I was up fairly late just setting up the beginnings of automation on yet another new world when I decided I'd check the forum one last time before bed, and lo, there was this update of huge significance...Needless to say, I was up til about 3 am toying with it, trying to figure out Dragon Orbs.
I have to say I'm stumped and I'm at the point that I would love to have a teensy spoiler/hint, I don't think outside of the box as well as some people do.
Powered Hopper with every filter, including Iron Bars.
Stoked Stewing Pot/Crucible.
Orbs were sucked into a powered filter with a Soul Sand filter, but did not deposit anything in the chest below which led me to believe I would need to use an Urn to collect them, however, with or without any of the other filters the Orbs just pass over the Hopper, and from what I understand using a Soul Sand filter gives you normal XP orbs, not the new Dragon Orbs for further processing.
