Which monster do you like the most in Heroes 5 (level 4)?

I meant 3 Earth Shocks at once. And it takes the Dark Elf 3 turns to do that. Let's calculate how much mana it will cost for each... Earth Shock costs 18, as far as I remember (correct me if I'm wrong). So: considering Arcane Wave, it's 108 mana. For the Sylvan Elf, it's 54. But the Dark Elf can upgrade skills that reduce mana costs. And if the hero is a Sinister, it's even better. At level 20, the Sinister's mana costs are reduced by 25%, plus the skill reduces it by another 20%. I'm not sure about this. Either they add up first and then the price is calculated, or they are applied one after the other. But the total damage will definitely be greater for the Dark Elf.
