I have a vague memory of text discussing weapons, maybe with the trip quality, to perform these manuevers. Now I can't seem to locate it, anyone know where to find this, or am I imagining it?
Paizo Blog: Combat Maneuvers and Weapon Special Features has everything I've ever found on the subject--specifically
There is a special exception to the above rules. If you’re using a weapon with the trip special feature, and you’re attempting a drag or reposition combat maneuver (Advanced Player’s Guide 321–322), you may apply the weapon’s bonuses to the roll because trip weapons are also suitable for dragging and repositioning (this also means we don’t have to add “drag” and “reposition” weapon properties to existing weapons).
Thanks, didn't think to go check blogs for this. And as a bonus, no new evidence for me going nuts.
