I solo her in about 5-6 minutes on a disco archer. I disco her, use the rocks, and then keep using tribulations, mortal and ban away with a 100% fire damage bow. I use stone shoes, altered to gargoyle for my human character, so I can be unwebbed in the CC with a dress macro in a second or two. Usually I have her redlined and drop the rocks a second time to finish her instead of wasting arrows. With that said, on Tangles, it's hit or miss. I did her, on a different template, over 800 times (yeah welcome to MY RNG world) before I got my first Tangle. Then again, I've gotten four in a week. YMMV.
