Forum:Craw Help

I was wondering if anyone out there that could explain the glitch spot for fighting craw, you see i am at work and cannot access youtube or any other similar site, in matter a fact i cannot believe i can go on this site. I play as Roland, and really don't feel like starting a new character, I play offline solo, and i would like to avoid starting a new character. It seems that sirens do have major advantages though. Thank you in advance to anyone who takes the time to explain it to me, keep in mind i have not fought crabby so the area is completely unknown to me, just in the explaination just use landmarks to guide me. Once again thank you in advance, xbox GT SinsterNobody
