PokéBonk guide
Luck in PokéBonk
There’s no single number where Luck is “full”. Several systems read it, and each stops improving at a different point.
What Luck affects
| System | Rule | Useful past the cap? |
|---|---|---|
| Natural shiny in this zone | Extra chance = Luck ÷ 1000, at most +8 points (cap at Luck 80) | Yes, quality and others still benefit |
| Slot machine winning tier | Winning-tier chance at most doubles, capping at about Luck 100 | Yes, the quality of won items still changes |
| Special supplies from rocks | 15% × Luck multiplier, at most 100% | This cap is different from the slot machine’s |
| Item and upgrade quality | Higher Luck shifts existing weights towards higher quality | No shared cap of 100 |
So “Luck stops working at 100” isn’t true.
Natural shinies: only read at the roll
P = [0.08 + min(0.08, Luck ÷ 1000)] × Charm multiplier
| Luck at the roll | No Shiny Charm | With Shiny Charm (×1.5) |
|---|---|---|
| 0 | 8% | 12% |
| 40 | 12% | 18% |
| 80 or more | 16% | 24% |
The roll happens once each time you enter a new zone. Luck gained after that counts from the next zone. See shiny odds explained, and the classic shiny guide for its separate cap of 75.
Rocks: more Luck, more bombs
Rocks’ special supplies drop at 15% × the Luck multiplier (at most 100%), split evenly between healing, magnet and bomb.
| Luck | Chance per rock of a bomb |
|---|---|
| 100 | About 10% |
| 500 | About 30% |
| Cap | 1/3 |
Luck sources
| Source | Luck | Notes |
|---|---|---|
| Lucky Punch | +10 | Also +3% crit chance |
| Star Piece (item) | +20 | – |
| Comet Shard | +30 | Also +40% PokéDollars |
| White Flute | +5 | Also +12% enemies, +10% XP |
| Star Piece (vitamin) | +10 × quality multiplier per pick | Not the same as the item |
| Lab: Fortune | +5 per level, 6 levels | +30 in total |
| Shiny collection of 2 | +3 | Permanent |
| Clefairy’s passive | +20 | Passive |
When to forget Luck vitamins
| Don’t forget it yet | Consider replacing it |
|---|---|
| You’ll still shop, open Poké Balls, spin slots or Refresh upgrades | No more shopping or rerolling |
| New zones are still coming with natural-shiny rolls | This zone’s shiny has already rolled |
| – | More KOs are your only remaining goal |
When you replace it, compare the immediate gain from attack speed, physical damage and special damage. The Lab guide covers how to get more Refreshes, Skips and Banishes.
