Gravestone
Gravestone

The Gravestone is a Miscellaneous NPC that allows players to Try Luck or Pray at night for various rewards. It also serves as the starting point for the Skull Guitar puzzle during a Full Moon.
Usage:
The Gravestone can only be interacted with at night and has a 15-minute cooldown after each use. Upon interacting with it, players are presented with two options:
Try Luck
Pray
Players can only select one option per night. Attempting to interact with the Gravestone again before the cooldown expires displays the message: "Nothing happened, maybe you should come back later?"
If the dialogue says "You Prayed", it means the player died while attempting the Skull Guitar puzzle and cannot continue it during that attempt.
During Full Moon
Choosing Pray during a Full Moon may prompt the player to play a puzzle. Completing the puzzle unlocks access to the Weird Machine, which sells the Skull Guitar.
If the player has already completed the puzzle, the Pray option behaves as normal and will not start it again.
Location
The Gravestone is located in the graveyard of the Haunted Castle in the Third Sea.
