Damn Solaire (S&O Boss fight)

So, I'm in NG+, the first time I fought Smough and Ornstein I killed Ornstein first and I wanted to do the opposite for my NG+ run. Well, since I'm a heavily armored strength-based bruiser, I found it difficult to focus on Smough while Ornstein was constantly jumping at me.

I summoned Solaire, hoping that he would keep Ornstein off my back while I killed Smough. Long story short, he killed Ornstein before I could finish Smough off, dead in less than a minute. I had a +15 Zweihander and I couldn't out-DPS that sun-worhipping headcase! Super Smough was trivial, as always, which now means I have to wait for NG++ in order to get Ornstein's stuff.

SPOILER: I took it out on Dark sun Gwyndolin, destroyed his illusion and him. I do feel moderately better now, though.

You can always teleport out of the boss area before you kill any boss if you don't get the result you want, and Knight Solaire, is indeed strong, thought I noticed that his power vary depending on the boss he is helping you with.
