I'll try to outline my hero development strategy; I ALWAYS play as Vlad (also known as Vladimir).
As everyone knows, Vlad starts with necromancy and summoning magic, which is very useful given his ability to resurrect fallen undead. As the hero levels up, I have several options:
1. Take the "Raise Archers" skill to gather not just weak skeletons, but useful skeleton archers.
2. Take the "Education" skill to gain more experience and quickly develop the other skills. Also, "Mana Attraction" is a very good skill for a necromancer, whose focus is on magical power rather than knowledge. This solves the mana shortage problem.
3. Take the "Haunted Mines" skill and create an army of ghosts from thin air; ghosts are not to be trifled with!
I mainly focus on developing the skills listed above, and then I take the following skills:

1. Defense
2. Offense
3. Logistics

Defense is an incredibly useful skill for necromancers; losses among skeleton archers are significantly reduced, which is important when their number in the army exceeds 2000. The "Evasion" skill is also very useful, especially during a castle siege. Combined with "Raise Dead," it yields good results. :)

Offense:smile10: This skill has huge advantages for the undead. Again, "Battle Frenzy" doubles the damage of your archers, and the "Archery" skill adds an additional 20% to the maximum damage from archers. As a result, the enemy will have to attack the skeleton archers with all available forces and suffer incredible losses from your melee troops, whose damage is increased by the "Offense" skill by 30%.

Logistics is also a good skill, but it is best to take it on large maps; on smaller maps, this skill is not very effective. However, "Navigation" and "Scouting" followed by the "Silent Hunter" skill are not worth taking; it's a waste of a level. :smile18:

As I was writing this post, another question arose: each hero has core skills specific to their class ("Raise Skeleton Archers," etc.), and also one special skill! So, at what level does it become available? :smile39:
