One private lab for scarce resources
Know what you can afford—and what you can skip.
Stress-test a deadline, work through recorded Heart sources, then plan dye jars and color slots without an account or copied cosmetic imagery.
Deadline stress test
Build a realistic currency runway
Include the days or weeks you expect to miss. The required rate and projection update immediately.Structured tree and dyeability records come from a community-maintained dataset; mechanics summaries link to official support. Live changes can arrive before either source is refreshed.
Questions players ask
Short answers, without making you convert another time zone.
Does the runway know my live balance?
No. You enter a scenario yourself. Every value stays in this browser and can be changed without connecting a Sky account.
Why are there several Heart nodes for one spirit?
Permanent, seasonal, Traveling Spirit and special-visit trees can have different dates, paths and prices, so the planner keeps each recorded source separate.
Are the dye previews exact?
No. They are original flat swatches for planning color demand. Sky materials, lighting and item-specific dye masks will produce different in-game results.
