The player's Luck increases the odds for rare events to occur during a run.

General Description[]

Luck improves the chances for the player to experience more lucky events. This is done by having every luck-based event in the game include a luck modifier attached to it. The prime examples of these are the drops of Fertilizer, Pickaxes, higher tier seeds, and rare seeds, including Heart Beet, Rose, Pumpkin, and Sunflower seeds. Dicey's Casino is also affected by this as well. In essence, the higher the player's Luck is the more likely they are experience more of these positive events. For the majority of these examples, this simply means more drops of those pickups, with the rate of this varying between each given object. For Fertilizer specifically, one Luck equates to about +1% Fertilizer drop chance. For Dicey's Casino, this means increased chances to get the jackpot or otherwise better drops.


Luck affects specific probabilities of some aspects of the game. How Luck impacts an event is defined by the following equation:

Where Luck is a percent, New Probability is the probability of the event after Luck has been applied, Base Probability is the decimal or whole number corresponding to an event, and Scaling Factor is the coefficient controlling how much Luck affects the event. Some instances include, but are not limited to, what is detailed in the table below.
