Unpaid Account. When a creature touches the Red-Ink Auditor or willingly reads one of its pages, the Auditor records that creature's true name and marks it as an Account Holder for 24 hours. An Account Holder can't benefit from being invisible to the Auditor, and the Auditor always knows the direction and distance to it while it is within 1 mile. A creature can erase its name with a successful DC 14 Intelligence (Investigation) check made while using ink, ash, or blood to deface the page containing it.

Relocation Clause. When the Red-Ink Auditor is reduced to 0 hit points, its cover slams shut and its body vanishes. It reappears in an unoccupied space within 60 feet of the creature that dealt the final blow, or in the nearest unattended book, ledger, or written contract if no such space exists. It regains 15 hit points, and this trait can't be used again until 24 hours have passed. The Auditor's destruction is therefore temporary unless its binding clause is nullified.

Inkbound Existence. The Auditor doesn't need air, food, drink, or sleep. It can move through the space of another creature, though it can't end its movement there.

Actions

Multiattack. The Red-Ink Auditor makes two Quill Slash attacks, or it makes one Quill Slash attack and uses Audit Soul.

Quill Slash. Melee weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 7 (1d8+3) piercing damage, plus 3 (1d6) psychic damage. The Auditor tears a long red quill from its spine and lashes with it. If the target is an Account Holder, it must succeed on a DC 13 Wisdom saving throw or have disadvantage on its next saving throw before the end of its next turn.

Audit Soul. One creature the Auditor can see within 60 feet must make a DC 13 Charisma saving throw. On a failed save, the target takes 10 (3d6) psychic damage and becomes financially marked for 1 minute. While financially marked, the target's speed is reduced by 10 feet, and whenever it regains hit points, it regains half as many hit points, rounded down. The target can repeat the saving throw at the end of each of its turns, ending the effect on a success. On a successful save, the target takes half damage and suffers no other effect.

Issue Summons (Recharge 5-6). The Auditor opens to a page bearing a creature's name and invokes it. Up to three Account Holders within 60 feet must succeed on a DC 13 Strength saving throw or be pulled up to 20 feet toward the Auditor and have their speed reduced to 0 until the end of their next turn. A creature that fails this save also drops one object it is holding, chosen by the Auditor.

Bonus Actions

Turn the Page. The Red-Ink Auditor teleports up to 20 feet to an unoccupied space it can see, leaving behind a flutter of blank paper. This movement doesn't provoke opportunity attacks.

Reactions

Objection Filed. When a creature within 30 feet succeeds on a saving throw against the Auditor, the Auditor can force that creature to reroll the save. The creature must use the new roll. Once the Auditor uses this reaction, it can't use it again until the start of its next turn.

"Your soul is not confiscated. It is merely overdue." — The Red-Ink Auditor

Lore & Description

Appearance

The Red-Ink Auditor is a thick, iron-cornered tax ledger bound in cracked oxblood leather. Its pages turn without wind, covered in cramped columns of names, debts, dates, and tiny anatomical sketches. A silver quill sprouts from its spine like a rigid insect leg, dripping red ink that vanishes before it touches the ground. When it speaks, its cover opens to reveal no pages at all—only a narrow, whispering mouth between rows of moving script.

Behavior & Origins

The Auditor was commissioned by Magistrate Odran Vey to collect a soul-tax levied on every oath sworn in the city of Bellweather. When the magistrate died, the contract remained active, and the ledger developed a will of its own. It seeks anyone who has broken a promise, evaded a debt, or profited from another's loss, adding new clauses to its endless account. The Auditor can be permanently quieted only by finding Odran Vey's original contract in the sealed records beneath Bellweather's old customs house and striking the magistrate's name from it with the quill that now serves as the creature's weapon.

Running The Red-Ink Auditor

Tactics

The Auditor opens combat by marking the creature most likely to escape or heal, then uses Turn the Page to keep behind cover while attacking with Audit Soul. It uses Issue Summons to drag marked creatures into hazards or away from allies, and it employs Objection Filed against the strongest save of the round. When reduced to 0 hit points, it relocates rather than dies; it fights to the death only if an enemy carries Odran Vey's contract or threatens its original ledger page.

DM Tips

Telegraph danger with red names appearing in the ledger, ink crawling across nearby documents, and the sound of an unseen quill scratching whenever a character makes a promise.
Roleplay the Auditor as a fussy, merciless bureaucrat that never raises its voice; it cites imaginary statutes and offers technically valid but ruinous payment plans.
If the party is struggling, reduce Audit Soul's damage to 2d6 and remove the healing reduction from financially marked. For a stronger party, let Relocation Clause trigger every 12 hours instead of once per day.
Make Relocation Clause matter narratively: after the fight, the Auditor can reappear in a character's spellbook, a merchant's contract, or the party's own map.

Loot

Red-Thread Quill — The Auditor's quill can write on stone, skin, or air. Once per day, it can cast comprehend languages, but each use causes the writer's name to appear in an unknown ledger somewhere in the world.
Page of Outstanding Debts — A torn page lists three local names and the terrible things each has promised. Returning it to one named person can reveal a secret, earn an ally, or provoke a desperate enemy.
Iron Ledger Corner — A cold, rune-etched corner torn from the Auditor's binding. It is proof that the creature has been defeated, but not destroyed, and fits a lock beneath Bellweather's old customs house.
