We dug up about 16 treasure maps and did them all in one night. It was impressive. Many of the encounters gave 5000 gil each and all kinds of strange tradeskilling items. The second night we did about a dozen more, and were not so lucky with the gil. This might be because some people forgot their lucky minions on the second night.
We would spawn the treasure map, kill the map boss, and any other mobs or fates that happened to be around.
Then we would move on to the next map spot. A different Phanker leading the way for their map. (Players can hold up to 2 maps at a time.)
The above treasure map was a bit of a mistake, but hilarious.
Very good times.
