No one's going to notice you're not here, it's much too crowded.

I entirely agree that you should not go out in search of juvenile acromantulae; even the cat-sized ones will happily eat a human. They'll just, you know, share.

Acromantula silk is considered good for healing if you happen to get your hands on it while it's very fresh, but overwhelmingly it is also considered to be NOT WORTH the RISK.
