Dungeon 9 of 17 — added v253 · level 560 to enter
The Debtors' Deep
The only ammunition in this room is injury the boss has already dealt you — and playing flawlessly lands nothing at all
Eight axes were already claimed by the time this dungeon shipped: where you stand, when you strike, what you spend, what you can lose, how hard you hit, what you repeat, what you give up forever, and which instrument you use. The Debtors' Deep's boss, the Reckoner, claims a ninth: what it has already taken out of you.
The Ledger: damage you deal is damage you've already taken
The Reckoner keeps a ledger that starts at zero and is written by exactly one event: a point of the player's own health being lost. Each point taken is entered not as a raw number but as its share of the player's whole health bar — so stacking durability never makes settling the debt cheaper, the cost is scale-invariant by design. The player's blows can only land out of that balance:
landed = min(offered, ledger, what's left of the boss's health)
Every point of an offer beyond the current balance is overdraft — it lands exactly zero, and it isn't deferred, queued or banked for later. It's simply gone, the instant it's offered. An untouched player standing at range with the trigger held down can pour a million points of damage into the Reckoner and land nothing, forever, because a flawless run never opens an account to draw on. The only way to actually damage this boss is to let its 725-damage strike land on purpose, and pay for the privilege out of the one resource in the entire game whose exhaustion ends the run outright.
Why this is the opposite of the Arbiter's axis
Compare directly to The Parted Hold's Arbiter, the nearest claimed axis: the Arbiter's guard sheds by the mere passage of time with the trigger released, so a player who is never hit at all still collects the entire prize — their own health bar is never a currency in that fight at all. The Reckoner issues its allowance only out of injury it has personally inflicted, so that same flawless, never-hit player lands exactly zero here no matter how long they wait, how hard they hit, or how patiently they release the trigger. The correct play is to walk into a 725-damage hit on purpose — deliberately spending the resource whose exhaustion ends the run, a direction no claimed axis before this one had ever asked a player to move toward.
Measured live, four ways
| Behaviour | Damage offered | Result |
|---|---|---|
| Habitual (never take a hit, held trigger, best weapon) | 1,000,000 | Landed exactly 0; ledger stayed at exactly 0 |
| Overdraft (small balance, enormous offer) | — | Landed exactly the balance and not one point more; the overdraft is destroyed on the frame — a bigger weapon buys nothing |
| Played (injury taken, no debt stones cut) | — | Issues at the plain ×1.00 rate |
| Played well (three debt stones cut first) | — | The same injury issues at ×2.00 — same boss, same weapon, same wounds, double the exchange |
The three debt stones: paid in the same currency
Three debt stones stand on a ring, and each pays a Gold Bar, cash and experience the instant it's cut, kept whatever happens next. Cutting a stone raises only the rate a point of the player's own blood is entered into the ledger at — never the player's damage, and never the boss's health directly. Notably, a debt stone won't even acknowledge a player standing at full health: the player has to be bleeding — at or under half maximum health — before a stone will cut a mark at all, so even the sub-goals in this room are bought with the same currency as the boss fight itself.
Balance
The Reckoner is an existing enemy template with its stats overwritten on that one spawned instance, so no save's bestiary completion count ever moves. Its damage was set to 95 — identical to the eight bosses before it. Its own ordinary kill reward is zeroed out entirely, so every unit of value in the room passes through either a debt stone or the reckoning payout itself, keeping the measured numbers above exact. Its health pool was reduced substantially in later balance passes, from 118,444 originally down to 29,479 at the Boss Pass (v363) — see the axis dungeons overview for the shared balance history behind all seventeen doors.
How it's found
A cairn of tally-sticks marks the entrance — deliberately unlike any of the eight dungeon markers before it. Found by the same three signposts every keyless dungeon in the series relies on: the structure itself, a one-time toast within 500 metres, and a bearing-and-range line on the idle prompt within 900 metres.
Version history
- v253 — added. Ships as the ninth dungeon and ninth boss, claiming the axis of prior injury as the only valid currency for damage — the first fight in the game where the player's own health bar doubles as ammunition. The next dungeon, The Stilled Assize (v254), claimed a tenth axis in turn.
- v255 — a missing weapon-fire handler fixed. v253 had shipped without a dedicated [F]-key arm inside the Deep, so firing a weapon while holding anything other than a weapon fell all the way through to the game's ordinary harvesting code instead of failing gracefully. Fixed in exactly the shape every other dungeon around it already used; nothing else about the Deep was touched.
- v362 — level requirement lowered from 2,250 to 560, part of the game-wide compression of all seventeen axis dungeon doors into the early game.
- v363 — boss health rebalanced from 118,444 down to 29,479, and its displayed nameplate number changed from a deterministic 2,860 to a deterministic 691, as part of the Boss Pass that made every dungeon's boss survivable at the level its own door actually admits.
Trivia
- Settling the Reckoner's account entirely at the base rate costs roughly 2.96 whole health bars' worth of injury by the game's own math — dropping to about 1.48 whole bars at the maximum ×2.00 rate from cutting all three debt stones first.
- Is one of seventeen axis dungeons on Earth. Alone among the first nine, it's the only fight where the player's own health bar is simultaneously the resource being spent and the thing that ends the run if it empties.
