The Bombardier is for those Artificers who believe that "subtlety" is just another word for "boring." Why cast a spell when you can throw a bomb? Why solve a problem when you can blow it up? These explosive enthusiasts take tinkering to dangerous new levels, crafting all manner of magical explosives—from acid-spewing grenades to improvised explosives made out of a bag of holding—just to watch things go boom. As they advance, they get even more obnoxiously creative, combining and modifying their bombs with chaotic flair. If it explodes, sets something on fire, or otherwise causes destruction and chaos they’ll find a way to make it happen, all while calling it "art."

Bombardiers tend to be the kind of people who think "restraint" is for amateurs. With an inflated sense of ingenuity, a slew of personality disorders, and "necessary" casualties in the thousands, they’ll gleefully insist that no situation exists that can’t be solved by a well-timed detonation. Whether they’re thrill-seekers itching for the next explosion or aloof "geniuses" who smugly overcomplicate everything, Bombardiers often leave their companions wondering if they’re brilliant—or just plain reckless. Either way, you’ll hear them coming.

Bomber

3rd-level Bombardier feature

When you choose this subclass, you learn to make specialized explosives that take advantage of your magical and mechanical expertise. 

Bombs. You learn to create three explosive of your choice, which are detailed under Explosives below. You can store a number of bombs up to your proficiency bonus. When you create a new bomb, if you do not have the capacity to store it, you must deconstruct one bomb of your choice. While other creatures may use your bombs (see Using a Bomb), they may not store them and all unexploded bombs you create count against your storage capacity. All Explosives contain the following information: minimum level, thrown range (short/long), activation time, area of effect (typically a sphere), damage type, a description, any other effects, and the effects of increasing the bomb's level.

Your list of potential explosives increases and you learn two additional bombs of your choice at 5th, 9th, 13th, and 17th level. Each time you learn new Explosives, you can also replace one Explosive you know with a different one.

Making Bombs. Creating a bomb requires 10 minutes and tinkerer's tools, which may be part of a short or long rest. You may create a number of bombs up to your proficiency bonus and regain the ability to do so when you start a long rest. If the level of the Explosive can be increased, you must choose its level when you create it. Its level cannot exceed the maximum level of artificer spells that you can cast. You may create additional bombs by expending a spell slot; the level of spell slot required is equal to the level of the bomb. All other conditions must be met.

Decoy Charge. This "bomb" can mimic the appearance of any other type of Explosive that you know. It functions as if it was a bomb of that type (including activation time and thrown range) with a level of 0; however it cannot be detonated. A successful Intelligence (Investigation) check against your spell save DC will reveal it as a Decoy Charge. You may create and store a number of Decoy Charges equal to your Proficiency Bonus and regain all uses on a Short or Long Rest. Decoy Charges do not count against your  For each Decoy Charge made in excess of your storage capacity, you must deactivate another Decoy Charge.

Using a Bomb. All bombs are activated upon impact with a target point within the short thrown range. You may choose a target point beyond the short range (but less than the long range) at the risk of a Premature Explosion. Most bombs require an action to throw a bomb; however the exact time is specified in the Explosive's description. Other creatures may attempt to use your bombs using the short range, but are subject to a Premature Explosion.

Premature Explosion. When subject to a Premature Explosion (see Using a Bomb), the creature using the bomb must make an Intelligence or Wisdom check with a DC of 10 plus the bomb's level. If it fails the check, the bomb detonates early at a point within the short range. The DM rolls 1d20 to determine where the bomb explodes, exploding in the user's hand on a 1 and increasing by 5 feet for each number (e.g., 5 feet for 2 and 20 feet for 5) to a maximum of the short range.

Saving Throws. Many of your Explosives require your target to make a saving throw to resist the bomb’s effects. The saving throw DC is equal to your spell save DC.

Bombard Spells

Bomb Surgeon

5th-level Bombardier feature

You've risen from unhinged amateur arsonist to a maestro of the explosive arts. With your newfound "precision", you learn to combine bombs to increase their power, range, or just make things a little crazier. As a bonus action, you can combine your bombs in the following ways:

• Higher Yield: You combine two or more bombs of the same type, the level of the bomb increases to the level of the device, to a maximum of 5.
• Greater Blast Radius: You combine two or more bombs of the same type and level, the area of effect of the bomb increases by 5 feet for the level of bomb (e.g., combining two level 2 bombs would act as a level 2 bomb with an additional 10-foot radius). If you combine three bombs, the area of effect increases by an additional 10 feet (e.g., combining three level 3 bombs would act as a level 3 bomb with an additional 25-foot radius). The area of effect type (e.g., sphere, cube, cone) remains the same.
• Multi-purpose: You combine two or more bombs of different types. When the combined device is detonated, all component bombs detonate simultaneously.

You can combine no more than two bombs into a single device, which has a level equal to the total level of all combined bombs. Each bomb in the device still count against your storage capacity. The combined bomb can have a level no higher than than twice your proficiency bonus. You can dismantle a device into its component by spending 10 minutes with your tinkerer's tools as if you were making a bomb.

