I looked through the additional resources for Orcs of Golarion and did not find anything saying I could not take the War Rhinoceros as my animal companion.
In the book the last line states, "An orc can take a war rhinoeceros as an animal companion."
I was curious if it was legal in PFS.

I have read the description for this trait, its from Qadira, Gateway to the East p. 9.

You have been trained in the javelin and the spear, and know how to make the best use of your momentum. Whenever you move at least 10 feet before making an attack with a thrown weapon, you add 10 feet to the range increment of the weapon thrown. You can only gain this benefit once per round.

Is the trait valid for all thrown weapons are just the two items mentioned in the description? And the net also reads its maximum range is 10 feet. Would it increase the range increment to 20 feet for the traits purposes?
