Terra Drill

The Terra Drill (and its upgrades, the Advanced Terra Drill and Schrabidic Terra Drill) is a very powerful multipurpose tool that combines the functionality of a Pickaxe and Shovel, can be recharged, and will never break. It is the most expensive tool in the game, with each level requiring increasingly rare ingredients.

The Terra Drills are most useful for their various abilities. Of these, the most popular are Vein Miner, Area of Effect (AoE), Auto-Centrifuge, and Auto-Crystalizer. You can right click to swap to the next ability, or sneak right click to reset the drill to No Ability Active.

They are directly based off the Drax from the popular game Terraria.

Trivia

 * The internal name of the Terra Drill line is drax_mk1, drax_mk2, and drax_mk3.
 * The name "Terra Drill" is a nod to Terraria's Terra Blade, where many different swords are combined into a single, supremely powerful weapon.
 * Only the Schrabidic Terra Drill has Silk Touch.
 * As Overdrive is to speed upgrades, the Terra Drill line is to tools.
 * This means both extremely useful and extremely expensive.
 * They also share the similarities of using heavy amounts of rare crystals.
 * The hardest parts of the crafting line to obtain are the following:
 * Starmetal Shovel and Pickaxe (long crafting trees).
 * Trixite Crystals (require going to the End or waiting for an Asteroid Mining Ship to bring you one).
 * Schrabidium Crystals (require a nuclear explosion to be set off somewhere in your world).
 * Spark Battery (very heavy usage of Spark Blend and Dineutronium, both endgame materials).
 * Euphemium-Etched Schrabidium Clusters (require a Balefire explosion to be set off somewhere in your world).
