These are not easy to get (unless you're just plain lucky). Here are some helpful facts about this camp:
1) The Battlemaster cannot spawn in either location, only in the spot on the right as you are facing them (in other words, you're looking right into their faces... as you would if you were coming from the Akheva zone).
2) If he has the hammer in his hand, he will not have the shoulders (may have a Goranga Idol though).
3) The lower level Battlemasters (light blue to a 65) will drop hammer and/or shard and/or nothing. The higher level Battlemasters (blue to a 65) will drop the pauldrons and/or shard and/or nothing.
4) Another way of saying it: Higher level Battlemasters are the only ones which drop the pauldrons. Lower level Battlemasters are the only ones which drop hammer. Any can drop shard. None will drop both hammer and pauldrons.
5) Battlemaster/PH spawns are 24min 40secs apart.
If you are campng this item, don't get too excited if the Battlemaster pops and has the hammer in his hand... he won't have pauldrons (he will also con light blue to a 65). Also, the lower level Battlemaster seems to be the more common spawn. Just guesses here in this chart, but probably pretty close to the odds:
Battlemaster spawns about 5% of the time in that one spot (making him quite rare, 1 in 20 chance).
Lower level Battlemaster spawns about 75% of all Battlemaster spawns, so higher level one would cover the other 25%.
Of the higher level Battlemaster spawns, about 80% will drop the pauldrons.
Any Battlemaster has about a 50% chance of dropping shard.
Do get excited if a Battlemaster spawns and has no hammer and is dark blue to a 65, there is a very high chance he will have pauldrons... but it's not certain.
