HoMM3 HD bug reports.

I recommend reading the artifact's function in the manual. All questions about "bugs" will disappear.

Does the Heroes community always treat people like idiots? I read everything I could about this artifact before registering on this forum. No, the artifact was in the slot; moreover, it was key to defeating the opponent. The opponent did not have a magic resistance skill. The save was lost as soon as the battle ended. In principle, the only thing found about the artifact's function is the excerpt mentioned above: "If its target is an enemy, it affects all enemies and only those of its own troops that it affects without the Sphere.
If the artifact's wearer casts this spell, it affects everyone."
Thank you to everyone who answers questions appropriately.
