Oath of Nail Und Hammer

"Will you join me… in the great task to purify the abominable filth?"
- Kromer, The One Who Grips of the Nail Und Hammer Inquisition


The Nail Und Hammer Inquisition Is a group that works to 'Purge' or 'Cleanse' the world of that which is not human, however, they have recently expanded to allow Elves, Dwarves, and other Humanoids to join their ranks, both to increase the number of members, and so other humanoids can save themselves from being Purged, if their devotion is strong enough, that is.
Paladins who swear the Oath of Nail Und Hammer devote themselves to rooting out corruption wherever it is found. To them, pain is purification, conviction is salvation, and mercy toward the impure is the greatest sin of all.
 ... Or they were Frightened into joining by threat of Execution.

Tenets of the Nail Und Hammer
Thought the Exact words vary between Inquisition groups, the strictures are almost the Exact same:

Purity. Humanity is sacred. Reject the corruption of machinery, mutation, and unnatural flesh wherever it is found.

Pain. Suffering tempers the soul. Accept pain willingly, for only through hardship can one achieve true purity.

Authority. The Scriptures admit no compromise. Obey those who bear the Nail and Hammer, for doubt is the first step toward heresy.

Purge. Strike down the impure without hesitation. Mercy shown to corruption is cruelty shown to mankind.

Großhammer - Level 7

"It is the time of purification… the hour for us to remove filth from the soil of purity."
 - Kromer, The One Who Grips.

Aura of Fanaticism
Starting at 7th level, You and friendly creatures within 15 feet of you cannot be charmed. Additionally, while within the aura, creatures ignore the effects of exhaustion, though they still accumulate levels of exhaustion normally. Creatures affected by this aura deal additional radiant damage equal to the target's Nails stacks whenever they hit it with a melee weapon attack. A creature can benefit from this additional damage a number of times on each of its turns equal to its proficiency bonus.
At 18th level, the range of this aura increases to 40 feet.

Cleanse Sin
Starting at 7th level, When a melee weapon attack you make deals damage, compare all weapon damage dice rolled for the attack, if 2 numbers are the same, the creature is inflicted with 1 "Nails" stack. Creatures affected by your 'Purge Prostheses' Passive are also inflicted with a stack of Nails if any 2 numbers on the damage dice are either both even or both odd. A creature can only be inflicted with 1 Nails stack per attack.
 - If the attack rolls only one weapon damage die, roll an additional 1d4. This die is used only to determine whether Nails are inflicted and does not deal damage.

A creature with Nails takes Radiant damage equal to 2x the Nails stack at the start of each of their turns, and their movement speed is reduced by 5 feet per stack.
 - Nails have a maximum stack of 10.
 - If the creature's movement speed would be reduced to 0, they are forced into Prone, and cannot stand up until their movement speed is increased above 0.
 - A creature with Nails can spend a bonus action to make a constitution saving throw against your Spell Save DC, on a failure, they take damage equal to 2x their Nails stack. On a success, they lose half of their Nails stack.
 - If the Nailed creature is forced prone, they have Disadvantage on any attempt to remove Nails.
 - A separate creature can attempt a Wisdom (Medicine) check against your Spell Save DC to remove Nails from the creature, On a failure, the Nailed Creature takes radiant damage equal to twice their Nails stacks. On a success, the target loses half of its Nails stacks (rounded down).
 - If a creature is prone due to Nails and has no allied creatures capable of removing its Nails, it can use a bonus action to violently tear them free. It takes radiant damage equal to six times its current Nails stacks, removes all Nails from itself, and immediately stands up.

The One Who Shall Grip - Level 15

"What constitutes a human is flesh, blood… and bone. All else is filth… I can give that mask of yours a pass. It’s essentially a piece of clothing."
 - Kromer, said to Guido, A Hammer of the Nail Und Hammer Inquisition.


Such Filth!
Once per turn, when a creature misses you with an attack, you can use your reaction to cast "Dissonant Whispers", which does not consume a spell slot.
 - If the target would be affected by your 'Purge Prostheses' feature, they automatically fail the saving throw.

Self-Destructive Purge
