Weird, because I use my NeoAdvanceRefresher with 10ms (Yeah, 10 Milliseconds) with my Another Account (Yeah!) and I didn't got caught (yeah, spider mode on)
For a Legit way, Open 4 IE and buy: Scarab Ring & Immense Rubber Axe Of DOOM, Then Start the fight, and Use both and attack, change window and do the samething, on the 4th window attack and go back to the first window, it tooks me half a hour to kill him, but it worth the fight ^^
