How to against invisible units in AOE?

[parousie]

My civ is Grigori, it means I can't reserch Honor for building light of lugus.to reveal the invisible units. .
There is a promotion called perfect sight. It allows the unit to see the stealth in FF, but it is replaced with +2 perception in AOE.
Is there any other way to reveal shadow for Grigori?

Hi,
we merged perception and the stealth system a few versions ago.

Now, to see invisible units, you need to increase your perception. There are different degrees of stealth requiring more an more perception to unveil.
