This spell combines several elements to create a powerful protection from
scrying and direct observation. When casting the spell, you dictate what will and will not be observed in the spell's
area. The illusion created must be stated in general terms. Once the
conditions are set, they cannot be changed.
Direct observation may allow a save (as per a normal illusion), if there is cause to disbelieve what is seen. Even entering the
area does not cancel the illusion or necessarily allow a save, assuming that hidden beings take care to stay out of the way of those affected by the illusion.
