The second battle with Agahnim beaten without taking damage. Played in real time on Snes9x v1.43 rerecording.
The same rules apply to your second encounter with Agahnim as the first, except that you don't have to worry about him casting lightning. What you do have to worry about is his two clones, which are slightly transparent, who will also be shooting fireballs at you. You'll still want to stand to either side of the real Agahnim when hitting his fireballs back at him, to avoid being hit by the blue rings, but now you'll usually have to dodge a fireball or two from the clones before that.
Don't bother trying to deflect all three fireballs unless you can get in a good position to do so. They may be big, but the they move slowly so they're usually easy to dodge while getting into position to hit the real Agahnim's fireball back at him. As long as you don't get careless, this fight is easily won.
