Tools of the Trade

Beginning at 1st level, you have developed a way to utilize blackpowder to create small Explosives that are an effective means of combat. You are proficient with Explosives, which are complex ranged weapons that weigh 1/2 pound and have the thrown property with a range of 20/60. On a hit, the Explosive deals 2d6 fire damage. Hit or miss, each creature within 5 feet of the target, including the target, must succeed on a Dexterity saving throw or take 2d4 piercing damage from the shrapnel. The DC for the saving throw equals 8 + your wisdom modifier + your proficiency bonus.
You must spend at least 30 minutes during a rest to make an amount of Explosives equal to your class level's designated amount using alchemist’s supplies and your Explosive kit, which is a leather box containing the specialized ingredients that you have perfected through your studies.
The Explosives lose potency after 24 hours, due to the different components settling, but storing them inside your Rune Space solves this problem, as the timeless nature of pocket dimensions slows any eventual breakdown of ingredients to a halt. The fire and piercing damage of the Explosives, as well as the number of Explosives you can make during a long rest, increase as you gain demolitionist levels, as shown on the Damage and Explosives columns of the Demolitionist table above.

Rune Hands

At 1st level, the palms of your hands up to your fingers are engraved with specialized, tattoo-like magic runes, enabling you to send Explosive bombs, similar destructive equipment, and small to medium items to your own personal pocket dimension. This includes the Explosive kit and alchemist's supplies, commonly called Rune Space, and from there, summon them directly to your hands. The process of transferring Explosives to and from the Rune Space takes 1 action during combat.
Due to the magic nature of the runes on your hands, you can remotely activate any Explosive you've Imbued (IM) with rune magic. The amount of Explosives you can Imbue increase as you gain demolitionist levels, as shown on the Explosives column of the Demolitionist table above.
How, where and when you received these runes are up to you and your DM.

Controlled Blast

Also at 1st level, you know how to place small Explosives in such a way that you can manipulate the environment around you without causing too much calamity. You can spend 5 minutes to study an object or area of an object no larger than 1 foot on any side (a lock on a door, the lid of a small chest, a set of bars on a window, etc.), granting you insight into the weak points of that object or area. You can then use one of your smaller Explosives to destroy that object or area of an object without causing any damage to surrounding objects or creatures.
The small Explosives used for this feature does not count against the number of Explosives you can normally make. You can use this feature twice, regaining any expended uses when you finish a short or long rest.
At 6th, 11th and 15th levels, choose an additional Controlled Blast feature from the list detailed at the end of the class features section.

Versatile Explosive

by 2nd level, you learn ways to modify the way you craft your Explosives, giving them special properties. Choose an option from the list detailed at the end of the class features section. When you craft Explosives during a long rest, you can choose to substitute your normal materials for the options you have chosen.
A single Explosive can only be affected by one modification at a time. If you choose to use a modification, you can make that modification for up to half of the Explosives crafted during that long rest.
You gain a new option when you reach 6th level, and again at 10th and 14th level. When you gain a level in this class, you can also replace an option you have with a different one.

Duck and Cover

Also at 2nd level, your time around your own Explosives has made you adept at knowing when and how to avoid getting hurt by the blasts. When you are subjected to a saving throw by the effect of one of your explosives, you can choose to automatically succeed on the saving throw, and if you do, you take no damage if you would normally take half damage on a successful save.

 

Runic Font

At 3rd level, you adopt a particular style of your trade that more closely defines the way you handle combat. Choose Font of the spellslinger, Font of the Alchemist or Font of the Engineer, each of which are detailed at the end of this class description. The spec you choose grants you features at 3rd level and again at 7th, 11th, and 15th level.
Disclaimer: The subclass you chose will drastically effect your Role Playing experience. The subclass you wish to use should be considered in  Character Creation.

Smoke Bomb

Also at 3rd level, you learn how to use spare components from your Explosive kit to create devices which utilize thick smoke and are effective at causing distractions, allowing you to make a quick getaway. You can make two of these devices when you make Explosives during a long rest, or by spending at least 10 minutes during a short rest. You can only have two Smoke Bombs crafted at a time, but when crafted during a long rest, they do not count against the number of Explosives you can normally make.
You can throw down a smoke bomb as a bonus action. when thrown, a smoke bomb creates an area of thick smoke in a 10-foot radius sphere that spreads around corners and lasts for 1 minute, or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it.. The area the smoke covers is heavily obscured and all creatures affected by it make all mundane ranged attacks at disadvantage.

Ability Score Improvement

When you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal you can't increase an ability score above 20 using this feature. (Optional Rule: your passive perception increases by 1)

Extra Action

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

Flashbang

Also at 5th level, you gain the ability to create special Explosives that produce a small blast of light and sound. You can create one of these Explosives when you craft Explosives during a long rest, or by spending at least 10 minutes during a short rest. When crafted during a long rest, a flashbang does not count against the number of Explosives you can normally make. Only 1 Flashbang can be made at a time, due to the flashbang being made of spare components.
You can use a flashbang as a reaction when you are targeted by an attack from a creature within 30 feet of you. When you use a flashbang, make a ranged weapon attack, as you would with any Explosive. On a hit, the creature has disadvantage on the triggering attack roll. Hit or miss, the target and any creatures within 5 feet of the target must succeed on a Constitution saving throw. On a failed save, a creature is blinded and deafened until the start of its next turn. The explosion also creates a loud bang that can be heard from 300 unhindered feet away. You must have a free hand in order to use a flashbang.
  The number of flashbangs you can make increases at 9th level, and again at 13th and 17th level, as shown on the Demolitionist table.

