Cra-rachnee arrows

(draft, feel free to add/restructure)

It's a quest you get from Ant Eruchneum inside the mine in Astrub City at 6,-19 (where there's also the entrance)

Kill as many spiders as you can to get the requested spiderlegs. Or you may be able to buy them at 4,-17. The more spiders you fight at once, the more likely it is you actually get spiderlegs. There's a good spot at 4,-21 with three lvl 1 spiders to kill, it earns you a leg almost every fight if you do it alone.
