The day ladder
Official survival badges are Day 1 (Just Getting Started), then days 5, 10, 20, 30, 40, 50, 60, 70, 80, and 90. Rescued! is day 100. Stranded is day 250. Gone Missing is day 500.
Party size at day 100 is its own set: All Alone for solo, Blunder Buddies for a duo, Three's a party for a trio, Four is plenty for four players, and And they were crewmates... for a full group of 5. Server size on the experience is 27, so a full group of 5 is a badge rule, not the server cap.
After the first day 100
Challenge badges 1 through 6 ask you to complete that tier of challenge mode. A 10 November 2026 account of developer posts says Challenge Mode opens after you survive 100 days once, with six harder tiers. The same account says Pro Servers, added 2 November 2026, are limited to players who have reached 100 days.
Other counters that are not bosses
- Mr Money Bags: spend 1,000 Doubloons in one run.
- Plunderer: open 100 chests in one run.
- Money Marauder: open 500 chests. The badge text does not say this one must be a single run.
- We Need To Cook: discover every potion recipe in the potion index. Individual recipes are not published on the badge.
- Get Off My Planet: 1,000 alien kills.
Multipliers
Corruption badges mark 10x, 15x, and 20x multipliers from the corruption. They do not explain the button that raises the multiplier. Time Corrupted is the 10x step and is the one most players will see first. Do not treat a fan page's day-skip machine as required unless you can craft it in the current menu.
Leaving a server
Comments on a March 2026 walkthrough say a run restarts when you leave. Many badges explicitly say single session or single run, which fits a run that does not pause. Class unlocks are described as permanent, and Pearls are the lobby currency. This wiki does not claim the raft layout itself saves. Check the lobby on your own account after a rejoin before you plan around a saved base.
