So far I caught a Timeworn Boarskin Map while fishing and waiting for the Crystal Tower FATE to spawn.
So far my only complaint is that when the treasure map is deciphered it shows you where to dig on a small map AND tells you which zone to go to. I think being told exactly what zone to dig in defeats purpose of hunting the treasure. Could we get this feature removed so that we are only given a small picture of the general location?
I'll post what I get as a reward when I get around to finishing it.
Edit: Even for a solo fight ALL members of your party must be in the area.
Three waves of monsters spawned.
Reward:
Free-fall loot: Dodo Tenderloin HQ, Dodo Egg, 5 swan feathers, 180 lightning shards, 2 handfuls of mythiril rings hq, 2 undyed felt HQ, 211gil,
Tomestone reward: ONE mythology tomestone
Loot pool: Aqueous Whetstone.
