Floor 3: Race and Class Selection

Overview

Floor 3 is the Over City -- an urban environment inside a dormant volcano with a day-night cycle (nights are dangerous). This is where crawlers choose their race and class, the foundational decision that shapes everything going forward.

The System AI recommends three race options but crawlers may have hundreds to choose from. Each race comes with stat bonuses, penalties, and sometimes dramatic physical transformations. Class selection happens here too -- over 127 documented options ranging from Fighter and Mage to Vape Shop Counter Jockey and Banana Farmer. The AI assigns classes based on crawler behavior. The AI is creative about this.

Approximately 700,000 crawlers remain at the start of Floor 3. By the end, that number drops sharply.

Carl's choices

• Race: Primal -- the human-adjacent base race. Enhanced physical stats without exotic abilities. Carl stays close to human. The AI considers this "on brand."
• Class: Compensated Anarchist -- trapmaking, bomb-making, social-media manipulation. The AI's description of this class is essentially a summary of Carl's personality converted into game mechanics. Later specializes into Agent Provocateur on Floor 6.

Key characters

• Katia Grim joins the party. Doppelganger race -- can reshape her body mass. Former art professor from Reykjavik. Quietly becomes one of the most competent crawlers in the dungeon.
• Mongo hatches from an egg (adopted on Floor 2, hatches here). Velociraptor. Immediately starts eating everything.
• Bautista joins. Former Philippine Army soldier. Berserker class. Katia's partner. Perpetually cheerful despite circumstances.

Key mechanics

• Race selection -- stat adjustments, physical transformation, new abilities. ~80% of crawlers keep their original race.
• Class selection -- skills, spells, stat boosts/penalties, determines your build for the rest of the crawl
• The sponsorship system begins -- crawlers gain sponsor slots, adding a corporate layer to survival
• The leaderboard goes live -- top 10 crawlers become public targets with bounties on them
• Day-night cycle -- Floor 3 has actual time-of-day mechanics. Nights spawn tougher mobs.