At level 9, the number of bombs you can combine increases to 3.

Powder Mage

5th-level Bombardier feature

You don't always have time to make a bomb, especially if you run out in the middle of a fight. You've learned to use your magic to emulate one of your explosives. As a bonus action, you can expend a spell slot to create a bomb of an explosive type that you know. You must immediately use your action to throw the bomb and make a Premature Explosion check. The bomb can only be thrown at short range. The spell slot expended must be at least one level higher than the level of the bomb, which is created at its minimum level. These magically created bombs cannot be combined with other explosives and must be detonated on impact.

Dungeon Crawler

5th-level Bombardier feature

Cowards! Only the craven would create a trap rather than throw a bomb. Your experience allows you to easily find and disarm such cowardly displays. When you cast the find traps spell, it reveals the location of all traps that are not behind total cover, including natural weaknesses and traps. If you cast the spell at level 3, you also identify traps behind total cover and learn the nature of traps not behind total cover. At level 4, you learn the types of all traps in range and can add your intelligence modifier to any skill check made to try to disarm a trap not behind total cover. At level 5, you automatically succeed on any skill check made to disarm a trap.

Four Fingers

5th-level Bombardier feature

Unlike your colleagues, you've somehow managed to survive long enough to gain experience around regular explosions. While you may be a few fingers or limbs down, you are more resilient in the face of potentially deadly explosions. You have have advantage on saving throws against bombs and resistance to damage from them.

Demolitionist

9th-level Bombardier feature

You've finally learned how to change the trigger mechanisms for your bombs. I thought you were supposed to be smart, but you're nine levels into this and just figuring it out now? When you create a bomb, you also choose one of five trigger mechanisms. You may also change the trigger mechanism as a bonus action. The trigger mechanisms are described below:

• Impact Detonation (default): These bombs explode on impact when thrown. This is the default choice for all explosives.
• Remote Trigger: You can place one of these bombs or throw it at the cost of its activation time; however, they do not detonate on impact. They can be detonated remotely using an action or bonus action. You must be within 200 feet of the bomb to trigger it in this way.
• Proximity Detonation: You can arm and place one of these bombs or throw it at the cost of its activation time. These bombs detonate on impact (if thrown), when a creature moves within 5 feet of them, and when damaged. These bombs are immune to Psychic, Poison, Necrotic, and Radiant damage, resistance to all other damage types, and immune to all conditions. They have an armor class of 15 plus the level of the bomb.
• Dead-man's Switch: These bombs can be armed or disarmed with a bonus action and require a free hand. If your hand releases the detonator, either willingly or unwillingly (e.g., becoming incapacitated), the bomb detonates. 
• Directional Charge: You can place one of these bombs or throw it at the cost of its activation time. These bombs detonate on impact (if thrown), remotely with an action or bonus action, and when damaged. These bombs are immune to Psychic, Poison, Necrotic, and Radiant damage, resistance to all other damage types, and immune to all conditions. They have an armor class of 15 plus the level of the bomb. If this bomb is placed, you must choose its direction and its area of effect becomes a cone and is increased by a number of feet based on its level, as shown in the table below. If a bomb with a directional charge is thrown, the direction is chosen at random by rolling 1d8.

Bomb Levels	Increased Radius
1-3	5 feet
4-6	10 feet
7-9	15 feet
10-12	20 feet

 

Any creature may use an action to attempt to disarm an undetonated bomb in their space by making a Dexterity (Sleight of Hand) skill check. The difficulty is equal to 10 plus the level of the bomb. On a failure, they must roll for a Premature Explosion. The DM may require an Intelligence (Investigation) or Wisdom (Perception) check to determine the method to disarm the bomb or detect a concealed bomb. You have advantage on attempts to disarm bombs you created.

Steady Hands

9th-level Bombardier feature

You're still alive? I had 10,000 GP on you blowing your guts all of your friends by level 7... Your hands are rock steady and you're always ready to move. When you’re subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw and only half damage if you fail. You can’t use this feature if you have the Incapacitated condition.

Master Crawler

9th-level Bombardier feature

They may be cowards, but the trap makers have some good equipment. Whenever you successfully disarm a mechanical trap, you may keep the parts provided it is small and light enough for you to carry. You can use the parts recreate and arm the trap. The amount of time required to recreate the trap is determined by the DM, but takes no less than 1 minute.

Tempting Fate

15th-level Bombardier feature

Really? Really?! Either fate (cough Dungeon Master cough) has taken a liking to you or you're letting the rest of your party do the heavy lifting. As your ego grows, you can afford to take more risks. If damage would knock you unconscious, you may negate all damage and other conditions from that source. Once you use this ability, you must complete a long rest before doing so again.

Blastsmith

15th-level Bombardier feature

Recruiting new party members becomes challenging when they find out you blew up the previous ones. When one of your bombs detonates, you can choose a number of other creatures that you can see, up to your Intelligence modifier, to automatically succeed on all saving throws against it.
