Prasinos Outpost (Location)
A nasty little Roman outpost in the Green Mountains.
You have the chance to storm the place during the Carpe Diem side quest, which offersyour best opportunity to clear the camp entirely. Scan for an overview of where things are inside, with the treasures in tents on the west and east sides of the camp.
Start by scaling the outer wall, up to the twin guard towers over the gate.
Once you're inside, it's only a matter of time before the rebels attack, so start by sniping the quest target Severus, to make sure he doesn't get lost in the confusion.
Do the same to the captain and commander, for the same reason. Snipe anyone else who looks like they need it (there are ammo refills up here), then take to the turret for some more indiscriminate killing).
It will run out of ammo eventually, so mop up any survivors the old fashioned way. When the camp is clear, visit the two treasure locations, that one tent on the eastern side, where the treasure is in a small carbon crystal box on the table,
and one in that tent on the western side, where the treasure is in a large red chest.
Snagging that completes the location.
There are prisoners that can be freed as well, but there are hostiles mixed in with them.
