Data guide / additive stacking
Fish It Luck guide
A practical reference built from the prepared Luck system dataset: what stacks, where the numbers are known, and which boosts still need an in-game value.
Luck is treated as one additive total
Luck is the single most important stat in Fish It. A higher total Luck value increases the probability of hooking rarer fish (and Secret fish specifically). Luck is expressed as a percentage bonus that is summed from all active sources (rod + bait/bobber + enchantment + potion + totem + friend + server + event + new-player boost) into one total Luck stat, which then scales rare-spawn odds.
Each cast is an independent RNG roll against a base per-fish chance (e.g. 1 in 4,000,000 for the rarest Secret fish). Raising Luck effectively increases the roll's odds of landing on rarer tiers. Community guides describe the relationship as roughly proportional: higher Luck % = proportionally better chance at rare/Secret spawns. No exact published closed-form formula from the developer; the community models each cast as independent with no pity/carry-over.
