How likely is your next dig to be something rare? Drop rates by tier, and how Luck boosts change them.
| Rarity | Base Drop Rate | Notes |
|---|---|---|
| Common | ~18.5% (≈1 in 5.4) | Community-estimated |
| Unremarkable | ~5.7% (≈1 in 17.6) | Duplicate-protection filler outcome |
| Rare | ~5.9% (≈1 in 17) | Community-estimated |
| Ultra Rare | ~2.0% (≈1 in 51) | Community-estimated |
Dig & Clean confirms a Luck stat: the higher your detector and gear Luck, the better your odds of digging up rare antiques and treasure. The clearest proof of this is the game's own reward design — both codes added with Update 1.0 are pure Luck multipliers (UPDATE1 grants 2x Luck for 30 minutes, SECRET10 grants 10x Luck for 10 minutes), which only makes sense if Luck is a real mechanic driving rarity odds. Redeem them on the codes page before a farming session.
What isn't confirmed: the exact formula for how multiple Luck sources stack (additive vs. multiplicative), and a community claim that Luck "feels higher" when playing in a group — one fan wiki explicitly labels that a theory, not a confirmed mechanic. We won't publish either as fact until it's verified in-game.
