It’s in the Barbarian pack.
However, beware. Since the character’s posture doesn’t change, all the big (read HUGE in some cases) weapons available in the barbarian and supernatural muscular package tend to be as big or even bigger than your character, and they can be in the way of the pic being taken correctly. 😉 B)
You know: unrealistic fantasy weapons (or just big, like pole arms) and perspective issues… 🙂
I underdstand why it’s been done, no complaint. But there are very few (read 1, this halberd) which can be placed in the back, all other big weapons are held and the very big ones tend to hide the character, use your imagination. 😉 😛
