Dungeons

The one-per-region boss run — nine encounters, the entry fee, boss modifiers, and its richer drops.

Every region has exactly one dungeon tile. Clearing it the first time opens the next region, so the dungeon is the gate on the world map. Each entry costs gold and runs a fixed nine-encounter gauntlet that ends on a boss. Drops inside are richer than open-world tiles, but no gold changes hands inside the run — see below.

This page is about the normal dungeon. A separate, far more expensive echoed dungeon exists — jump to Normal vs. echoed or the Echo Ascension page.

The nine-encounter run

A dungeon run is a fixed sequence of nine spawns — no early clears, no random length:

#	1	2	3	4	5	6	7	8	9
Rarity	Common	Common	Common	Common	Common	Rare	Rare	Rare	Boss

That is 5 common → 3 rare → 1 boss (the boss is a special-rarity enemy). Killing the boss on encounter 9 completes the run. The whole sequence uses the dungeon tile’s own difficulty rank for enemy level, so a higher-region dungeon spawns higher-level foes across all nine.

First clear must be earned in active play. Idle and offline progress can farm an already-cleared dungeon, but they can never first-clear one — the boss is held at the “approach” prompt until you click Start Fight. Close the game or leave mid-run and a first-clear attempt is abandoned.

Boss stat modifiers

The boss is a special enemy, so it first inherits the full special-rarity scaling, then the dungeon layer multiplies its combat stats on top. Both layers stack multiplicatively.

Special-rarity base (every boss and every open-world champion carries this):

Stat	Special multiplier
HP	×3
Damage	×1.6
Attack Rating	×1.4
Defense Rating	×1.4
XP reward	×4
Gold reward	×4 (not paid inside a dungeon — see below)
Drop-chance	×4
Resistance bonus	+0.06 flat

Dungeon boss layer (applied only to the encounter-9 boss, on top of the special base):

Stat	Boss multiplier	Effect
HP	×1.1	+10% health
Damage	×1.05	+5% hit
Attack Rating	×1.05	slightly better accuracy
Defense Rating	×1.05	slightly harder to hit
Attack interval	×0.94	attacks ~6% faster

So a dungeon boss’s effective HP is base × 3 × 1.1 = 3.3× a same-level common, and it swings on a base × 0.94 interval. There is no dungeon-specific XP or gold multiplier beyond the ×4 the special rarity already grants.

No gold inside the dungeon

Per-enemy gold is skipped for the entire run — every one of the nine kills, boss included, pays zero gold. The only gold a dungeon ever hands you is the one-time first-clear reward:

firstClearGold = 800 + difficultyRank × 40

On top of that, a first clear also grants a guaranteed rare gear reward (rolled from the region’s tier cap, 3 affixes) and a chunk of XP. Repeat clears give none of this — no gold, no guaranteed item — only whatever the nine kills drop plus a chance at a Scroll of Amnesia.

Entry fee

Entering charges a gold fee up front, gated behind a confirmation prompt:

entryFee = max(1, floor( (500 + difficultyRank × 100) × dungeonPassMultiplier ))

The Dungeon Pass exploration skill (dungeonEntryCost) is the only discount. It scales linearly to a −75% cap at skill level 100:

dungeonPassMultiplier = 1 − 0.75 × min(level, 100) / 100

Note the Dungeon Pass discount applies only to normal dungeon entries — it does not touch echoed dungeon fees.

Fee table

Dungeon rank	Base fee	With Dungeon Pass at cap (−75%)
10	1,500 g	375 g
25	3,000 g	750 g
50	5,500 g	1,375 g
75	8,000 g	2,000 g
100	10,500 g	2,625 g

Richer drops inside

Two dungeon bonuses stack on every kill’s loot roll:

Bonus	Value	Constant
Drop-chance multiplier	×1.5	`DUNGEON_ITEM_DROP_CHANCE_MULTIPLIER`
Magic-find bonus (added to your MF)	+1.5	`DUNGEON_MAGIC_FIND_BONUS`

The drop-chance factor multiplies each item’s roll chance (clamped to 100%), and the +1.5 magic find is added to your own magic find when rolling rarity — so dungeon loot both drops more often and rolls rarer. Combined with the boss’s ×4 special drop-chance, the encounter-9 kill is the single richest roll in the run.

Scroll of Amnesia on repeats

On repeat boss clears only (never the first clear), the boss has a 2% chance to drop a Scroll of Amnesia (SCROLL_OF_AMNESIA_BOSS_DROP_CHANCE = 0.02). Expected haul is one scroll per 50 repeat clears on average.

Worked example — a repeat clear at rank 50

You re-enter a rank-50 dungeon (no Dungeon Pass):

Pay 5,500 g entry fee.
Gold from the nine kills: 0 (dungeons pay no per-enemy gold).
Gold from clearing: 0 (first-clear reward is one-time only).
Net gold: −5,500 g — repeat runs are a loot activity, not an income one.
Scroll of Amnesia: 0.02 expected (2% from the boss) → ~1 scroll every 50 runs.
Loot: nine kills at ×1.5 drop chance and +1.5 MF, with the boss at ×4 special drop-chance.

The takeaway for min-maxers: farm repeat dungeons for gear and scrolls, never for gold. Level the Dungeon Pass to soften the recurring fee.

Normal vs. echoed

The echoed dungeon is a completely separate mode flagged by dungeonRun.isEchoed, covered on the Echo Ascension page. Key differences:

	Normal dungeon	Echoed dungeon
Entry fee	`500 + rank × 100`, Dungeon-Pass-discountable	Flat 250,000 g (regional) / 500,000 g (Dark Citadel finale)
Dungeon Pass discount	Yes	No
Attempts	Unlimited (re-enter freely)	One attempt — items consumed regardless of outcome
Extra cost	—	Consumes the region Key (or 4 Organs)
Enemy level	Dungeon tile’s own rank	Fixed 125 (regional) / 150 (finale)
Drops	Capped at hero max level	Capped at hero max level, plus a guaranteed Organ / Pendant
