Yes, the number should definitely be higher. At least 0.3 * hero level. So, at level 40, there will be approximately 12 banshees, which is quite small; it probably needs to be even more.

SummonCreature summons to a free random point without coordinates.

I will change it to a larger number.

A problem has arisen! In the original Heroes Campaigns, in the fifth mission, after Godric frees Isabelle, Agrail attacks the Castle. I decided to implement the same function in my scenario, but the dialogue scene plays BEFORE Vittorio attacks the Castle!

function ChristianAttack()
DeployReserveHero("Christian", 98, 108, 0)
sleep(10)
MoveHero("Christian", 126, 139, -1)
if IsHeroAlive("Hafad") then
    if IsHeroAlive("Christian") then
        if GetObjectOwner("castle") == PLAYER_2 then
            SetObjectiveState("prim5", OBJECTIVE_FAILED, 1)
            sleep(10)
            loose()
    else StartDialogScene("/DialogScenes/FallenKnight/S3/DialogScene.xdb#xpointer(/DialogScene)")
		     sleep(1)
	       SetObjectiveState("prim5", OBJECTIVE_COMPLETED, 1)
         SetObjectiveState("prim6", OBJECTIVE_ACTIVE, 1)
         end;
    end;
end;
end;
