Item description:

Perhaps the biggest grind in the game. USA and EU are same GAME ID
This trophy also has a current easy glitch that can prevent you from getting unless you replay the entire game/grind.

The last location is a Hyena Lair. (Picture included in zip of location on map)
Fast travel close then use your bird to locate the boss of the lair, and kill it however you want.

This is the last trophy I needed so some others may pop like the one for having all legendary gear equipped or master ability.
I recommend getting the other stuff done then saving yourself the 20 hours grind for this one.
After completing the Hyena Lair this then becomes essentially my "Platinum Save."

Some other trophies others have easily obtained from this save:

I'm a Legend
Be equipped with only Legendary equipment.
(Just go buy a Legendary Mount)

Overdesign
Kill a poisoned level 35+ enemy with the torch in less than 30 seconds.

Free as a Bird
Use the eagle for a total of 30 minutes.
(Fly for a second)

BOOM!
Kill 30 enemies by shooting a fire arrow at oil jars.
(Kill 1 more)

and probably some more...
