They stand in a deep defensive position and resurrect, even though they could quickly finish off the enemy, but they drag it out to fully and freely restore all their losses.
It's not 5 shots, not 10, and not even 20, but 100, meaning it's specifically designed to be unlimited!
The most annoying thing I've seen in Disciples 2 is exactly this kind of healing when playing as Humans/Elves. While you're blocking and healing, and at the same time killing the enemy with archers, that's normal. But if you leave the enemy's last unit alive and start healing faster than they can attack, and the archers just skip their turns, it starts to feel like a perversion. And you can't give it up because it's effective (free and unlimited).
It's easier to compensate for the percentage of losses with scripts, if a tent is available. For example, like this: reduces losses after battle by 10/20/30/40% (depending on the skill). It will be almost the same, only without wasting time.
