Wand Focus: Excavation (Thaumcraft 4)

The Wand Focus: Excavation is a wand focus added by Thaumcraft 4. When equipped to a wand, it will emit a green beam of light that will mine blocks of any hardness (except for blocks like Bedrock) from a distance. Its base vis cost is 0.15 per tick that it mines a block. It is also used in operating the Arcane Bore.

 * Treasure: Equivalent of Fortune enchantment. Overridden by Silk Touch.
 * Dowsing: Gives chance of acquiring ore clusters when mining ore blocks.
 * Silk Touch: The focus mines blocks as they are without breaking them into their default drops.
