A strategy to counter "glamour"?

[PaoloZ]

Thanks Agrajag, just kidding about the more frequently used meaning of the word...
Will search for answers as you suggested

100% precision spells usually knock a unit out of glamour, try frozen heart.

Try thugs with eyes of the void. Or try that other artifact that dispels illusions.

I also like area effect damage spells, shimmering fields come to mind. Thos seem to work nicely.
