Warning.

Exploration Stage: Cards of Fate
From: Cardsharp
Description: I always thought slot machines were for entertainment, but this one seems to have some other purpose... this machine has what looks like an old sign on it. What does it mean?
Completed: I've never seen a sign with a smiling mask on it. Have you seen it? It looks as if it's warning us about something! Perhaps this machine was used in a comedy?
