I made this Shadowy Shank farming guide to help out players who want to farm meat instead of buying them from the Auction House. I traveled around the Shadowlands to search for places with a high density of mobs that drop Shadowy Shank. Below you will find a list of places I think are the best for farming Shadowy Shank.
One mob can't drop more than one meat, and the drop rate of Shadowy Shank and other Shadowlands cooking ingredients are a lot lower than the BfA cooking materials drop rate was. Don't expect getting as much meat as in BfA!
The best way to get a lot of Shadowy Shank is by farming Gorm Raveners at Northwest of Glitterfal Basin. They respawn extremely fast, and you can always pull at least 3 of them together. They hardly do any damage and they have low armor.
The Tufted Bonesnout also drops Tenebrous Ribs, so make sure to kill those too when you see them, but there are only a few of them there.
