Ok so i was in shattrath on my rogue and i'm sitting trying to work out how much ore i'm going to have to farm when i reach 70 to get my engineering up to 350, so i start to wonder around and find this vendor called Wind Trader Lathrai
he sells this schematic called White Smoke Flare which hardly requires anything to make and at 335 engineering it's still yellow so you gain skill pretty much every time you make it.
I personally leveled my engineering from 335 to 350 within the space of 3 minutes with this and it has saved me a crap load of mine farming time, i hope this can be useful for some one else.
I've never seen this posted before, i did search if it happens to have been posted before please provide a link to the post and i will delete this thread![]()
