Detect Glamour

[AreaOfEffect]

The cheapest way to see the entire army remotely is to cast call of the winds. It's only 5 air gems, takes a air 2 mage to cast, and gives you a detailed makeup of the enemies defending army, even the glamored part of it. The alternative is to attack with a retreating scout.

The unfortunate thing is that you can't see their army without initiating an attack. Therefore there is no way to gauge a glamored nation's force before you start a war. The information may still be inaccurate if the glamored units are stealthing in their own territory, which easily happens when they aren't at war with you. You might get away with saying that the scout was suppose to stealth rather then move, but casting call of the winds would certainly be seen as an act of war.

Call of the Winds and other remote spells do not work against glamoured units because of the fact that the default behavior for stealthy units is Hide. And those are the units that you REALLY don't want to be surprised by.

When all else fails, diplomacy might work - explain to the target nation your problem and ask for either an NAP or war. (Attack with scout if NAP is not agreed).
