[Suggestion] New Spell
I got a possible spell idea (not sure if there's anything like this already) but something that would cause a city to appear more defended than it is. For example name the spell intimidate and have it appear to double the combat rating of the town you cast it on so while it may seem heavily defended there are only a few units there.
You could do another spell which is the reverse called ambush where it would show enemies half the actual combat rating of a city so while it appears lightly defended it could catch an invader off guard. Would probably be more useful in multiplayer than against the AI. Thoughts?
