I don't come to these topics much very often, but I wanna dispel a certain claim...
That is, the fact that Edgar *NEEDS* confusion to win this fight. This isn't actually true, however. Reason being that Poison causes Air Anchor to kick in as well.
IOWs...
Zidane does Doom
Edgar uses Air Anchor
Zidane waits
Edgar uses Bio Blaster
Zidane waits
Poison damage on Zidane kicks in
Air Anchor Self Destruct kicks in -> Zidane Dies.
Why this works? Who knows, FF6 has a lot of weird bugs like this, but its there, and it works in all versions of FF6 I believe (FF6a may be an exception?)
So anyway, Zidane would need both Clear Head *AND* Antibody. So unless there's an equip that allows BOTH, that would kind of be unfair, as I know most people are under the opinion of "One status protection Accessory (or equip, in some cases)", unique equips not withstanding, so yeah.
Just thought I'd toss that out!
