Tera - brnm turtle gunner solo (part 1)

I have over 200+ runs in brnm/brhm so I figure why don't I try to solo on gunner and see how far I can get. Was trying to see do I get an achievement for trying but sadly there wasn't when I finished this whole dungeon solo.
I think when turtle did his shield a 2nd time, I didn't expect to see it so soon and my baldurs vengeance skill I landed it wrong on him.
It hit side so it didn't fully crit lol, fail lol. I even failed on his 3rd one as I didn't expect to see a 3rd lol. It's so critical to save the most strong attacks for that.
My gear is all disco (weapon intense) except armor which is ambit +12. I only had buff from priest outside dungeon so I was able to use it only for 1st fight, rest of fight i just use charms and whatever I had. The other 2 parts will be in the other videos.
