Encounters

Things that find you in the Depths: a goblin with a sack of borrowed loot, and the monster that remembers the last time it killed you.

Pipsnizzle the Thief

Hearthold's payroll goblin, off the clock, in a black domino mask. Catch him before his portal opens.

Appears on about 1 eligible floor in 12 (less in Bramble Hollow); after 18 floors without him, his odds climb by 2% a floor, up to 30%.
Not until you've cleared 3 floors. He spawns at least 12 tiles from where you arrive and is spotted within 8 tiles.
Once spotted he runs, jukes every 1.2–2.2 s and opens his portal after 12 s (a 1 s channel: still killable).
Stuns, freezes, fear, roots and silences turn into slows; slows land ×1.3 harder (at most 80%) and shake 3 coins loose. He drops a coin trail as he runs.
His health is about 5 seconds of an on-level hero's damage (more for a party).
Catch him: 12 gold piles, 2–4 materials, a rare item for your class (30% epic, 5% legendary), 2 more items, maybe a potion, a scroll or a ledger page.

His Vault

5% of kills leave his portal open (more after 10 kills without, up to 15%). Inside: 10 chests, 2 rare chests and 20 coin piles. The exit takes you down a floor; unclaimed loot stays behind.

The Mayor's ledger

10 pages drop from Pipsnizzle, one at a time. Bring them all home.

Page	The Mayor wrote
Petty Cash	Petty cash box: 40 gold. Counted twice.
Fountain Fund	Fountain repairs (the chasm ate the south half): 900 gold.
Hero Wages	Heroes: paid in glory, exposure, and one free potion.
The Bench	Commemorative bench for our favourite hero: 300 gold.
Chestnut Levy	Chestnut vendors roasting on the Deep: tax them.
Seal Polish	Polish for the five Seals: 5 jars.
Mimic Insurance	Insurance against mimics in the town hall: denied.
Narrator's Fee	Narrator (Quillon): fee waived, on account of being dead-ish.
Payroll	Payroll clerk (Pipsnizzle): 1 salary.
Bottom Line	Year's balance: somehow short. Every year. Mysteriously.

The Nemesis

The monster that killed you gets a name, an epithet and a crown. It gloats on your death screen, then comes looking for you.

Die to an elite, a champion or a wanderer and it becomes your nemesis; a plain foe only 35% of the time. Up to 3 at once.
Each time it kills you again it ranks up (to 5): Blooded, Twice-Blooded, Thrice-Blooded, Crowned, Tyrant-Touched. Elite affixes grow too, up to 5.
It comes back: 15% a floor in its own dungeon, 8% elsewhere in its act, 10% within 5 depths in the Descent, +3% per floor since you last met (at most 45%), never within 10 tiles of the stairs.
Vengeance: ×3 XP, a guaranteed epic, +10% legendary chance per rank and 9 gold piles. Its trophy goes in your Hall of Vengeance (up to 24).
In co-op a friend's nemesis can walk your floors; help them settle it.

Rank	Level	HP	Damage
1	+1	+15%	+8%
2	+2	+30%	+16%
3	+3	+45%	+24%
4	+4	+60%	+32%
5	+5	+75%	+40%

Epithets it might earn: the Heroslayer, Skullsplitter, Bane of you, the Unkind, Twice-Lucky, the Grudgebearer, Hero-Eater, the Undefeated…
