Posts from RTF is a global modification that replaces all towns in the game.
Do we need Ashan?
"Frostmourne hungers...":D
According to Ashanov, it's about vampires who ride undead horses and gallop into the sunset, getting beaten up by envious foot soldiers. Also, if you believe the Arantir campaign, it's about repentant paladins who betrayed the light and want to atone for their betrayal through eternal service.
И пусть Эльрат осветит твой путь
As per Ashan's discount on meat, and we have peace - Ashan. This mod will replace all races that are connected by a specific storyline. Depending on it, there will be different creatures. Read the header!
И пусть Эльрат осветит твой путь
In that case, you should give the dead knights the "Drain Life" ability.
It's not necessary; it's difficult to drink blood in mounted combat. It's better to give the "Drain" ability only to the Greyd and recolor his sword to match the Bloodletter's sword style – then it will be clear how he regenerates. Also, add a helmet:D

As far as I know, Heroes 5 isn't entirely canonical compared to 6 and 7, as the Ashan universe only appeared in them. So, the neutral Death Knights have no reflection in the canon. It's a completely different matter that the hero class of Necropolis also called Death Knights. Hence, the conclusion is that Death Knights are just a type of necromancer.

At the time of the mod's events, the vampire knights created a base in Erathia; most of the recruited knights are captains of the Black Guard mercenaries, but after Arantir's death, their loyalty wavered, and Death Knights appeared, similar to those in Heroes 6 - vampires who have not reached the super level after which the body disappears, but are already ready to crush everyone.

Can the draining ability be made to restore health as a percentage of the killed unit? That is, there is a stack of 100 peasants, a knight killed 70 with the first blow, but did not heal, and when he finished off the rest, he healed as a percentage of the remaining 30.

By the way, about the heroes. What will the hero models be? Only the amount of health restored can be changed in the draining ability
