Inferno tactics.

Yes, demons are unstable, that's why they represent chaos. The Kre'gan are not a simple faction, that's for sure... Constant attacks are the key to success for Inferno, and here are some useful skills: Wisdom, fire magic, attack, tactics, leadership... Basically, everything in that vein. In the first week, definitely include an Efreet, Gogs, and a Cerberus, and then do as you wish. Otherwise, you're doomed. This is just my opinion, but it was specifically developed for the forum after playing Inferno for two weeks.
