The damage in the DoS version is huge compared to the NES version.Well, Chaos has 2000 HP in the NES version, and 20,000 HP in the DoS version. The highest damage I've been able to do against Chaos is 3599 HP, done by a Knight in FF Origins, the Normal difficulty. I think the Knight was on level 45 or so. Chaos has 4000 HP in FF Origins, though, so that isn't enough to OHKO him. Other high damage hits: 3807 HP damage against Marilith (in Gurgu Volcano), 5368 HP damage against a Goblin. Both done by a Knight. The highest damage my White Wizard has ever done is 1255 HP damage against a Goblin.
