Tactics for playing as the Sylvan faction.

I still don't understand if the Lion set provides additional empathy... I played against myself, Elf vs. Necromancer. I tried to maintain balance: I gave both heroes the same initial characteristics (only in different sequences, according to the probabilities of their appearance), gave everyone a full set of spells from their school, and gave everyone all the artifacts (then, before the battle, I chose the best ones, as I thought). I even gave the Necromancer skills to weaken Chaos. As a result, the Necromancer heavily defeated himself (although I play Necromancers terribly; I think the main culprits were the vampires, which I somehow didn't add to the list of sworn enemies). Until the Elf hero showed up... In short, he moves around, despite the ballista, and he moves around a lot, I'll say. Even though I lowered his defense to 1 with "Banshee's Cry." The result: a complete victory for the Elf. I'm attaching screenshots of the hero builds and the replay.
P.S. Maybe someone can figure out from the replay if there's a second empathy bonus for the Elf? :)
