Djinn are good a little later in the game, when there are enough of them to summon a large number of illusions. Then, for battles, it is enough for the hero to take only Djinn and the Original for the illusion :). Four slots with one Djinn each for "songs of the world" and put all the rest in the fifth slot to copy illusions from the Original. Well, and the Hero himself in the seventh slot :)
I didn't think of such a tactic, I'll have to try it when I get a computer))) In general, Djinn and Water Elementals are the main opponents of vampires, they kill him very quickly.(((
Illusions are useless when you are against Death. The enemy hero knows "Dispel Magic" or "General Dispel Magic". And your Illusion will simply cease to exist. And it will be hard for your original. Regarding the main opponents of vampires: these are water elementals and djinn - I don't argue. These are creatures of the 3rd level. But regarding the 4th level, the conversation is different.
P.S. I would add the Mage and the Sorceress to the main enemies of the vampire.
