As a reminder: in the case of unit regeneration, a situation arises in one-on-one battles where a unit can defeat a much stronger detachment.
At the same time, if it clashes with an identical unit, the battle does not end. That is, it continues. Until someone gets bored :)))

AmberSoler, a rare case where I disagree.
Against 4 (living) detachments, I would prefer exactly 1 detachment of 40 Vampire Lords rather than 4 detachments of 10. Naturally, exceptions exist, but in most cases it is exactly like that.
By the way, AmberSoler, why don't you ask for moderator rights? Personally, it seems to me that this would be very useful for the forum ...
Respectfully,
