To pick a mechanical lock, you need a [[Crafting items#Toolkits|Lockpicking kit]] and a mechanical lock to defeat. The actual lockpicking process is conceptualized through a minigame, which is a variant of the [https://en.wikipedia.org/wiki/Mastermind_(board_game) Mastermind board game], with the GM as codemaker, and the players as codebreakers.
A code is composed of four symbols, each of which can be one of six different types. They can be conceptualized as numbers (123456), letters symbolizing their colors (RGBYOP), or by directly using emoji (🔴🔵🟢🟡🟠🟣🔴🟢🔵🟡🟠🟣).
When a player intends to start picking a mechanical lock, the GM must randomly determine the lock's correct combination '''in secret''' by rolling 4d6, and referring to the table below:
