Ok this isnt another go near the apples thread this is serious. I havent had a chance to test this out yet but my friends reported they were able to have the one person collecting get on the ram and ride to the npc to pick them up and while he was doing that he was able to get summoned so he could accept right away and he would only lose 3-4 seconds because you gain about 30 when you turn them in each time. This allows you to get barrels as long as you have a warlock friend with shards.
