Inferno tactics.

Frankly, I don't understand why you're all comparing Inferno to Castle! Do you really think Castle is the strongest faction in the game? In my opinion, nothing is better than Conflux, especially with the hero Ciel. In our local tournaments, this hero was even banned due to his obvious advantage.

I've already described the struggle against Conflux in the thread "Who is stronger: Tower, Necromancer, or Conflux," and I'll add that Ciel's bonus is effective for the first week and a half, maybe two weeks – after that, you can consider that she has no special abilities at all. And you can't defeat everyone with ranged attacks.
