Does the Nystul's Magic Aura spell mask the auras of spells cast after it?
Suppose I cast a transmutation spell on an object, then cast Nystul's Magic Aura to make the object appear non-magical, and finally I cast an illusion spell on the object. Assume both the transmutation spell and the illusion spell create persistent magical effects that can normally be seen using Detect Magic. If someone looks at this object using Detect Magic, what aura(s) will they see, if any?
