Which monster do you like the most in Heroes 5 (level 6)?

At first glance, based on their stats and abilities, Paoka seem strong, but I think over time, the enthusiasm for them will fade, and they will be treated similarly to Archdevils (they might be decent units in terms of stats, but you can't expect reinforcements from them!).

Yes, I agree. I'm playing the second mission in the second campaign, and the Paoka aren't very strong. They get killed easily because Battle Fury doesn't affect them, so their damage isn't absorbed. For example, in a battle with an Elven hero, he didn't deal damage to my Cyclops; he just consumed 91 points of Fury. So, it's a pity that Fury doesn't affect Paoka, but they do deal normal damage with their lightning.
