The Omen is a balanced medium energy turret cruiser, with a decent velocity, targeting range, and drone bay. Its six low power slots give it plenty of room for a strong armor tank.
The following fits are intended for young players who are just training into their first Amarr combat cruiser. The cost should be under 30 million ISK in a trade hub such as Amarr.
You'll want to train Amarr Cruiser and Medium Energy Turret to at least level 3, in order to run combat sites like the Blood Raider Intelligence Collection Point or Sansha's Command Relay Outpost. The beam laser fit is capable of completing the Mul-Zatah Monastery, so long as you keep your distance from the stasis towers and mob of cruisers.
Engage at a range of 10 kilometers with Multifrequency crystals, or 25 kilometers with Radio crystals. Use keep-at-range against frigates or destroyers, or orbit against cruisers or larger ships. The ship is cap stable, so the armor repairer can be run indefinitely.
