So uh, how do I stop the Adra Dragon from knocking down my party followed by a one shot breath kill as soon as the fight starts? I don't even have time to use buffs. And of course they had to have Ads. Do I need 100 reflex or something?
He's not immune to one of the mind control spells, I believe it was confused. So if you can confuse him or confuse the Adragons, you can get them to fight each other.
The breath is frontal cone, so if you stack then he hits everybody, but he also has a tail swipe.
I would chain confuse until you run out of stacks. Wipe out the Adragons by focusing them one by one, then spread out around the dragon and spam raw damage.
If you can't beat it at that point, what level are you? I initially got to him at 11 iirc, thought it was impossible, and came back at 14 with better gear, it was not bad at that point.
