Luck

Fortune Teller

Luck Luck.png is a statistic that affects many different aspects of the game, such as the chance of finding geodes and chance of getting treasure from Fishing. There are several sources of luck: daily luck determined by the game, buffs gained from eating certain food and drink, a Special Charm which gives a small permanent luck boost, and the Lucky Ring.

Daily Luck

The base value for daily luck is a randomly generated number from -0.1 (unlucky) to 0.1 (lucky).[1] The value is increased by 0.025 with the Special Charm. The value is used in numerous ways; though it looks like a percentage equal to 10%, it is in fact treated differently in every situation and may have a minuscule or enormous effect depending on the activity.

Daily luck can be checked by right-clicking on the Television and selecting "Fortune Teller." The Fortune Teller will give an indication of the daily luck stat modifier. Luck is determined at the start of the day and is not affected by choosing to view the Fortune Teller Television Program. Daily luck does not change if the day is restarted, but it can change by replaying the previous day.

Before revealing the luck message, one of the following messages is shown randomly (the first two being gender-specific). They do not affect the luck in any way.

“Ah... I sense that a new viewer has joined us. A young man from... Stardew Valley? Welcome, welcome!”
“Ah... I sense that a new viewer has joined us. A young lady from... Stardew Valley? Welcome, welcome!”
“Ah... yes, I can hear the spirits whispering something to me... ”
“Welcome back to 'Welwick's Oracle'... If you seek hidden knowledge of the future, well you've come to the right place.”
“Hoo.. I see a glimmer within my scrying orb... A shard of knowledge from the future!”
“Welcome to Welwick's Oracle... the ONLY show where the voice of the spirits is channeled directly... to YOU.”

LuckSkullMin.gif Luck.png Luck (-0.1 or -0.075 with Special Charm)

Daily luck has 201 possible values[1], so the probability of getting best possible luck, worst possible luck, and absolutely neutral luck are 1/201 each. Due to a rounding error in the game code, it's impossible to get absolutely neutral luck with the Special Charm[3].

Special Charm

After reading Secret Note #20 and solving the puzzle depicted, the player is awarded with a Special Charm that permanently increases daily Luck by 0.025.

Daily Luck Effects

Daily luck affects the following:

Mining
Fishing
Other

Luck Buffs

Luck Buffs are temporary bonuses gained from:

Only one drink-derived buff and one food-derived buff can be active at a given time. However, dishes from the Chef at the Desert Festival can stack on top of the food and drink buffs, which includes any luck buffs potentially received from the dishes. A buff of +2 for example may have similar effects to a daily luck value of 0.1, though it is treated differently in every situation and may have a minuscule or enormous effect depending on the activity.

The following food and drink provide a temporary luck buff:

Luck Buff Effects

Luck buff effects are very similar to daily luck effects. However, total luck buff is treated separately from total daily luck, and the effects of the two types of luck are not the same. The types of events affected by luck buffs are different, and for events affected by both, the magnitude of the effect can be very different.

Luck buffs affect the following:
