The true identity of the four-armed bandit is revealed
after you've collected enough treasures to gain
a Treasure Hunting Rank of "S." You can
view your rank at any time by speaking to the Four-armed
Man or the woman at the Treno Inn.
you reach Rank S, go speak to the Four-armed Man
in Daguerreo. This is the same person who has
all the rare airship cards, if you challenge him
to a card game. When he finds out that you're
a Rank S treasure hunter, he becomes intimidated
and abruptly runs out. Follow him to the entrance,
and he will tell you his true identity and hand
you the Rank S Award Key Item.
Hunter Ranking is determined by a point system:
point for every chest, searched Field icon, and
item gained in event sequence, and every rare
item purchased in the Treno Auction House (with
the exception of Magical Fingertip and Pearl Rouge).
2 points for every chest found on the World Map
while riding Choco.
No points are awarded for items found while digging
in the "Chocobo Hot and Cold" game or
bought from Stiltzkin.
