Inferno tactics.

Inferno, in my opinion—and not just mine—is a rather weak castle. I play it only if I'm tired of all the other castles and want something different, although that happens very rarely. As a rule, this castle is not designed for long games, but for a quick rush against the opponent; if you are playing on a small map, you have every chance to win. The main thing is to take a warrior hero, for example, Pir or Rashka, and focus development on the army—meaning building fast Efreet and Devils. The key is not to drag out the game and try, at least attempt, to attack the opponent by the end of week 2-3, but definitely not to sit back and hoard an army, because in the late game you will have much fewer chances to win due to the low HP of Inferno units and other drawbacks. Essentially, this castle is created for playing on small maps; on large ones, I would advise capturing any other castle as quickly as possible and developing it.
