Lumbrik Class for The Black Hack

For use with The Black Hack

Plagued by dreams of mechanized humanoids descending into green cracks in the Earth is what originally inspired me to create the Lumbrik class for DnD 5e. I liked the idea of robotic or robotic adjacent heroes in a fantasy setting but I found the Warforged of Eberron to be a little mechanically bland – I suppose without the context of Eberron they just feel like any other race in DnD 5e to me. Due to the incessant violent coughs and ejection of blood from my throat caused by contact with Dungeons & Dragons – yes, I know I should have it looked at – I decided to port over my custom class to The Black Hack so that I could use it again.

The Lumbrik are actually a worm-like species that are about the size of a human forearm. They live in underground tunnel networks as small groups who feed on the knowledge contained in the DNA of organisms. In an effort to gain more knowledge they designed mechanized suits that would interface with them called Exoframes. This allowed them to travel the surface of the world to consume more knowledge. You can find the untested custom class below. If you like the look of this, have suggestions, or a play report then let me know below. Enjoy!

Starting Stats

Starting Hit Points (HP) : roll 1d4 + 8
Starting Hit Dice (HD) : 1d10
Usable Weapons & Armour : None
Attack Damage : 1d4 unarmed, counts as a Large Weapon

D6Exoframe Insignia
1A purple worm bursting out of the ground
2Bold, flaming text that reads: “Global Worming”
3A lantern overflowing with glow worms
4A raven with worms for eyes
5A large, open book with indecipherable text on it
6A worm with a throbbing and disproportionately large brain


Every Lumbrik starts with a special ‘Crank’ function as described below. Also choose to start the game with either A or B:

  • A – 2d8 coins and purse, built-in large shield (+1 Armour Die), a shopping list of exotic fruits and vegetables
  • B – 2d8 coins and purse, built-in one-handed weapon instead of one arm (Replaces Attack Damage with 1d6), a kill order with a body quota

Hardened Frame

The Exoframe is made of hard metals and provides protection from attacks (AV2). Also when rolling Broken Armour Die a Lumbrik rolls with Advantage.


Due to your familiarity with the world underneath you do not suffer from Panic! due to a lack of light. However, an abundance of flashing lights may cause you to Panic!


Each Exoframe is constructed with a unique mechanical function that requires cranking for use. For every Action spent cranking increase the Usage Die for the given crank function up to a maximum of Ud12. In addition to downgrading the Usage Die when a 1 is rolled, you also lose 1 HP.

Function NameFunction Effect
LightYour Exoframe sheds bright light from a glass bulb with thick copper wire in it to allow Nearby creatures to see. This light lasts until the Usage Die has been depleted.
StompTwo large hammers extend out from your Exoframe and begin hammering on the ground around you. A number of creatures equal to your that are Nearby become Stuck. Attribute Tests to remove this Hindrance are made with an additional die equal to the Usage Die used for this. This occurs immediately after the cranking actions have finished after which the Usage Die is depleted.
MagnetA large chunk of metal in your Exoframe begins to rapidly spin. A number of metal items equal to the rolled value of the Usage Die are violently attached to your frame. When the Usage Die has been depleted, every attached item is then violently ejected outwards dealing 1 HP of damage to a number of Nearby creatures equal to the number of items ejected.
ShieldA large sheet of metal erupts from your Exoframe and rests into the ground after the cranking actions have finished. It provides cover for all Close creatures that stand behind it. While standing behind this, a creature has access to a shared pool of Armour Dice equal to the highest face value of the Usage Die. This effect can be stopped with an action after which the shield retracts itself into the Exoframe.

When You Gain a New Level

Acquire and share a number of Experiences equal to your current HD to advance a Level. When you gain a Level:

  • Roll a d20 once for each Attribute – if you roll over, it goes up one point, make an extra roll for one Attribute of your choice.
  • Gain 1HD – Roll 1d10 – gain that many additional maximum HP
