Template:FFIV:TAY Enemies Ahriman is an enemy in Final Fantasy IV: The After Years. It is defeated by Cecil Harvey, Rosa Joanna Farrell, and Cid Pollendina during Baron's invasion, in a storyline battle.
the weaker Ahriman shouldn't prove to be too much of a problem. He will cast doom first, and then cast haste on the person he inflicted with doom to speed up the count down. Band abilities as well as having Rosa cast slow on Ahriman will help make the battle easier.
On the other Hand Ahriman fought as a boss during the Crystal story is a different case. He'll Cast doom upon everyone, and then follow up with Haste. Bring on member In KO status in the fight, and then revive them after Doom has been cast. From there as long as you keep on reviving party members, you should be fine throughout the fight.
