Clean out and fortify dead

This cantrip cleans out any unwanted material(like the intestines, vessels, etc.) from the body of a dead creature of any size. This cantrip also strengthens the defense of a dead creature raised by spells like animate dead, by boosting their ac by half of the caster's total level at the time of reanimation(rounded up) or casting of the spell. (The caster is the center of the 40 ft. radius.)
At 5th level, you can clean out and fortify three corpses, and the radius increases by 20 ft.
At 11th level, you can clean out and fortify five corpses, and the radius increases by 20 ft. 
At 15th level, you can clean out and fortify seven corpses, and the radius increases by 20 ft. 
At 20th level, you can clean out and fortify nine corpses, and the radius increases by 20 ft.
