1. Choose a probability

Custom values are user inputs. Public presets are cross-source snapshots, not permanent in-game guarantees.

2. Set your plan

Leave cost blank when the current source or live menu does not confirm it. Budget results will show Data unavailable instead of guessing.

How to use it

Choose a public probability snapshot or enter your own observed chance. Then select the task that matches your decision: estimate a fixed number of rolls, work backward from a target chance or check what a resource budget can support.

What results mean

Chance is the mathematical probability of at least one target in independent rolls. Expected attempts are an average, not a guarantee. Expected Stat Locks multiply the average attempts by the number of locks you enter.

Assumptions

This tool does not know hidden pity, banners, guarantees or live costs. It uses the probability and cost you provide, labels public presets as cross-source and shows Data unavailable when a cost is missing.

Calculation scope and data status

This planner applies independent-roll math to a probability you provide. It does not encode hidden pity, banner rules or an official guarantee. Public stat tables report Z at 0.15% and Unbound traits at 0.1%; enter the value that matches the system you are planning.

Mode: user-input · Presets checked with their listed sources. Verify the current stat or trait screen after an update.

Frequently Asked Questions

Is this an official Anime Expeditions calculator?

No. It is a transparent planning aid using your probability input and an independent-roll assumption.

What does locking a stat change?

The planner treats each locked stat as one Stat Lock spent on each reroll. It does not change the target probability unless you provide a different probability.

What probability examples are publicly reported?

The public stat guide reports Z at 0.15%, while the traits guide reports Unbound at 0.1%. Verify the live UI after updates.
