To go further with this point, is a Half Giant treated as both a medium and large creature for use of weapons?
We don't know.
He's obviously a Medium creature, so he can wield weapons as a Medium creature.
Powerful Build, though, is unclear.
The sample NPC wields a Large greatsword with no penalty. If we assume this is intentional, then we know that Powerful Build doesn't do what it says it does (or at least, not
just what it says it does).
Possibilities:
1. Can wield Large weapons without penalty. (As written, but disproven by the sample NPC.)
2. Can wield Large weapons as though a Large creature.
3. Can wield weapons as though a Large creature.
In case 2, the Half Giant cannot wield a Huge longsword in two hands. Nor can he wield a Medium greatsword in one hand. Like Monkey Grip, the ability only affects weapons of one size category.
In case 3, he can do both of the above, because he is considered a Large creature. However, he would take a -2 penalty in both cases, since a Large creature wielding a Medium greatsword in one hand or wielding a Huge longsword in two hands is inappropriately-sized. He could wield the Medium greatsword in two hands at no penalty by considering himself a Medium creature, or a Large greatsword in two hands at no penalty by considering himself a Large creature.
The sample NPC's greatsword does not give us sufficient information to distinguish between cases 2 and 3.
The next question in cases 2 and 3, of course, is whether Monkey Grip applies to the Half-Giant's
effective Large size for wielding weapons, or his actual Medium size.
