Color sockets

You were able to use a bench to color your sockets you cant do this anymore?

the crafting bench still does this. you have to find the recipes for # of sockets, color of sockets, AND linked sockets in delve. The very first delve you do should award some of them. If you missed them, you can go back to that node and grab them.

yes you can. Socket crafts are associated with progress in Delve content.

How many sockets I can find in Delve ?

I am some deep because 72 lvl depth but I find only some very basic recipes like 2 colour sockets only or 2 one colour and 1+1 different colours. And make 4 socket and only 3 linked sockets.

I no find more on maps (I play T8-9 actually) and in delve not better :(

Where I can find better like 4 sockets linked or 5-6 sockets linked and more important for me 3 or more colour sockets what I need.
Because I need 3 off-colours on my armour so I cant play my build still :(
Help.

thank you for link I check all this places in delve if I find sulphire because I stuck I cant find on maps sulphire to dig deeper in delve.
