The floor-four rule opening bounty hunting on the top-ten crawlers, turning fellow crawlers into threats.
With the leaderboard's public debut on The Iron Tangle, Borant Corporation declares "hunting season": every top-ten crawler now carries a bounty, and killing one yields a loot box worth the reward. Carl and Princess Donut, both listed with 100,000-gold bounties, must now fear their own kind as much as the mobs. The rule reshapes the party's behavior — guarding information, hiring Desperado Club security, and staying wary even of allies like Hekla — and pays out only 10% of one's own bounty for surviving the floor.
A game-rule change announced by the system, manifest in bounty figures beside names on the leaderboard.
The floor's defining social threat, turning crawlers against one another.
