a bonebinder  

if you are just after the silks go after the bonecrawlers, its a bit easyer if you are'nt over lvl 12

I can confirm that there is a lil cave just left of of the path from cabilis, there is a lil rare spawn spide, about lvl 3 or 4 who will pop in there is u kill enough normal spiders (of a similar lvl, maybe 3 or 4 max goin as low as one)
normal spiders will help each other in a fight, but will not help the burynai bane spider (who btw will con kos but not aggro)
the named spider drops the burnai bane spider fang, magic, effect sear (a nice lil dot) it's stats are roughly the same as a giant snake fang, it is only useful due to the dot and magic.
it also drops a charm (neck i think) and a poison sack or something similar for off hand.
just my 2 cp

Up until level 20 the bonebinders still con blue to my Monk. Now at 28 I can whack them in a few rounds. :)

u got it all wrong kaemean u were killing bonecrawler's not bonebinders. close names but there are different they coned yellow at lvl 10. con black at 13 around and i am now lvl 15 and they con blue.

Killing bonebinders now, some are blue to lvl 12...so i think lvl ranges from 11 up, but blue ones are rare

The insects in this area look pretty much alike, are you guys sure that you conned Bonebinders??? They were red to my lvl 10 Iksar monk, some yellow at lvl 11 now...

I accidentally pulled one of these while I was hunting carrion shredders (they group btw). It conned red to my lvl 7 shaman.
