I started farming when I was home with my daughter for a month ( thank you family medical leave act) after she was born. Babies sleep a lot. Daddy got to play video games a lot. Two weeks. No other goal, no other game. Two weeks to farm that. To anyone who has complained about a trident in dark I always think to myself " go **** yourself"
I actually chuckled when I read the Dark Souls wiki and confirmed that all the slabs I needed were hidden somewhere and not random drops.
Edit: For a frame of reference, I think I went from sl 180 or so to mid 200s just doing the short run to kill theone skeleton repeatedly
