you can kill them easily with a mace, (blessed if you want to kill the white eyed bastard and cancel his res entirely) They get knocked down very easily and you can chain it.
When others said "use strike weapon", so i used Fist/Caestus.. punching him in fury, and... the screen get darker, with 2 red big words..
White Eyed one in Carthus Catacombs after the bonfire through the illusion wall rarely Drops Large titanite Shard as well.
If you're struggling with the ones at Smouldering Lake right before the Crossbows, just running past them works fine. Their aggro range is very limited.
I came here hoping I could farm their attire but no :(
