Comment by Ryawy

"Could you go pick up some Shal'dorei Silk from Val'sharah?" I have some with me.

"There is some silk over there on those crates. Don't take too much." I still have some with me.

"This silk is in no condition to bring back." I still have that silk with me.

"This task is below me, but I'll do it for you if you mix me a thing." I don't really have to be here.

"Thanks for bringing me that silk for my filters!" I literally have three stacks in my bank.

Comment by Boxofbeer

Get back to Deucus Valdera and give him Mended Shal'dorei Silk.
