Flood Day Planner
Interactive DIVE or DIE Flood Day Planner — calculate remaining dive days and plan your Eldritch Idol hunt.
Plan Your Campaign Timeline
The Flood Day Planner helps Chiefs calculate effective remaining dive days based on current countdown, difficulty setting, Eldritch Idols collected, Worship days gained, and underwater altar sacrifices used. Input your run state below for personalized recommendations.
Normal difficulty starts at 40 days; Hard starts at 30. Each dive consumes one day. Worship and altar sacrifices add days back. The tool accounts for these variables to suggest early, mid, or late-game focus areas.
How to Use This Tool
Enter your current countdown value visible on the settlement HUD. Select your difficulty. Input Idols found (0–8), Worship days gained, and altar sacrifices completed. Click Calculate to see estimated effective dive days and strategic advice.
Use alongside our Eldritch Idols Guide and Final Flood Day Guide for complete campaign planning.
