Kill 50 Ashweb Spiderlings. Use Kun's torch to burn them inside their pods.
Okay, these spiders are seriously creeping me out. Especially those egg sacs they leave lying around that I keep accidentally stepping on only to be covered in very little but very creepy spiderlings. Ug, makes me shudder just thinking about it.
I say you burn them. Burn them all.
