School of Blackpowder

Your arcane skills come down the barrel of a firearm and two iron sights. Your spells smell of gun powder and are fueled by lead.

Firearm Proficiencies

2nd-level School of Blackpowder feature

Starting when you choose this school at 2nd level, you gain proficiency with firearms, allowing you to add your proficiency bonus to attacks made with firearms.

You gain proficiency with Tinker’s Tools. You may use them to craft ammunition at half the cost, repair damaged firearms, or even draft and create new ones (DM’s discretion). Some extremely experimental and intricate firearms are only available through crafting.

Spellshot Slinger

2nd-level School of Blackpowder feature

You can channel your arcane spells through a firearm. You may use a firearm as a spellcasting focus.

You gain the following benefits:

• You may use Intelligence instead of Dexterity when making ranged attacks with a firearm.
• Gain a bonus to initiative equal to your proficiency bonus. 
• If you cast a spell that requires material components, you may substitute gun powder for a material component that does not require a gold cost.
• You may use your reaction when you make an attack to change the damage of your firearm to acid, cold, fire, lightning, or thunder. Whenever you do, you may only cast cantrips on your next turn. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses of it when you finish a short rest.

Six Gun Tarot

6th-level School of Blackpowder feature

You can attack twice with your firearm, instead of once, whenever you take the Attack action on your turn. Moreover, you can cast one of your cantrips in place of one of those attacks.

Shotgun Arcana

10th-level School of Blackpowder feature

Whenever you take the attack action on your turn, you may forgo your second attack to spend a spell slot up to 5th level. The attack range is halved, with no long range and no disadvantage within 5 feet. You gain a bonus to the damage equal to 5 x the spell level. The additional damage is force. 

Esoteric Powder

14th-level School of Blackpowder feature

Your ability to weave the arcane into your firearm is potent.
Whenever you cast a spell that requires an attack roll, you may make an attack with your firearm as a part of that same spell attack roll against the same target.

You can add your Intelligence modifier (minimum of +1) to the damage of your ranged spell attacks.
