yeah just tell bot to pick up blues and arcane dust, if i remember, at default i dont think it picks up arcane dust, maybe it does, but i think i had to tell it to do so, been awhile. Run act4 bounties, set it to pick up blues and salvage them, i have 4k arcane dust now, so i turned picking up blues awhile ago, when i get low, i just tick it on and continue, same for the veils, if i run low i salvage rares, but i have about 4 or 5k of those now too, and i rarely craft since i have almost everything on all my toons made, so i have a mule that holds it all, then it just sells all yellows, make more gold that way too
