Hello. I don't know if you just haven't gotten to it yet, or if it is an error, but the Changecaster, Herald of Tzeentch's Rites of the Herald has no description. Also, it seems like on the world map, the images of Cult Magister of Tzeentch, Sorcerer of Change, Sorcerer of Scheming, Changecaster, Herald of Tzeentch, and the Sorcerer of Magic are squished, small in comparison to the rest of the images.

The squished images is a product of them being a bit too large for the normal 1x1 sprite size. There's not much I can do about it without making the sprites extremely blurry instead.

You'll notice that the Nurgle heralds have the same issue. I've had a fix in mind for it for a while, but haven't gotten around to trying it yet.

Tested the fix, it did not work. Best I can probably do is make the canvas size of the idle sprites smaller, though that won’t work for the Heralds.

Treason of Tzeentch doesnt work. Never saw it to charm unit.

Last I checked, it uses MR easy negates, so the odds are very low. I’ll check to be sure, though.
