Mmmm... Smite Crawler blood....is....Good

I finally found the path on my own to the smite crawlers after looking through threads here on guru. It wan't any worse to get to the smites as it is to get "clear the chamber" - minus clearing the terrorwebs.

I managed to kill the first set of three smites after a while(I wasn't wanding them at first, which seemed to make all the difference). So, I adventured a little farther out into the open air to pick up a mob of four smites. "No biggy" I told myself, since I didn't notice any interupt skills on the first set of three. I went down in about 10-15 seconds. *Sigh* I died right after casting protective spirit, followed by healing breeze. Immediately after casting breeze my health went straight to zero. I didn't notice any interupts, which is why I am looking for an answer to my following question:
What skills could they have used to pawn me so badly? It was as if I was in the presence of a dying nightmare or the equivilent. Are there any dying nightmares out in the open smite area(I hope not)?
If there aren't any enchantment shatter-ers out there, perhaps I just clicked through p.s. -> healing breeze too fast. Lol, I hope not though.

P.S. Here's where I ended up dying; at least I'm making progress.
