"Necropolis" - changes to creatures of levels 6-7.

The damage from the Shout ability is primarily area-of-effect damage, meaning it's difficult to apply, and therefore it should be many times more powerful than a direct attack.

Regarding the deadly strike, again, if the stack of Royal Sentinels is comparable to that of Champions, then it will deal 250 damage per strike, so it's analogous to a simple double strike ability. The fact that small stacks of Royal Sentinels (relative to the target) are dangerous is true, but even more effective are small stacks of caster units, such as witches.

Regarding the Shout ability, I agree.

Yes, this is if the stacks are comparable. But what if three Royal Sentinels emerge against one Knight? The benefit is greater than that of witches. On the other hand, I don't deny that sometimes(!) this ability will be effective against them. But still, if we consider Multiplayer, I think Necropolis will ultimately be the dominant faction. When it comes to a battle between two heroes, Knights with high speed and initiative will tear him apart. Moreover, even if there are very few of them left. As a result, the opponent will have to waste an extra attack from archers to finish off the remaining 1-2-3 Knights, who are already approaching the Paladins, instead of fearlessly shooting at the vampires.
