I don't know if this thread was made before, but I've come across a few people who say they get killed by Xaldin's desperation dragon attack very often. I was fighting Xaldin before making this thread and as I was fighting him I used a different strategy. There is no way to completely avoid it, but this is the best way to take the least damage from this attack. When he does it, wherever you are don't be in the middle of the bridge or anywhere but the end of the bridge, because when he does it, he will make sure the attack is in effect until you reach the end. If you are at the end of the bridge (and make sure your at the end he is heading towards) he will only damage you a little. I hope this helped, because it sure did help me.
