Hero Star Calculator Calculate universal fragments between standard star stages.
Set your target
How standard stars work
Each full star contains five sub-stages. The fragment cost increases as the hero moves through higher star levels.
| Star earned | Per sub-stage | Five stages | Cumulative |
|---|---|---|---|
| 1★ | 5 | 25 | 25 |
| 2★ | 10 | 50 | 75 |
| 3★ | 20 | 100 | 175 |
| 4★ | 60 | 300 | 475 |
| 5★ | 100 | 500 | 975 |
Standard 0★–5★ fragment curve used here: 5, 10, 20, 60, and 100 fragments per sub-stage, for 975 fragments from 0★ to 5★.
Hero Experience Calculator Calculate Hero EXP required between two levels.
Set your level goal
How the calculation works
The calculator adds the EXP required for every level after your current level through your selected target. For example, level 100 to 105 includes the costs for levels 101, 102, 103, 104, and 105.
Selected level path
| Level reached | EXP required | Cumulative |
|---|

Migration Estimator Estimate migration score, identity tier, passes, and saving time.
Step 1
Enter your account power
Use the values from your profile's power details. Enter full numbers or use the quick-add buttons. Troop Power is intentionally excluded.
Community estimate used
Estimated score = (Structure + Tech + Hero + 3 × Modified Vehicle) ÷ 6. This community formula is useful for planning, but it is not an official Last Z formula.
What to enter
Permanent account power
Use Structure, Tech, Hero, and Modified Vehicle Power from the account-details panel. Troop Power is not included in the community estimate.
Important
Do not plan to the exact border
Tier thresholds may differ by server group or migration cycle. When your estimate is near a boundary, save enough passes for the next tier whenever possible.
Saving plan
Start buying passes early
The Glory Shop commonly limits free acquisition to one Migration Pass per week. A 20-Pass target may therefore require roughly 20 weeks without previously saved passes.
Planning Reference
Estimated identity tiers
The calculator updates these ranges when you select a different tier profile.
| Identity | Community score range | Estimated Passes | Migration access |
|---|
Unofficial community estimator. The exact Last Z migration formula, historical-power handling, tier thresholds, destination quotas, and approval rules may change. Confirm all requirements in the live State Migration event before making account or purchase decisions.
