Playing as the Stronghold faction (Disciples 2).

True, werewolves are expensive, and in this game, I personally never have enough money((((
In my opinion, it's worth it. You don't have to rack your brains and think about where to get just a little more experience, even for an evil spirit.

No, it's not worth it. Five hundred, if I remember correctly, for the building, and another thousand for a stoic werewolf, which dies from two elemental attacks and is vulnerable to magic. Maybe in the campaign, on "very easy," when you start with a thousand, you can buy it. But it's still an unjustified waste of money. And in a skirmish, such a player has a whole bunch of them.

And the tactic with ghosts and undead is for newbies. It's good for farming neutrals, but it's completely useless and losing against a player, and dwarves tear apart such an "army" in two turns.

but the Cerberus is the strongest of the tailed ones and is easily defeated by Undead, which are immune to it

It's immune to death, so they'll lose. Pff, that's old.
