Friday the 13th

Today is Friday the 13th! Watch out! Bad things can happen on Friday the 13th.

On January 13, 2006, adventurers noticed that extra text appended to win messages of fights after a Friday the 13th message appeared at the bottom of the main map. The messages have continued each Friday the 13th since.

It is unknown at present if these text messages have any purpose other than amusement. They don't appear to affect the outcome of those fights and the appearance of the text appeared to be random.

Notes

• If you have a Snowy Owl familiar equipped the message reads:

<name> hoots ominously three times. Damn it.

• You can also get the hooting owl message without a Snowy Owl familiar equipped.
• If you break the giant mirror in the Sorceress's lair, you get a message saying:

You get the feeling that maybe you shouldn't've done that. Damn it.

• If you include the Snowy Owl familiar message, there are 13 messages. Spooky!
• These messages also show up if you have the effect Bad Luck.

References
