Drills are mining tools for rock-based materials. They can use the same Enchantments and Reforges as pickaxes do. They also have a Ⓟ Breaking Power just like pickaxes.
Drills require Drill Fuel to function. Most blocks cost 1 base fuel to mine. Aquamarine, Citrine, Onyx and Peridot Gemstones cost 2 base fuel to mine. Glacite, Tungsten and Umber cost 3 base fuel to mine.
The remaining Drill Fuel can be seen on the action bar.
Drill Parts are additional upgrades for Drills. These can be combined to a drill using a Drill Anvil. There are three available categories of Drill Parts, being Fuel Tanks, Drill Engines, and Upgrade Modules.
Fuel Tanks[]
Fuel Tanks are used to increase the amount of fuel a drill can store. They also decrease pickaxe ability cooldowns.
If player wishes to progress via ⏣ Crystal Hollows, they should use the Gemstone Drill line since they're cheap and grant very useful ✧ Pristine as well as other bonuses when mining Gemstones.
This is true until the player can afford Titanium Drill DR-X655 which is universal and the second best mining tool, due to it having a slot for Topaz gemstone, unlike its predecessors.
On the other side, if the player wishes to progress through ⏣ Dwarven Mines, the Titanium Drills become a good alternative to Mithril gear.
Notes[]
Extra blocks mined with the Efficient Miner HotM perk do not consume extra Drill Fuel.
Trivia[]
On August 23, 2022 all Drills would give 50-550 (depending on Drill Engine) of each stat due to a bug, this was fixed minutes later.
Mithril Drill SX-R326 is generally not recommended, since it has low Ⓟ Breaking Power, and is very expensive for its stats. The First Mithril Drill on the other hand is much cheaper and as a Drill gives the player the access to the powerful Drill Parts.
