I don’t even know where these are supposed to drop. I have one. Just one. In all my travels of S4 activities. Is probably the one you get from Iron Wolfs rep.
I gave mine away to a noob
Correction, ofc I found my Second ever Stygian Stone at the first world boss I fought today LMAO! Been doing at least 2 world bosses per day since start of season…
sold 19 stygian stone for 17m each since drop rate is low as hell ( one day ago )
