==Special Charm==
After reading [[Secret Notes#Secret Note #20|Secret Note #20]] and solving the puzzle depicted, the player is awarded with a [[Special Charm]] that permanently increases daily Luck by 0.025.
==Mechanics==
Most random events in the game are determined by generating a random double-precision number in the range 0 to 1 that is then compared to the event's chance of happening. For example, when [[Panning|panning]] for ore the base chance for finding [[Iridium Ore|iridium]] is 1%. This means iridium is only found if the random number is less than 0.01.
Daily Luck typically increases the critical threshold for an event without any change in magnitude: a 0.01 value of daily luck changes the iridium ore panning threshold from 0.01 to 0.02. On the other hand, buffed luck values are significantly rescaled before being applied, with large variability in scale factors. For ore-panning alone, scale factors include 0.001, 0.002, and 0.04 (when deciding the type of ore, whether there's an extra item, and deciding the type of extra item, respectively). For iridium ore specifically the scale factor is 0.001, so if a player has a 0.1 value of Daily Luck and a +1 Luck Buff, the threshold is 0.021 (2.1% chance).
However, the exact meaning of Daily Luck and Luck Buff is always context-dependent, because every event applies luck slightly differently.
