In this video I talk about the Arcane Bore. Like how too use it and what the different enchantments do to the mining.
Stuff that i missed to mention: The arcane bore takes 1 vis for every 3 blocks mine. If the chest fills up the bore wont stop the blocks it mines will drop on the ground. It's probably not a god idea to have many bores at one spot, it will only drain the aura faster and stop the bores from working. It can mine in 6 directions, not only the the 4 i showed. The arcane bore can be put on or under the base. You can eave have two bores on one base. One on top and one under it. Arcane bores work on frames.note that they need like one second too start working after a move.
I'm using the Direwolf20 mod pack V5 from the Feed the beast launcher.
