Map Layout
Additional info
7 columns, 7 paths drawn from the bottom row
17 floors: the Ancient, 15 rooms, the boss · 16 in co-op, one room fewer
The first room is a fight; the first 3 fights come from the weak pool
5 elite rooms (8 with Swarming Elites), never in the first five rooms
A rest site always sits on the row before the boss, never in the first five rooms
Treasure and merchants never follow their own kind; a fork never repeats a room type
A ? room is usually an event: a fight 1 in 10, a merchant 3 in 100, a chest 2 in 100Bosses
In a standard run you get a boss you have not fought yet, until you have met all 3. A boss pays 100 gold (75 with Poverty).
Elites
Never the same elite twice in a row. An elite pays 35 to 45 gold and drops a relic.
Weak pool
Each is 1 in 4. No fight comes twice. A fight pays 10 to 20 gold (7 to 15 with Poverty).
Full rules
The first 3 monster rooms you enter take their fight from these 4. The game deals the fights out before you climb: it takes them from the pool one at a time, each equally likely, and puts none back until the pool is empty.
Some fights never follow each other, in either pool: Fuzzy Wurm Crawler and Overgrowth Crawlers; Shrinker Beetle and Overgrowth Crawlers; Group of Slimes, Shroom and Slime and Swarm of Slimes. The game skips such a fight while it has another one to deal.

61 HPEach is 1 in 12. No fight comes again until all 12 have come up. A fight pays 10 to 20 gold (7 to 15 with Poverty).
Full rules
Every monster room after the first 3 takes its fight from these 12. The game deals the fights out before you climb: it takes them from the pool one at a time, each equally likely, and puts none back until the pool is empty.
Some fights never follow each other, in either pool: Fuzzy Wurm Crawler and Overgrowth Crawlers; Shrinker Beetle and Overgrowth Crawlers; Group of Slimes, Shroom and Slime and Swarm of Slimes; Shroom and Slime and Overgrowth Flora. The game skips such a fight while it has another one to deal.
Events
What the map holds
Rooms on the map
Seven columns from seven generated paths hold:
Shops: 3
Extra rest sites: 6 or 7
? rooms: 10 to 14
Elites: 5 (8 with Swarming Elites, Ascension 1)
Fixed rows
First row: all fights.
Ninth row (seven below the boss): all treasure.
Row under the boss: all rest sites.
Elites and extra rest sites never land in the first five rows, and rest sites also skip the two rows beneath the fixed rest row.
Which fights you meet
Weak pool: covers the first three Monster rooms you enter, and a ? that rolls a fight counts, so early ? rooms spend events while the easy fights wait.
Normal fights: the twelve normal encounters are pre-drawn once each, so no normal fight repeats.
Elites: pre-drawn with no back-to-back repeats, so your first three elite fights are all different.
Byrdonis and Phrog Parasite are short, Bygone Effigy at 127 HP is long.
Notes
How the map is dealt
- Queue: point types come from a queue (rests, shops, elites, then ? rooms) dealt over shuffled points.
- In a line: elites, rests, treasure and shops never directly follow their own kind.
- At a fork: rests, fights, ? rooms, elites and shops never share a parent with their own kind.
- Clean up: leftovers become fights, duplicate path segments are pruned, and a repair pass refills any type that fell short.
Tagged fights (slimes, mushroom, crawler, shrinker) never repeat back to back.
What a ? room rolls
Fight: 10%
Treasure: 2%
Shop: 3%
Event: otherwise, never an elite
Misses grow by their base chance, hits reset, and the odds reset each act.
Boss
- The boss roll is even, but a Standard run gives you the first unseen boss: Vantom, then Ceremonial Beast, then The Kin.
Double Boss (Ascension 10) touches only the final act.
A profile's first run
Fights, in order: lone Nibbit, slimes, Shrinker Beetle, Inklets, Mawler, Ruby Raiders, pair of Nibbits.
Events: Byrdonis Nest then Sapphire Seed; the first two ? rooms are events.
Elites: Byrdonis then Phrog Parasite.
