Heart of the Night

in one of Karlam's chests, he found a Ring of Exile. At first, he thought it was intentional, but it didn't appear in other chests. By the way, in the next chest, he found boots that provided 10% magic resistance.
Okay, he was happy about it and, using cheats, rushed to Gilva to check how it works.
In general, it doesn't work, although it should. When we destroy her unit, it then has the "summoned" status, and in theory, she should resurrect them in a smaller number, but there is absolutely no difference with or without the ring. The Exile ability is weak; it's only useful at the very end when there are many different small units and single units left, and when our mana is already depleted, so you can cast it a couple of times to get rid of them all at once – that would be useful, as it will save many turns and some troops.
In general, I don't even know; I'll have to think about it.
