They can be reliably parried.

I disagree on the entry point... if you're familiar with the area, entering from Valley of the Drakes is MUCH much better, purely because of the amount of time it saves to get there if you come down the elevator from the Darkroot Forest bonfire. If you're talking about farming Darkwraiths for hours until you get a slab (and it most likely will take at least an hour or two unless you're very lucky), your time is very very valuable lol so the 30 second route to get there trumps any other route to get there. It will take a couple of tries to get the timing correct, but once you've done it a few times, running past the Drakes is a peace of cake and is truly necessary to get slabs as quickly as possible. The only thing about entering this way as that a Darkwraith will see you as soon as you enter the area anywhere on the left side, and the Drakes can follow you inside if you aren't careful. This route is definitely more dangerous, but once again is a necessity to save time. Look up videos on youtube and pay attention to how the pros do it.

410 item discovery
Symbol of avarice or gold serpent ring + 10 humanities

Yeah I agree with the other person, 410 Item Discovery for this is a must or you'll truly be there forever trying to get these.

You only need 10 humanity for 410 item discovery

Not on the unpatched version... with Unpatched you need 30 Humanity, Patched is where they lowered it to 10!

lol yeah, I was trying to get my armor to +9 for NG++ so I could be 100% ready, after 30 min of farming I had 4 slabs and 3 hands, and 0 chunks... I guess I'm going for +10 armor then!

OP here, after much farming, Getting 2 chunks is possible, but getting only 1 Chunk is far more common

As of 30 minutes ago they do.

2 dropped at a time for me just now
