The main thing I've been doing for the past several weeks has been branch mining - a lot of it. I've been mining down at Y11 in an area west of my base, mainly for diamonds. Before I started this, I had around 4000 diamonds in my Refined Storage system; I now have around 5900. I've been using a Silk Touch Tinker's Cobalt Pickaxe for this, and also mining redstone ore this way. Redstone ore when pulverized has a chance of creating Cinnabar as a secondary output. This can then be used in an Induction Smelter to triple ore outputs, with a 75% of producing Rich Slag as a byproduct. It too can be used for ore tripling.
Gold also produces Cinnabar as a secondary output when pulverized, though with a lesser chance than redstone ore.
A screenshot of all of the tunnels, which are 2 blocks apart:
The larger tunnel running E-W is 3x3. The Fluxbore from Thermal Expansion has several mining modes. 3x3 is one of them. It can also mine a 1x2 tunnel. For lighting, I am using a Torch Launcher from Cyclic, which I put Unbreaking III on. This gives it an effective durablity of 768. Like other tools from this mod, and a lot of other tools from other mods, it can be repaired in either a Magma Anvil (uses lava to repair items) or a Powered Diamond Anvil (uses RF/FE to repair). It is very useful for lighting up caves from a great distance, and could come in handy in a dimension like the Deep Dark from Extra Utilities 2.
I'm considering doing all my mining in the Mining Dimension, which I have not visited in a long time.
All the time I have been mining, though, things have occurred at my base. One of those were a couple of Shooting Stars from Astral Sorcery. When these land, they explode with a force greater than that of TNT. This is the approximate size of the crater they leave behind:
Another of these landed inside my base, but fortunately only destroyed some grass and one Refined Storage cable, easily replaced.
I had un-claimed all the chunks around my base in order to troubleshoot the framerate lag around my Astral Sorcery area and forgot to reclaim them. I have since done so.
There were also some fences at my animal pens and some logs around one of the farm areas near the village that were destroyed by lightning. Forestry adds fireproof woods, made using a Thermionic Fabricator. This uses molten glass along with Refractory Wax to make the wood. The wax is gotten from centrifuging combs from Nether bees.
I replaced all the fences around the animal pens with their fireproof equivalents. I am considering doing the entire walkway on the outer walls of the base eventually. When I rebuilt the house, all the wood I used was fireproof.
