I did a forum search for Snake Charmer and I was surprised that I didn't see where someone had mentioned this before. I have experienced this many times and it seems like everyone else has too. My understanding of this fight is if you are hit by his white colored aoe attack, you then hide behind a pillar so the red aoe attack won't kill you. Cool concept, but almost every time myself or someone else in my group is hit by the red aoe attack through the pillar. Sometimes most or all of the group is wiped out from this. It's a bit frustrating when you do what you're supposed to and get rewarded with a 20k crit to the face anyways.
