And here's one more.. had to get it out of the google cache ...
Necro guide
Drachnid Thyxl This one drops of a rare spawn, the dread widow in the spider camps at (- 5000, 1500) and (-5000, -1500) in the Dreadlands. Due to harm touch and the high amount of hps it is quite risky to take it out on your own -together with a partner it is easy as long as you both are level 49+. You actually need to kill pretty anything with eight legs inside one of the spider camps (she can spawn in both of them). Aproximately every 3-6 hours the Dread Widow (level 46-50, Shadowknight, 12296hp) spawns and
always drops the thyxl. It’s no drop and has got a nice GBS (now where are the veterans?) look.
