Arcane Mechanik[edit]

Wiping the grease from their hands, a young and lively gnome pulls up his safety goggles admiring a newly designed engine. This will help provide power for their larger projects. Another worker gets to work practicing a new spell out her notebook to help her get things done around the workshop. While they are Masters of the mechanical world, these seldom few will draw strength and knowledge from the arcane powers around them to improve their constructs and designs. Some work hard and make a goal out of unleashing the magic surrounding ordinary objects. Others see magic as a complex system using tools to study arcane power. No matter what, they are always crafting be it mechanical, like guns and robots, or magical, like arcane grenades.

Creating an Arcane Mechanik[edit]

Fighting Style[edit]

At 1st level, you adopt a style of fighting as your specialty. Choose one of the following options. You can’t take a Fighting Style option more than once, even if you later get to choose again.

  • Close Quarters Shooter - When making a ranged attack while you are within 5 feet of a hostile creature, you do not have disadvantage on the attack roll. You have a +1 bonus to attack rolls on ranged attacks.
  • Defense - While you are wearing armor, you gain a +1 bonus to AC.
  • Dueling - When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.
  • Great Weapon Fighting - When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll. The weapon must have the two-handed or versatile property for you to gain this benefit.
  • Interception - When a creature you can see hits a target that is within 5 feet of you with an attack, you can use your reaction to reduce the damage the target takes by 1d10 + your proficiency bonus (to a minimum of 0 damage). You must be wielding a melee weapon or shield to use this reaction.

Percussive Maintenance[edit]

At 1st level, you can fix gadgets by hitting it until it works. When striking a broken construct or gadget, it will work for a number of minutes equal to you Strength modifier plus your Intelligence Modifier. You can use this equal to the amount of levels you have in the Arcane Mechanik class. These uses reset at dawn.


Starting at 2nd level, you have an on going report of things that work and things that don't. When succeeding on repairing or building a new device, you record it in your notebook to remake later on. To recall from the notebook you must succeed an Intelligence check DC 10. If you pass, given you have the materials and tools required, it will take you 1d4 hours to build.

Spell Casting[edit]

You can keep a list of the spells you know in your handy-dandy notebook just like those fancy wizards do. At 2nd level, you have a notebook containing 3 1st-level spells of your choice. For every level up after level 2, you can learn a new spell off of the Artificer spell chart.

Construct Helpers[edit]

Starting at 2nd level, you have a few gizmos that whir around helping you and your allies. Choose 3 from the following:

  • Shield Friend - Adds +1 to the AC of whoever is closest to it.
  • Helping Hand - Assists you in completing a task. Whenever combat begins, you have advantage on the first attack you make.
  • Reloader - Reloads weapons for the closest ally. (DC 10 dexterity check)
  • Grappler - Wrestles the nearest enemy to the ground. (DC 15 strength check to break free)
  • Scout - Quickly moves ahead of the party to relay through signals and beeps what it sees.
  • Searcher - Makes investigation checks to find hidden items and loot (Investigation is equal to yours)

These helpers requires batteries to operate; one battery will give them 1d20+4 hours of juice. During a short rest you can reassemble one to change their role. There can be multiple of the same style deployed at once.

Subclass Feature[edit]

At 3rd level, you chose an Archetype. Choose between Armorer, Battlesmith, Tinkerer, or Gunner. They are detailed at the end of the class description. Your choice grants you features at 3rd level and again at 7th, 10th, 15th, and 18th levels.


At 4th level, your Constructs will come to your aid if you fall during combat. If all your devices are active and next to you, you have advantage on your death saving throws.

Ability Score Improvement[edit]

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.

Extra Attack[edit]

Beginning at 5th Level, you can Attack twice, instead of once, whenever you take the Attack action on Your Turn. The number of attacks increases to 3 at 12th level and 4 at 19th level.

Turret Builder[edit]

At 6th level, you can build a tall, destructive turret to aid you in a fight. You can set up the turret as an action. When manning the turret, you make a ranged weapon attack. On a hit, the turret deals 1d10 piercing damage. (Range 50/200) The turret must be reloaded after 3 shots.

Improved Lifeline[edit]

At 9th level, if all your devices are active and next to a downed ally, they also have advantage on death saving throws; the constructs will always help you first.

Advanced Turret[edit]

Starting at 11th level, your turret can specialize in a variety of attack styles. Choose an option from the list bellow:

  • Sniper rounds - 1d12 piercing (100/400)
  • Mini cannon balls - 2d8 bludgeoning (15/60)
  • Saw blades - 2d6 slashing (60/240)
  • Flamethrower - 2d10 fire (30/120) - On a hit, they make a Con save (DC is your spell save DC). If they fail they take 1d6 fire damage for an amount of rounds equal to your intelligence modifier (minimum of 1).
  • Pressurized water - 3d4 Force (30/120) - On a hit, they make a Str save (DC is your spell save DC). If they fail, they are knocked prone and pushed 10 feet back.

At the end of a long rest, you can change the turret type.
