This seems pixelated and looks like a blown up cnp of the actual ward eye from the game.?

it's an old icon of mine.

I know these row of icons feel "blurry" and substandard... but from my experience icons don't have to be HD to fit the wc3 style and look good ingame, and these ones I will be reusing in my new map.

Could benefit from additional shading but useful nevertheless.
