[HoMM3 on-line Tournaments] Arena "Will and Reason"

invisible (blue, Barbarian, Crag Hack) def Kamikaze (red, Tower, Nila).
The opponent was puzzled that he wanted to blind the bears in the first round, but it was written that it wouldn't work :smile32:. Bug or not, who knows, but it wouldn't have helped anyway.

Confirmed...blindness probably wouldn't have saved him, but still. After the game, I loaded the last autosave and attacked Nela with Crag, and the blindness worked for a round or two!

I looked at the save and found the following.
Blindness only starts to affect Crag Hack's army when he removes the "Sign of Courage" artifact (adds 1 to morale).

Maybe this is an unknown bug, or maybe it's a feature not mentioned in the manuals (programmers have a sense of humor and are sometimes capable of such things), but the situation is clear.

Added: by changing the heroes' races, I tested "Sign of Courage" on a completely different map.
Blindness still doesn't work.

Until the circumstances are clarified, to avoid controversial situations, I recommend not buying this artifact at all. Fortunately, there is a replacement for it.

Added: and why didn't I read FizMig right away? It turns out that everything has been known for a long time. I quote:

"Sign of Courage". Increases Morale by 1. (In addition to increasing morale, it gives all your troops immunity to mind control spells, both positive and negative - this is most likely a bug in the game, because the help file doesn't say anything about it).

Therefore, in the current arena round, we prohibit the use of the "Sign of Courage" artifact in battles.
