. This field hospital can be any size and shape but cannot exceed a size of 75 cubes, each cube being 10 feet on each side. When conjured, the field hospital contains 100 near-transparent nurses that act on your commands, 50 beds that can hold medium sized or smaller creatures, multiple sets of medical tools and supplies and a stock of potions and remedies that can cure up to 200 creatures of basic poisons and diseases. 

The area within the field hospital is confined by a tent like cover that spans over the top and has supports coming from the ground. The sides of the field hospital can be open or closed, you choose when you first set the spell. You can change this at any point during the duration as many times as you want and the temperature within is always comfortable. The area of the spell is always clean and tidy. If an obstruction is made, the nurses make it a priority to clear it and any simple messes that are made are magically cleaned by the spell. Any tools created by this spell are also magically cleaned once you're done using them. You can designate up to 10 other creatures to issue commands to the nurses and they will follow their orders but will always prioritize your commands. The area within is always bright light and the surrounding area is lit by 20 feet of dim light.

This spell and any creatures within its area cannot be targeted by divination spells and sensors created by divination spells cannot enter the area or pass through it. Once a creature exits the area, they lose this benefit until they enter it again. Nothing is able to teleport in or out of the area. There is a 250 foot radius circle starting from the center of the spell. Along the edge of this radius is a modified Alarm spell. You can designate creatures and creature types that will and will not make the Alarm trigger. Creatures you choose within this radius know when the trigger goes off mentally, and an auditory sound plays within the field hospital. When an Alarm goes off, you know exactly what type of creature it is, how many there are, and which direction they triggered it from. When the Alarm spell is triggered, it does not disappear and lasts for the duration of this spell.
