Expanded Spell List
Starting at 3rd level, you always have certain spells prepared after you reach particular levels in this class, as shown in the Miner Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

Arcane Drill
Also at 3rd level, you have developed a specialised tool to aid you in both mining and combat. Over the course of a long rest you can use your Tinker's tools to create an arcane drill. You can only have 1 opperational arcane drill at once and the arcane drill has the following properties;
Arcane Drill
melee weapon (unique)
Category: Items
Damage: 1d10
Damage Type: Piercing
Properties: Heavy, Special
Weight: 4
Arcane Tool. The arcane drill uses your Intelligence modifier for attack and damage rolls and can be used as a spell casting focus.
Driller: While wielding this weapon you have a burrowing speed of 10ft. but you cannot burrow through solid stone using this weapon.
Stone Breaker: Your arcane drill deals double damage to constructs and structures.
Extra Attack
At 5th level, you can attack twice instead of once, whenever you take the Attack action on your turn. Additionally, your arcane drill counts as magical for overcoming resistances.
Excavator
At 9th level, while wielding your arcane drill your burrowing speed increases to match your walking spell but you cannot burrow through solid stone.
Additionally, as an action you can expend spell slots to charge your arcane drill to perform one of the following techniques.
Pitfall. Target a spot you can see within 30ft. of you. Creatures within 10ft. of this area must make a Dexterity saving throw. On a failed save, creatures fall as a 10ft. x spell slot expended deep pit opens up beneath them taking 1d8 bludgeoning damage for each spell slot above 1st expended. This pit remains for 1 minute before filling in and harmlessly expelling any creatures or objects within.
Mine Collapse. Creatures within 15ft wide 30ft. tall cylinder centered on you must make a Dexterity saving throw. On a failed save, creatures take 1d10 bludgeoning damage for each spell slot above 1st expended as earth and rubble rains down on them and quickly clears away. Flying creatures who are hit by this feature fall to the ground and take an additional 1d10 bludgeoning damage. If this features cylinder overlaps with a ceiling the affected area increases to 30ft. wide.
Tunneler
At 15 level, while wielding your arcane drill it is improved in the following ways;
- You can burrow through solid stone as if it where difficult terrain.
- You can choose to create a supported mineshaft using your arcane drill. When using this feature you move 10ft. every minute creating a 5ft. wide tunnel behind you as you move.
- Your arcane drill deals 2d10 piercing damage.
