Item description:

first press select (map) then set your map icons with (X) and turn all icons off except for the feathers and flags.
Both are pretty close to each other in the center of the map. the feather is pretty easy to get to on top of the collosium,
the flags a bit trickier. near the flag theres an aquaduct the runs adjacent to the column and over the small valley to the
west. Just follow the aquaduct to its end and climb up there. run back (on top to the duct) to the flag, jump over and grab
the flag for the cheevo.
