The "deadly strike" ability cannot be considered imbalanced unless you use a cheat in the form of constantly saving and reloading to manipulate the random number generator.

But 4 units of tier 6, yes, that's an imbalance.

It's not really fair to simply reduce half of any stack, regardless of its size, with only a 25% chance, without checking the ratio of parameters.
We give a weak hero a Random Skill, divide it into several stacks, and we get a chance of at least halving the stack once: 44% for two stacks, 58% for three stacks, 68% for four stacks.
If the ability worked with a standard check, I wouldn't have any complaints about it. :)

Using the same logic, one could argue that a single caster unit is overpowered. It's "not quite right" when 1 monk casts a buff on 10 angels.

Or when 1 paladin removes mind control.

Or when 1 peasant removes retaliation or blocks the path for a group of knights. And so on.

There are things that play a role in certain situations, regardless of the amount of units, and this is a perfectly normal phenomenon, in my opinion. The fact that they are supposedly imbalanced has not been proven by anyone yet. Some people simply like this state of affairs, while others don't.

As far as I remember, the Necromancer's speed is not 8, and corpses don't trigger retaliation, so the chances of actually hitting anyone in the aforementioned scenario are quite slim.

If we're talking about breaking through, then it won't be possible to break through for long in this way, unless with cheat loads. And the effect of halving is also questionable in this case, because if there are few Necromancers, they won't be enough to finish off even the halved stacks. Especially since when attacking достаточно strong neutrals, there will be many stacks.

In short, the overpoweredness of this ability, in my opinion, is a myth.

These abilities trigger for all units depending on the ratio of the attacker's and defender's parameters.

Not 8, but 7+Tactics+boots+Aura (rarely). Plus - RD + BDP (Necropolis). There are plenty of chances.

We're talking more about a cunning hero.

Hmm, I like the idea of giving Veres knights without the deadly strike ability. For example, black knights, after removing that ability. But with the possibility of upgrading them at the Fortress for a good price.
As a result, this ability can be made useful and less random (level 6 creatures in the early game, a small number of creatures with deadly strike in the late game, which can be a nuisance for the enemy in the final stages, but a nuisance that can be countered if desired).

As for Veres himself, here's how a possible adjustment to his specialization might look (a couple of options off the top of my head):

A deadly attack also has a negative aspect: when dealing normal damage, Death Knights can eliminate many more creatures...

There is also a negative aspect to the deadly strike: when dealing normal damage, Death Knights will destroy a much larger number of creatures...

As far as I remember, in that case, the ability definitely won't trigger. That is, the attack will always be advantageous.
