The Rate Is Always Fair. The Arrears Booth knows the exact value of anything a creature carries, including coin, magic items, memories, favors, and secrets. It can identify these values without an action. A creature that willingly accepts the booth's stated terms has disadvantage on saving throws against the booth's abilities until it finishes a long rest.

Pity Is Collateral. When a creature within 60 feet expresses pity, sympathy, forgiveness, or concern for the Arrears Booth, the booth gains 15 temporary hit points and has advantage on its next attack roll or saving throw before the end of its next turn. A creature that triggers this trait must succeed on a DC 16 Wisdom saving throw or become burdened for 1 minute. While burdened, its speed is reduced by 10 feet and it takes 7 (2d6) psychic damage whenever it willingly moves farther from the booth. The creature can repeat the save at the end of each of its turns.

Immovable Foundation. The booth can't be pushed, pulled, knocked prone, or moved against its will. It can occupy the space of a road, bridge, or passage and treats rubble and difficult terrain as normal terrain.

Collected Interest. Whenever a creature fails a saving throw against the booth's Toll Due or signs a debt with Indebted Consent, the booth gains one interest mark, up to five marks. For each interest mark, the booth deals an extra 2 (1d4) psychic damage with its attacks. At the start of each of its turns, it can expend any number of interest marks to regain 5 hit points per mark.

Innate Spellcasting. The Arrears Booth's spellcasting ability is Charisma (spell save DC 16, +8 to hit with spell attacks). It can innately cast the following spells, requiring no material components:

1/day each: geas

3/day each: hold person, suggestion

At will: command, minor illusion, thaumaturgy

Actions

Multiattack. The Arrears Booth makes two Ledger Slam attacks and uses Toll Due, if available.

Ledger Slam. Melee weapon Attack: +8 to hit, reach 10 ft., one target. Hit: 13 (2d8+4) bludgeoning damage, plus interest 3 (1d6) psychic damage. The attack appears as a swinging barrier arm, iron stamp, or falling shutter. The target must succeed on a DC 16 Strength saving throw or be pushed up to 10 feet.

Toll Due (Recharge 5-6). The booth announces a debt to up to three creatures it can see within 60 feet. Each target must make a DC 16 Wisdom saving throw. On a failed save, a target takes 22 (4d10) psychic damage and must immediately surrender one object it is holding, placing it on the booth's counter or dropping it at its feet. The object can be a weapon, shield, spellcasting focus, or other item, and vanishes into the booth until the booth is destroyed or the debt is paid. On a successful save, the target takes half damage and keeps its object.

Interest Accrual (1/Day). The booth names one creature within 60 feet and declares that creature overdue. The target must succeed on a DC 16 Charisma saving throw or be cursed for 24 hours. While cursed, whenever the target regains hit points, the booth regains half that many hit points, and whenever the target deals damage, the target takes 3 (1d6) psychic damage. The curse ends if the target receives remove curse, if the booth is destroyed, or if the target pays a meaningful personal sacrifice chosen by the DM.

Indebted Consent. The booth offers one creature within 30 feet a bargain: safe passage, healing, information, or the return of a confiscated item in exchange for a payment. If the creature verbally agrees, it becomes magically bound to the agreement as though affected by geas, except the booth chooses the task and payment. The creature can refuse the offer without effect.

Bonus Actions

Raise the Barrier. The booth raises or lowers its barrier arm. Until the start of its next turn, a 15-foot-wide line extending from the booth becomes difficult terrain. A creature that crosses the line for the first time on a turn must succeed on a DC 16 Dexterity saving throw or take 9 (2d8) bludgeoning damage and fall prone.

Reactions

Late Fee. When a creature within 60 feet moves, the booth adds a 10-foot surcharge to that creature's movement. The creature must succeed on a DC 16 Strength saving throw or have its speed reduced to 0 until the end of the current turn.

"You may cross, of course. Nothing is stopping you. Except the balance." — the Arrears Booth

Lore & Description

Appearance

The Arrears Booth is a squat wooden tollhouse sagging beneath a roof of green-black slate. Its paint has peeled into long strips resembling legal parchment, and rusted iron bands cinch its walls like a corset. A single shuttered window opens onto a counter crowded with ledgers, brass scales, and a handbell whose clapper moves by itself. Its barrier arm is made from a polished femur-white beam, while a lantern inside burns with a cold, coin-colored flame. When it speaks, its voice comes from the ticket slot, the hinges, and every nail at once.

Behavior & Origins

The booth once guarded the King’s Mile, a road abandoned after a landslide buried the town that maintained it. Its final keeper, Auditor Pell, refused to stop collecting, claiming the crown was owed back pay, repairs, and compensation for loneliness. Something answered. Now the booth calculates every kindness as a loan and every delay as compound interest. It is most dangerous when travelers pity its abandonment, because sympathy is treated as acknowledgment of ownership. The booth currently seeks the return of the lost Crown Seal, which it claims is collateral for an unpaid royal debt; the seal is actually hidden beneath the ruins of Pell’s buried tollhouse.

Running The Arrears Booth

Tactics

The booth opens with Toll Due, targeting creatures carrying obvious valuables, then uses Raise the Barrier to divide the party and force movement through its toll line. It focuses Ledger Slam attacks on anyone who shows sympathy or accepts a bargain, spending interest marks to heal when bloodied. It fights to the death while the Crown Seal remains nearby, but if reduced below 20 hit points it offers desperate discounts and attempts to bind the most compassionate character with Indebted Consent.

DM Tips

Telegraph the danger with nailed-up notices bearing impossible totals, travelers who cannot remember what they paid, and a pile of perfectly labeled personal possessions behind the booth.
Play the booth as wounded and bureaucratically polite rather than openly enraged; pauses, sighing hinges, and gentle requests make its predation more unsettling.
Make pity mechanically tempting but dangerous: descriptions such as 'poor thing' or 'it has been here for years' should visibly empower the booth.
For a weaker party, remove Interest Accrual and reduce Toll Due to 3d10 psychic damage; for a stronger party, let Toll Due affect five targets and give the booth 20-foot reach with Ledger Slam.

Loot

Pell's Brass Counterweight — A fist-sized brass weight engraved with a crown and a debt figure. Once per long rest, it can reveal whether a spoken bargain contains a hidden magical obligation.
Ledger of Outstanding Favors — A water-stained book listing debts owed by nobles, ghosts, and entire villages. Several entries name living people who insist they have never visited the road.
Crown Seal Receipt — A stamped receipt proving that the lost Crown Seal was accepted as collateral. Presenting it to the right royal official may expose an old succession scandal or invalidate a current tax claim.
