Explosives Expert

An Explosives Expert is an artificer who specializes in utilizing the destructive capabilities of gunpowder. This power is often used on the battlefield to wipe out hordes of soldiers and demolish enemy fortifications. Many people who meet an Explosives Expert often ask what differentiates them from an Artillerist. They typically respond with a straightforward, simple answer: "Artillerists focus on launching things. I focus on making things go boom."

Tools of the Trade

You gain proficiency with heavy armor, due to your time around explosives. You also gain proficiency with woodcarver's tools. If you already have this proficiency, you gain proficiency with one other type of artisan's tools of your choice. 

Explosives Expert Spells

You always have certain spells prepared after you reach particular levels in this class, as shown on the Explosives Expert table. These spells count as artificer spells for you, but they don't count against the number of artificer spells you prepare.

Create Explosives

You've learned how to quickly produce explosives. With tinker's tools or woodcarver's tools in hand, you can magically create three bombs or three sticks of dynamite (page 267-268 of the Dungeon Master's Guide) in an unoccupied space within 5 feet of you. This creation requires 1 hour of uninterrupted work, which can coincide with a short or long rest. Bombs and sticks of dynamite you create with this process use your spell save DC (instead of the normal DC of 12) for the dexterity saving throw, and are magical for the sake of overcoming damage resistances and immunities. Once you use this feature, you can't use it again for the next 24 hours or until you use an action to expend a spell slot to create and additional bomb or stick of dynamite.

Increased Destruction

At 5th level, you've learned how to increase the destructive capabilities of certain spells you cast and explosives you create. You can reroll a 1 on any of the damage dice of a bomb or stick of dynamite you make using your Create Explosives feature or spell you cast that deals bludgeoning, fire, force, radiant, or thunder damage. You must use the new roll.

Remote Detonate

At 9th level, you've learned how to cause your explosives to detonate from a distance:

-When you throw a bomb, stick of dynamite, or grenade, you can throw it up to 80 feet.

-When you create a bomb or stick of dynamite using your Create Explosives feature, you can make a detonator for each bomb or stick of dynamite you create. If you are within 120 feet of a bomb or stick of dynamite for which you have a detonator, you can use a bonus action to press the detonator, causing the bomb or stick of dynamite to instantly explode.

Explosives Master

At 15th level, you have been around explosives so frequently that they pose little threat to you, as well as you have learned how to maximize their destructive capabilities:

-You gain resistance to bludgeoning, fire, and thunder damage.

-Bombs and sticks of dynamite you make using your Create Explosives feature deal and additional 2d6 damage of their corresponding damage type.

-Bombs and sticks of dynamite you make using your Create Explosives feature deal double damage to objects and structures.
