First-hand test plan
Luck evidence capture table
Displayed values and observed samples must stay separate. A finite roll sample cannot reverse-engineer a hidden formula with certainty.
| Baseline Luck | Upgrade level | Displayed after | Potion | Event | Rolls | Observed distribution | Server type | Patch date |
|---|---|---|---|---|---|---|---|---|
| No dated current-place Luck sample is published yet. Unknown formula fields remain blank. | ||||||||
Avoid bad assumptions
Limits and common mistakes
Do not enter a guessed multiplier
A guessed Luck value can make a precise-looking result wrong.
Legacy boosts need reconfirmation
Old potion or upgrade names are candidates only until they appear in the current game.
Rare does not mean guaranteed
More attempts or better Luck can improve probability without ensuring a hit.
