Undead Dragon Advice

[Makeithappen]

I'm calling ♥♥♥♥♥♥♥♥ on this one.
On SP.
I'm getting him to 45% health consistently, but then he starts spinning his character model to follow me even when I flank him to get out of the way of his fire breath. Its like he has auto target lock on me and I cannot avoid getting one shotted by this.

I can dodge just fine with Silent legion armor and I'm using a 2handed Telith sword.
I bring Ambrosia and aloe soup with me as well as some exotic food in case I run out of healing.
I have it down to a science on his pattern and i can get 1 and 2 hits on him respectfully.

I am fighting out in the open area of the Sinkhole. I'm only flanking him to dodge all his attacks and moving out of the way when he does his AOE attack. When he breathes fire I usually move to his hind legs to avoid the cone area.
Am I doing something wrong to avoid his fire breath? should I be rolling under his head when he auto locks? This has happened several times and there doesn't seem to be a way to avoid this.

Maybe I have the wrong armor or special fire protection potion I am not drinking. Anyway asking for any advice on here that someone could give me.

1: Take a thrall with you to take the aggro or 2. change to shield for the breath attack.

Yeah I might take one of my named thralls with me next time. Hmmm I don't know why I didn't think of using a shield. duh me. I'll try that next time. Thanks!