Master Dungeoneer

By 18th level, you have become so experienced in the ways of tactical layout and architecture that you gain proficiency in Perception. if you are already proficient in Perception then your proficiency bonus is doubled.

Demolitions Expert

By 20th level, you have perfected your art, in both efficiency and effectiveness. You can spend 30 minutes during a short or long rest to create Explosives. You can also use a Versatile Explosive option on any number of Explosives you make.
Additionally, you can use your Controlled Blast features an unlimited number of times, so long as you have one Explosive per use of Demolition Blast, use of Directional Blast, use of Propelled Blast, and per cubic yard of material for a use of Controlled Blast.

 

Versatile Explosive Options

---

Aerodynamic Explosive. This streamlined casing increases the range of the Explosive to 30/120.

Incendiary Explosive. This flammable powder doesn’t cause shrapnel to spread or cause damage on a hit, but it creates a fire within a 10-foot space that lasts for 1 minute. A creature that enters the fire or ends its turn there must make a Dexterity saving throw, taking the Explosive’s normal fire damage on a failed save, or half as much damage on a successful one.

Light Explosive. This lighter casing is easier to throw, allowing you to throw Explosives made with it as a bonus action.

Potent Explosive. This powerful component increases the damage dice of Explosives made using it from d6s to d8s.

Sticky Explosive. This adhesive causes an Explosive to stick to the target. Explosives made with this component don’t cause shrapnel to spread around the target, but you roll double the damage dice for the fire damage on a hit.

Controlled Blast Options

When given the opportunity to choose an additional Controlled Blast Option choose from the list below.

---

Controlled Blast: Demolition Charge. You have learned to utilize explosive material in a way that allows for stacks of material to be bound together for larger and more damaging explosions.
This Charge is best used for structural collapse of buildings and structures, or as a means to block of exits and break through walls. This Charge can also be used in combat and in unison with the Sticky Versatile Explosive Option. If used in combat, on a direct hit, the Explosive deals 4d6 force damage. Hit or miss, every creature within 15ft of the target, including the target, is pushed 5ft back and must succeed on a Dex save or take an additional 3d4 force damage. The DC for the saving throw is (8+proficiency+Wis)
if used for structural Demolition, the Charge will make a rough, 4x4 foot opening through 5ft of wooden wall, a 3x3 foot opening through 4ft of brick, a 2x2 foot opening through 3ft of iron, and will have no affect on magical barriers or solid stone unless stated otherwise by the DM.
The Charge can also completely disrupt the structural integrity of a 5x5 foot beam or pillar of wood, a 4x4 foot beam or pillar of iron, a 2x2 ft beam or pillar of solid stone, and will have no affect on magical structures unless stated otherwise by the DM.
The Charge takes up 2 Explosives spots of your current class level's maximum Explosives you can carry. i.e. 8 Explosives, no Charge. 6 Explosives, 1 Charge. 4 Explosives, 2 Charges. You can make two of these devices when you make Explosives during a long rest, or by spending at least 10 minutes during a short rest. You can only have two of these Charges made at a time.

Controlled Blast: Directional Charge. you have used your extensive knowledge of Explosives and your experience with traps to create an "Intruder Deterrence Device" or as it's more commonly referred to as, a Booby Trap.
This Charge is used primarily for surprising an intruder or foe, or as an early warning system, however it can be used in combat. you can craft one of these Charges during a long rest, or by spending at least 10 minutes during a short rest. You can only have one of these Charges made at a time. The number of Charges you can have at a time increases to two at 12th level. The Charge takes up 2 Explosives spots of your current class level's maximum Explosives you can carry. i.e. 8 Explosives, no Charge. 6 Explosives, 1 Charge. 4 Explosives, 2 Charges. The Charge, if used in combat, takes one action to set up and one to activate. Once positioned facing a direction, the Charge can't be repositioned without using an additional action.
Once the Charge has been activated, all creatures within a 10ft cone must make a Dex save or take 5d8 piercing damage. The save DC equals (8+Prof+Int)

Controlled Blast: Propelled Charge. Through your experiments with different Explosives and your familiarity with combat, you have discovered a way to attach small, controlled explosives to a weapon with the "thrown" property. You can use this feature twice. You regain your uses of this feature after completing a long rest. This feature can be used in combat but can be used outside of combat also.
In combat, you take an action to use one of your explosives and use the components to make up to two smaller explosives an secure them to a weapon with the "thrown" property, i.e. Daggers, Tridents, and javelins. Only one miniature explosive can be secured to a weapon at a time. if a weapon that has a miniature explosive secured to it hits a creature, that creature takes an additional 2d4 fire damage and 1d4 force damage.
