Can I save multiple plans?

Yes. Use Add to backlog to keep a list of planned ascensions and manage them in the Backlog section.

Does this use exact material tables?

Currently it estimates based on level difference. We’ll add per-resonator and weapon tables with ascension breakpoints soon.

Where is my data stored?
