Q: Does Valhelsia 3 have Vein Miner or Ore Excavation?
A: No, but there are tools available with vein mining options, such as the Atomic Disassembler from Mekanism. For tree felling, there is the Terra Truncator from Botania. There are also many tools with AoE (area of effect) capabilities, such as the Cthonic Extractors in Tetra or the Terra Shatterer from Botania as well as the Excavating enchant, which can be applied to any pickaxe to give it AoE mining. This isn't an exhaustive list by any means.
