What mixed hero class of the (Necropolis) faction do you like?

The Lich ages with every attack, including ranged attacks.

The usefulness of the Assassin is debatable – you can cast a mass spell for acceleration, and you can only run away from slow units. For a mage, an earlier turn? For a class that has combat skills, it's not very useful.

In Equilibrium, the Ninja is a hero-beholder – what could be better?

Regarding the Lich with ranged attacks, it's an interesting question. In general, there are many classes that inflict some kind of negative effect on the enemy when they attack, but usually in melee combat. The Ninja can do it remotely. Apparently, the Guildmaster can also stun remotely. The rest have a bonus in melee combat. And since almost all of them don't have combat skills, it's pointless to consider them as fighters.
I'm talking about the classic game. In Equilibrium, there are more interesting bonuses, but there is no fundamental difference from the classic game.
Regarding the Assassin, for whom I voted, I gave a detailed explanation in my previous post. He doesn't need to fight on the battlefield – he needs to survive.
